4.0 ENVIRONMENTAL IMPACTS / ENVIRONMENTAL CONSEQUENCES

This document has been prepared as a joint EIR/EIS as a result of the combined local, State, and federal actions associated with the approval of the proposed MSHCP. As stated in the Purpose and Need (Section 1.0), the co-lead agencies are the County of Riverside, pursuant to CEQA, and the USFWS, pursuant to NEPA. A consistent format was used to assist the reader in understanding the implications of the proposed MSHCP and alternatives. This section provides a narrative of how the analysis was undertaken and presents the organization of the environmental consequences section of the document.

This section of the EIR/EIS forms the scientific and analytical basis for the evaluation of the proposed MSHCP and alternatives. Topics analyzed include biological resources; land use and planning; population, housing and employment; public services (fire protection and parks); and transportation and circulation. Sections are presented in the following format.

Thresholds of Significance/Criteria for Determining Significance

The criteria for determining significance provide a threshold at which a significant impact will occur. Criteria will differ among issues.

Impact Analysis per Issue Statement

This section of the document provides an evaluation of project-specific and alternatives impacts and determines significance based on documented thresholds levels. The Proposed Project/Action is the MSHCP as described in Section 2.3.1 of this EIR/EIS, to include the whole of the action (policy statements, issuance of incidental take authorizations, and the implementing agreement).

According to NEPA, each of the alternatives to the Proposed Action must be analyzed in equal detail as the Proposed Action. In this Section of the EIR/EIS, each environmental issue described in Section 3.0 of this document is analyzed with regard to potential effects related to the proposed MSHCP (Proposed Action) and to each of the four alternatives as well (Listed, Proposed, and Strong Candidate Species Alternative; Listed and Proposed Species Alternative; Existing Reserves Alternative; and the No Project/No MSHCP Alternative).

The Proposed Action and the alternatives are analyzed for direct, indirect, and cumulative impacts/effects.

Mitigation Measures

For those impacts that were determined to be significant, mitigation is provided in this section of the impact analysis.

Level of Significance after Mitigation

An analysis of the significance of an effect after mitigation is applied is discussed in this section of the impact analysis. The outcome of the analysis is to determine whether there is a significant effect caused by the proposed project or its alternatives that cannot be mitigated to below a level of significance.

for biological resources applies the applicable threshold of significance to the potential effects for the Project and each alternative (with the exception of the No Project Alternative) for each of the following biological issues:

Subheadings for each of these issues appear in the analysis section for the project and alternatives. The No Project Alternative discussion is structured differently, since that alternative does not involve issuance of take authorization. The No Project Alternative discussion is formatted to address existing local, State and federal regulations, and the effects of the application of these regulations to future growth in the MSHCP Area.

Impact Analysis Considerations

Consideration in evaluating impacts to sensitive vegetation communities is based on the vegetation data base developed by Pacific Southwest Biological Services (PSBS, 1995) which is based on 1992-1993 aerial photographs. It is important to distinguish between “vegetation communities” and “habitats.” The terms often are used interchangeably, but a vegetation community precisely refers to definable and consistent assemblages of plant species, whereas habitat is the native environment of a plant or animal species.

The vegetation map as incorporated into the MSHCP database is depicted in Figure

4.1.1. This map was created by PSBS and mapped by KTU+A in 1995. As stated in the February 1995 PSBS/KTU+A Western Riverside County Multi-Species Habitat Conservation Plan Phase I Information Collection and Evaluation Report, this map was created by compiling all known vegetation information within the Plan Area. These data sources include biological survey reports, Weislander vegetation maps, satellite imagery and the Dangermond/RECON data set. Methods used to create and interpret vegetation data included aerial photograph interpretation, edge matching, digitizing, and geographically registering the data. In areas of concern, ground truthing occurred. Vegetation types were classified according to Holland. It should be noted that the vegetation map is representative of conditions at the time of the study; existing conditions today may differ from those represented on the map. The MSHCP vegetation map is limited by the time frame within which the data were assembled as well as the precision of those data. The Project encompasses all of western Riverside County, a

total of 1,966 square miles. Due to the large scale of the Project, it is simply not possible to map the Project area with parcel-level precision. Rather, vegetation mapping was based on a broad scale, as has been done with other criteria-based MSHCPs that cover large geographic regions, such as the San Diego MSCP. The vegetation map represents conditions at the time the data were assembled, in this case 1991-1995; the current extent and character of vegetation communities may differ from that depicted on the MSHCP vegetation map. Published and anecdotal data suggest that ecosystem state transition is occurring within some portions of the Plan Area - in particular, fire suppression has resulted in the conversion of frequently burned chaparral and coastal sage scrub to grassland and in shifts from Ponderosa pine and Jeffrey pine to incense cedar and white fir (Minnich, et al., 1995; Keeley, 1990; Zedler, et al., 1983). The MSHCP incorporates features to update the vegetation map as new information is obtained, such as the development of a new vegetation map as part of the MSHCP Monitoring Program. The timing and methodology for developing this map is described in Section 5.3 of this document. The criteria-based format of the MSHCP was designed, in part, to address changing data and/or conditions. The MSHCP calls for assembly of 153,000 acres of Additional Reserve Lands from within an approximately 300,000-acre Criteria Area. Reserve Assembly will involve review of a variety of project-specific vegetation data to refine and guide the Reserve Assembly process. This criteria-based format differs somewhat from large-scale NCCPs/HCPs for which a specific reserve boundary is delineated on a map at the time of permit issuance. Under that type of approach, validation of the vegetation map at the landscape level may be more important than under the criteria-based approach selected for this MSHCP. The organizational structure established for the MSHCP, as described in Section 6.6 of this document, also provides opportunities to incorporate new information during the term of the MSHCP Permit(s).

Consideration in evaluation of impacts to species is based on the MSHCP Species Occurrence Database. The University of California at Riverside (UCR) has assembled a species occurrence database for use during the MSHCP planning process. This database is accessible via http://ecoregion.ucr.edu/mshcp, and is a clearinghouse for biological information for the MSHCP. Occurrence information has been compiled from museum records, USFWS data, published and unpublished accounts, environmental impact reports, and field notes of local naturalists. As of August 2001, this database contained over 12,800 records. It should be noted that the species occurrence data represent known records of species observations. Actual presence and distribution of individual species within the MSHCP Area are likely greater than those reflected in the species occurrence database. Therefore, the analysis contained in this EIR/EIS also includes consideration of vegetation community associations for covered species. As noted in later sections of this analysis, impacts to non-covered species are not quantifiable due to the lack of information available for these species.

Considerations in evaluating reserve design and biological function of cores and linkages involve the following general principles of conservation biology:

Conservation of focus species and their habitats throughout the MSHCP Area;
Conservation of large habitat blocks;
Maintenance of habitat diversity;
Contiguity and connectivity of Conservation Areas; and
Protection of Conservation Areas from encroachment and invasion by nonnative species.

Specific considerations in evaluating cores and linkages are based on the discussion of the function of cores and linkages contained in Section 3.1 of the MSHCP. The effects of the various alternatives on identified cores and linkages are based on the configuration of the Conservation Areas proposed under each alternative. The evaluation of impacts to cores and linkages is considered in the report prepared by the California Wilderness Coalition in November 2000. The report identified the location and major threats to wildlife movement corridors throughout the State of California (California Wilderness Coalition, 2000). The report identified 232 linkages within the State, of which 17 are located within the MSHCP Area. As part of this analysis, a review of the 17 linkages was conducted to compare reserve features of the MSHCP to the linkages identified by the California Wilderness Coalition.

The evaluation of impacts related to Covered Activities is based on the inventory of Covered Activities contained in Section 7.0 of the MSHCP. As stated below, it is assumed that the same list of covered activities would apply to all of the plan alternatives.

Consideration of regional resource planning is based on the following existing planning efforts. As shown in Figure 4.1.2, resource conservation planning efforts surrounding the MSHCP Area consist of the following:

(1) San Bernardino Preliminary MSHCP Planning Area. This conservation planning effort is adjacent to the northern border of the MSHCP Area and encompasses approximately 500 square miles containing six unique habitat types, six State endangered or threatened species, 13 federally endangered or threatened species, and over 53 species of special concern. San Bernardino County, through its Natural History Museum staff, has been conducting biological and botanical surveys for the past several years in order to identify habitat needs and requirements for the various sensitive species.

(2) Coachella Valley MSHCP Alternative 2. This conservation planning effort covers the central portion of Riverside County (adjacent to the eastern border of the MSHCP Area) which is the westernmost edge of the Sonoran Desert. The plan area covers 1,136,261 acres, a diverse mixture of desert and mountain habitats and 28 species in the Coachella Valley. The Coachella Valley Association of Governments (CVAG) has prepared an Administrative Review Draft which reflects the work of the Scientific Advisory Committee, the Implementation Subcommittee, and the Project Advisory Group. After receiving comments from the local, State, and federal agencies, a Public Review Draft and Draft EIR/EIS is scheduled for release in 2002.

(3) County of San Diego Multiple Habitat Conservation and Open Space Program (MHCOSP). The MHCOSP is adjacent to the southern border of the MSHCP Area and the eastern border of the San Diego MSCP North County Subarea. The County of San Diego has deferred planning for this subregion until it completes its North County Subarea Plan MSCP amendment.

(4) San Diego Multiple Species Conservation Program (MSCP) North County Subarea. In December 1996, the California Department of Fish and Game (CDFG) and the U.S. Fish and Wildlife Service (USFWS) approved the San Diego MSCP habitat plan that encompasses 582,000 acres and establishes a 172,000-acre preserve system in southwestern San Diego County. This subregional plan covers 85 species of plants and animals and 23 vegetation types. The San Diego MSCP contains the North County Subarea, which is adjacent to the southern border of the Riverside County MSHCP Area and the western border of the MHCOSP County of San Diego. Lands formerly within the Multiple Habitat Conservation Program (MHCP) area have been redefined as the North County Subarea of the San Diego MSCP and will be amended into the MSCP. Additional biological information has been collected, and a science advisory process is underway. A subarea plan is anticipated to be provided for review shortly.

(5) Proposed Orange County Southern Subregion NCCP Planning Area. Orange County and major landowners are preparing a subregional preserve plan (NCCP/HCP) and special area management plan/master streambed alteration agreement that will integrate wetlands and endangered species permits. The Southern Subregion conservation planning effort is adjacent to the southern half of the western border of the MSHCP Area. An update to Orange County's General Plan and Zoning Ordinance is also underway. A public workshop was held in December 2001, to discuss alternatives that should be addressed for each of the three planning efforts in southern Orange County. Currently the Southern Subregion NCCP is in the public scoping process for the EIS/EIR that is anticipated to be provided for public review in the next few months.

(6) Orange County Central-Coastal Subregion NCCP Planning Area. This subregion NCCP borders the northern half of the western border of the MSHCP Area. This conservation plan was approved in July 1996 and establishes a 37,380-acre reserve system that includes significant areas of 12 major habitat types and covers 39 sensitive plant and animal species.

(7) Orange County Northern Subregion. This subregion borders a small portion of the northwestern corner of the MSHCP Area. This subregion is not a part of Orange County's NCCP plan, but a Chevron USA 4(d) permit concurrence letter was issued by the Wildlife Agencies that will allow Chevron to complete oil field abandonment operations in this subregion. The permit also commits Chevron to setting aside and managing a 28-acre preserve area for California gnatcatchers and funding cowbird control efforts.

4.1.2 Assumptions

The analysis of impacts to biological resources of the Proposed Action-MSHCP and the Plan alternatives - is also based on the following assumptions:

109) All of the following policies related to avoiding or reducing biological impacts, which are outlined in the MSHCP, would be incorporated into all of the proposed alternatives, with the exception of the No Project Alternative and the Existing Reserves Alternative:

Wetlands avoidance and minimization (MSHCP, Section 6.1.2);
Narrow endemics survey/conservation requirements (MSHCP, Section 6.1.3);
Additional survey requirements (MSHCP, Section 6.3.2); and
Guidelines pertaining to Urban/Wildlands Interface (MSHCP, Section 6.1.4).

110) With the exception of the No Project Alternative, all of the alternatives are assumed to include Adaptive Management and Monitoring for the species that are covered under each of the respective alternatives consistent with the measures described for those species in Section 5.0 of the MSHCP.

111) Implementation strategy (i.e., Criteria-based plan) is assumed to be the same for all of the alternatives, with the exception of the No Project Alternative and the Existing Reserves Alternative. It is assumed that Criteria would be established for these alternatives that would result in conservation in the same manner as the MSHCP Criteria.

112) Covered activities are assumed to be the same under all of the alternatives with the exception of the No Project Alternative and the Existing Reserves Alternative.

113) Through the MSHCP process, there has been a total of 254 species identified for analysis of potential conservation within the MSHCP Area. This includes the 247 species originally identified by the Wildlife Agencies early in the MSHCP development process, plus seven additional species considered in the planning process. It is assumed that the list of 254 species encompasses all species for which adequate information is available to conduct an analysis under CEQA and NEPA. Analysis of species other than the 254 identified that are not known to exist in the MSHCP Area, have not been identified, or have not been taxonomically distinguished, would involve speculation that is not within the scope of this analysis.

114) For the No Project Alternative, there would be no core/linkage system, no coordinated biological management, and no coordinated strategy for assembling contiguous blocks of reserve lands. Any conservation that would be achieved with the No Project Alternative would result from regulatory requirements imposed upon individual projects.

115) Lands defined as “Public/Quasi-Public” includes lands known to be in public ownership managed for conservation and/or open space value, or land contained in an existing reserve. Assembly of the public/quasi-public lands database revealed that approximately 347,000 acres of public/quasi-public lands are present within the MSHCP Plan Area, including approximately 200,000 acres of lands within the Cleveland or San Bernardino National Forests that are owned by the federal government and managed by the U.S. Forest Service. It is assumed that the same level of conservation and management that is described for the MSHCP would also occur under the other alternatives, with the exception of the No Project Alternative, with the only difference being the focus of management directed at the species covered under each of these alternatives.

116) For the purpose of this analysis, cumulative biological impacts are defined as those impacts resulting from development within the MSHCP Area as a result of build out of the County's and Cities' General Plans, in accordance with SCAG regional growth projections. The term of the MSHCP is proposed to be 75 years, and the MSHCP includes consideration of growth and development within the MSHCP Plan Area for build out of the General Plans. This analysis examines all of the alternatives under a General Plan build out scenario.

Therefore, the analysis of cumulative biological impacts of the Proposed Action and alternatives is assumed to be incorporated into the analysis of the alternatives themselves, since cumulative growth including build out of the General Plans in accordance with SCAG regional growth projections is considered in the MSHCP and the alternatives.

4.1.3 Thresholds of Significance/Criteria for Determining Significance

The following criteria are used to determine whether the Project or the alternatives would have significant impacts on biological resources. The impacts would be significant if implementation of the Project or the alternative being analyzed would:

Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species (including species listed as threatened or endangered) in local or regional plans, policies, or regulations, or by the CDFG or USFWS;
Have a substantial adverse effect on any wetlands or other sensitive natural vegetation community identified in local or regional plans, policies, or regulations or by the California Department of Fish and Game or the United States Fish and Wildlife Service;
Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, impede the use of native wildlife nursery sites, or obstruct genetic flow for identified planning species;
Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan, either within the MSHCP Plan Area or in the surrounding region;
Introduce land use within an area immediately adjacent to the MSHCP Conservation Area that would result in substantial edge effects; or
Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance.

4.1.4 Impacts

MSHCP Proposed Project

Vegetation Communities. For the purposes of this analysis, vegetation types have been grouped into four primary categories: sensitive upland, wetland, forest, and agriculture. Sensitive upland communities include chaparral, coastal sage scrub, desert scrub, grassland (native grassland only, non-native grassland is not a sensitive community), and Riversidean alluvial fan sage scrub vegetation types. Wetland communities include meadows and marshes, playas and vernal pools, water and riparian scrub/woodland/forest vegetation types. Forest communities include montane coniferous forest, peninsular juniper woodland and scrub, and woodlands and forests.

For sensitive upland communities within the MSHCP Area, implementation of the proposed MSHCP would authorize take of 37 percent of chaparral, 48 percent of coastal sage scrub, 66 percent of desert scrub, 72 percent of grassland (including both native and non-native grassland), and 34 percent of Riversidean alluvial fan sage scrub (Table 4A).

For wetland communities within the MSHCP Area, the proposed MSHCP would authorize take of 76 percent of meadows and marshes, 15 percent of playas and vernal pools, 15 percent of water, and 26 percent of riparian scrub/woodland/forest. For forest communities within the MSHCP Area, the proposed MSHCP would authorize take of 31 percent of montane coniferous forest, and 32 percent of woodlands and forests. In addition, 88 percent of the agricultural land in the Plan Area would be authorized for take under the proposed MSHCP, as it would be outside the MSHCP Conservation Area and could be used for agricultural activities.

Source: Western Riverside County MSHCP, November 2002.

Certain features incorporated in the MSHCP would minimize to the extent feasible potential impacts to sensitive vegetation communities. These include assembly of an approximately 500,000-acre MSHCP Conservation Area encompassing Conserved Habitat. Conserved Habitat is defined as land that is permanently protected and managed for the benefit of the Covered Species with the Proposed Action under legal arrangements that prevent its conversion to other uses. The acreages of vegetation communities not authorized for take would be included as Conserved Habitat within the MSHCP Conservation Area. For example, while 31 percent of the montane coniferous forest would be in the take authorized area for the Proposed Action, 69 percent of the montane coniferous forest would be included in the MSHCP Conservation Area as Conserved Habitat. In general, inclusion of the majority of the forest communities as Conserved Habitat within the MSHCP Conservation Area would not result in a substantial reduction of these communities, therefore impacts are considered to be less than significant.

For the sensitive upland communities, inclusion of 63 percent of the chaparral within the MSHCP Conservation Area would not result in a substantial reduction of these communities given the large percentage of this vegetation community to be included as Conserved Habitat with the Proposed Action, the extensive acreage and wide distribution of this vegetation community in the Plan Area, and the relatively low numbers of listed species preferring this vegetation community within the Plan Area. For coastal sage scrub and Riversidean alluvial fan sage scrub, although 52 percent and 66 percent of these vegetation communities, respectively, would be included as Conserved Habitat, substantial impacts to coastal sage scrub and Riversidean alluvial fan sage scrub would remain due to the patchy distribution of these vegetation communities in the Plan Area and the relatively large numbers of sensitive species occurring in these vegetation communities. However, features incorporated into the proposed project, including the configuration of conserved lands, as well as adaptive management and monitoring, would reduce this impact to a less than significant level. The Project would reduce grassland (including native and non-native grassland) and desert scrub by 72 percent and 66 percent, respectively. Features incorporated into the proposed Plan, including the configuration of conserved lands, as well as adaptive management and monitoring, would reduce impacts to desert scrub to a less than significant level. However, as the vegetation coverage does not distinguish between native and non-native grassland, impacts to sensitive native grassland cannot be quantified independently, and significant impacts to this vegetation community may still occur.

With respect to agriculture, the Project and its associated take authorization could result in impacts to 88 percent of this vegetation community. However, agriculture is not a sensitive natural vegetation community. Thus, impacts to agriculture are not regarded as biologically significant. (For analysis of whether the Project and the alternatives will have significant impacts on agriculture, see Section 4.2. Impacts to species that utilize agricultural lands are discussed below in Impacts to Listed Covered Species and Impacts to Non-Listed Covered Species.)

Section 6.1.2 of the MSHCP discusses mapping of riparian, riverine, vernal pools, and other potentially jurisdictional wetland areas as part of the CEQA review of applications for Covered Activities within the MSHCP Plan Area. The policy calls for avoidance and minimization of impacts to wetland habitat throughout the Plan Area in accordance with existing regulatory standards that call for conservation and mitigation of wetland functions and values. Together, inclusion of substantial acreages of wetland vegetation communities within the MSHCP Conservation Area, and implementation of the Riparian/Riverine/Vernal Pool policy incorporated in the MSHCP, would reduce identified impacts to wetland vegetation communities to a level below significance. Thus implementation of the MSHCP will not have a substantial adverse impact on any wetland or other sensitive natural community identified in local or regional plans, policies, or regulations or by the Wildlife Agencies.

Listed Covered Species. The proposed MSHCP Conservation Area encompasses approximately 500,000 acres, comprising 347,000 acres of public/quasi-public land and 153,000 acres of Additional Reserve Lands and conserves portions of all vegetation communities distributed throughout the MSHCP Plan Area. Representative vegetation communities from the seven bioregions in the Plan Area are conserved with the Proposed Action. No developed areas or disturbed habitats are proposed for conservation.

The MSHCP provides take authorization for covered species resulting from Covered Activities outside of the Criteria Area, as well as those Covered Activities that are consistent with the Criteria and permitted inside the Criteria Area. In addition, coverage is provided for certain activities within the Criteria Area and within existing public/quasi-public lands, including maintenance and minor improvements to existing roads, improvements related to planned roads, and limited future facilities, such as electrical, gas, water, sewer, flood control, and State Park facilities.

The MSHCP includes specific criteria for locating such facilities and provides guidelines for design of the facilities that would avoid or reduce impacts. The best available information has been used to include a quantitative analysis of the impacts from these facilities, which is included in the impacts associated with the Plan as a whole, as presented in Table 4A. It should be noted, however, that existing and future roadways within the Criteria Area, including General Plan Circulation Element Roads, CETAP facilities, and Caltrans facilities would not be included in the total acreage considered for conservation within the MSHCP Conservation Area.

As a result of issuance of the proposed 10(a) permit, the species identified in Table 4B could be legally taken by permitted jurisdictions where they occur outside of the MSHCP Conservation Area. Nineteen of the 83 covered wildlife species and 13 of the 63 covered plant species are listed under FESA or CESA. These 19 wildlife species and 13 plant species will be directly affected by the Plan because they will no longer receive protection outside of the MSHCP Conservation Area. The impacts to the 32 Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Listed Covered Species (Table 4B). These impacts vary depending on the species. For example, as shown in Table 4B, implementation of the proposed take authorization would result in the potential direct loss of 45 percent of suitable habitat for the coastal California gnatcatcher. For vernal pool fairy shrimp, approximately 12 percent of suitable habitat occurring outside of the MSHCP Conservation Area would be directly affected, and no known localities would be affected.

Features have been incorporated in the MSHCP to minimize impacts to Listed Covered Species to the extent feasible. These include assembly of an MSHCP Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of coastal California gnatcatcher at Alberhill, North Peak, Kabian Park, and Ramsgate would be conserved, as well as linkages, such as the Sedco Hills and Gavilan Plateau, to other localities in the MSHCP Area. Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Strategy, and other implementation strategies as described in Section 6.1.1, MSHCP, Volume I.

In addition, the proposed MSHCP includes policies that would afford additional protection to some Listed Covered Species occurring outside of the MSHCP Conservation Area. The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Narrow Endemic Plant Species Policy

Munz's onion
San Diego ambrosia
San Jacinto Valley crownscale
Nevin's barberry
thread-leaved brodiaea

Vail Lake ceanothus
slender-horned spine flower
spreading navarretia
California Orcutt grass

Additional Survey Needs Policy

western yellow-billed cuckoo
southwestern willow flycatcher

least Bell's vireo
San Bernardino kangaroo rat

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that is consistent with the conservation objectives for individual species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas described in Section 6.1.2 of the MSHCP, Volume I. As part of this policy, survey, mapping, and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For areas containing riparian, riverine, or vernal pool features that are located outside of the MSHCP Conservation Area, avoidance and minimization measures, as required as mitigation through the CEQA process or State/federal regulatory processes, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting Listed Covered Species. The following Listed Covered Species would benefit from implementation of the wetland policy.

Listed Covered Wetland Species

vernal pool fairy shrimp
Riverside fairy shrimp
Santa Ana sucker
arroyo toad
California red-legged frog
mountain yellow-legged frog
western yellow-billed cuckoo
southwestern willow flycatcher

peregrine falcon
bald eagle
least Bell's vireo
California Orcutt grass
San Jacinto Valley crownscale
thread-leaved brodiaea
San Diego button-celery
spreading navarretia

If suitable habitat were determined to be present, focused surveys for the following Listed Covered Species would be conducted: least Bell's vireo, southwestern willow flycatcher, western yellow-billed cuckoo, vernal pool fairy shrimp, and Riverside fairy shrimp. Localities of wetland species observed during focused surveys would be conserved in accordance with the process of wetland conservation identified in Section 6.1.2 of the MSHCP.

Additional covered activities inside the Criteria Area that are considered to be allowable uses within the MSHCP Conservation Area but have not been included in the quantification of impacts contained in Table 4A are the allowances for development of single-family homes on existing legal parcels within the Criteria Area and the possible allowance of agricultural conversion on lands within the Criteria Area up to a maximum of 10,000 acres.

Development of individual single-family homes on existing legal parcels (hereinafter referred to as the “Single-Family Home Expedite Process”), in accordance with existing land use regulations, is a covered activity within the Criteria Area. An expedited review process, through the Property Owner Initiated Habitat Evaluation and Acquisition Negotiation Process has been developed as part of the MSHCP to assist in determining the appropriate location of a single-family home or mobile home on an existing legal lot within the Criteria Area.

If during the review period it is determined that all or part of the property may benefit the assembly of the MSHCP Conservation Area, the Permittee may negotiate with the property owner to acquire the entire lot or portion thereof or determine which incentives may apply in order to acquire a conservation easement over that portion of the property that is not necessary for access road(s) and outside of the building footprint area. If the Permittee is unable to reach agreement with the property owner concerning the acquisition of the entire lot or a conservation easement over a portion of the lot upon completion of the review period, the property owner may proceed with the processing of the grading or site preparation permit application. However, compliance with the location of the building footprint area as well as the location of any necessary road(s) will be required.

Trend data collected from 1995 to mid 2002 suggests that, on average, there is development of approximately 75 single-family homes on lots averaging approximately 9 acres in size within the Criteria Area on an annual basis. Therefore, the Single-Family Home Expedite Process will have the potential to affect approximately 675 acres of land within the Criteria Area annually. For the purpose of this analysis, it is assumed that approximately 50 percent of that area, or 338 acres, potentially within the area subject to take authorization by such development will be within areas of sensitive habitat that are considered desirable for inclusion in the Reserve. This is based on the overall ratio of Additional Reserve Lands to Criteria Area, which is roughly one half. Based on the trend data and average parcel size, that 338 acres represents approximately 38 parcels. It is estimated that the Permittees will be able to successfully negotiate with 75 percent, or 29 of the 38 property owners through the Property Owner Initiated Habitat Evaluation and Acquisition Negotiation Process. Therefore, it is assumed that conservation that conforms to the Criteria will be achieved on approximately 253 of the 338 acres of land per year that is potentially within the area subject to take authorization through this process. It is assumed that the remaining approximately 85 acres will not be developed in accordance with the Criteria and will become unavailable for conservation on an annual basis, as a result of the Single-Family Home Expedite Process.

The inability to incorporate into the Reserve approximately 85 acres of land that is desirable for conservation throughout the Plan Area on an annual basis will not reduce the overall acreage required for Additional Reserve Lands. So while conservation may be precluded on an estimated average of 85 acres per year, it is not expected that this will adversely affect the ability to assemble a viable MSHCP Conservation Area, since there is adequate additional land within the Criteria Area that could be acquired in lieu of the areas subject to development under the Single-Family Home Expedite Process.

In addition, annual reporting will determine whether the activity of single-family home development occurs in a manner that is consistent with the assumptions used for the MSHCP analysis. The number of grading or site preparation permits for the construction or location of a single-family home or a mobile home on an existing legal lot located within the Criteria Area will be monitored and reported on at least an annual basis in order to insure that appropriate assembly of the MSHCP Conservation Area is occurring. Therefore, no significant impacts on Covered Species will result from the construction or location or single-family or mobile homes on existing legal lots within the Criteria Area.

If Section 6.3 of the MSHCP is implemented, conversion of natural lands to agricultural use, as defined and outlined in that section of the MSHCP, will be allowed as a covered activity within the Criteria Area, up to an established threshold of 10,000 acres over the life of the plan ( the “New Agricultural Lands Cap”). Agricultural Operations, as defined in Section 6.3 of the MSHCP, include all uses conducted as a normal part of such operations, provided such actions are in compliance with all applicable laws and regulations.

To verify the location of the existing Agricultural Operations, the County will establish a database identifying existing Agricultural Operations (“Existing Agricultural Operations Database”) on or before the effective date of the Implementing Agreement or the issuance of the Section 10(a) Permit and the NCCP Authorization. The new Agricultural Lands Cap of 10,000 acres within the Criteria Area will be applied to Agricultural Operations that are in addition to the activities recorded in the Existing Agricultural Operations Database. The 10,000-acre New Agricultural Lands Cap represents approximately 3 percent of the total acreage that is contained within the Criteria Area.

To estimate the potential effects of New Agricultural Lands in relation to the MSHCP, it is assumed that approximately 50 percent of the agricultural conversions that take place within the Criteria Area will be consistent with the Criteria. Therefore, it is assumed that approximately 5,000 acres of New Agricultural Lands will occur within areas considered desirable for conservation under the Criteria. This represents approximately 1.5 percent of the total Additional Reserve Lands proposed to be acquired within the Criteria Area. Tracking of MSHCP implementation, and adjustments to Reserve Assembly strategies as outlined in this section, will provide a mechanism to ensure that adequate acreage of Additional Reserve Lands is being acquired, and that appropriate reserve design and configuration are being achieved. Therefore, no significant biological impacts to Listed Covered Species are anticipated to result from New Agricultural Lands Cap.

With the combination of impact reduction features incorporated into the Proposed Project, including reserve configuration, adaptive management and monitoring, and species survey and avoidance/minimization policies, the Project's impacts to Listed Covered Species would be less than significant.

Non-Listed Covered Species. The Non-Listed Covered Species include 65 of the 83 covered wildlife species and 52 of 63 plant species. The impacts to the 115 Non-Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Non-Listed Covered Species (Table 4C). These impacts vary depending on the species. For example, as shown on Table 4C, implementation of the proposed take authorization would result in take authorization for 75 percent of suitable habitat for the burrowing owl. For Santa Rosa Plateau pool fairy shrimp, approximately 15 percent of suitable habitat occurring outside of the MSHCP Conservation Area would be within the area subject to take authorization. For certain Non-Listed Covered Species, such as arroyo chub and San Bernardino flying

Source: October 2000 MSHCP Alternatives Development Document.

Features have been incorporated in the MSHCP to minimize impacts to Non-Listed Covered Species. These include assembly of an MSHCP Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of Bell's sage sparrow at Lake Skinner/Diamond Valley Lake, Aguanga, and the Jurupa Mountains, would be conserved, as well as linkages, such as the Sedco Hills and Hogbacks, to other localities in the MSHCP Plan Area. The Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Process described in Section 6.1.1, MSHCP, Volume I.

The direct and indirect impacts of Covered Activities on Non-Listed Covered Species would be the same as for Listed Covered Species.

In addition, the proposed MSHCP includes policies that would afford some additional protection to Non-Listed Covered Species occurring outside of the MSHCP Conserva-tion Area. The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Non-Listed Covered Species are subject to the narrow endemic plant species policy and additional survey needs policy.

Narrow Endemic Plant Species Policy

Yucaipa onion
Johnston's rock-cress
Munz's mariposa lily
many-stemmed dudleya
San Jacinto Mountains bedstraw

Brand's phacelia
San Miguel savory
Hammitt's clay-cress
Wright's trichocoronis

Additional Survey Needs Policy

burrowing owl
Aguanga kangaroo rat
Los Angeles pocket mouse
smooth tarplant

Coulter's goldfields
little mousetail
Parish's brittlescale
Nevin's barberry

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information-gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that is consistent with the conservation objectives for individual species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of this policy, survey, mapping, and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests and other habitat types, known to occur in the Plan Area. For areas containing riparian, riverine, and vernal pool features that are located outside of the MSHCP Conservation Area, wetlands avoidance and minimization measures, required as mitigation through the CEQA process or State/Federal regulatory processes, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting a number of Non-Listed Covered Species, including 10 plant species and 22 wildlife species. The following Non-Listed Covered Species would benefit from implementation of this policy.

Non-Listed Covered Wetland Species

coast range newt
western spadefoot
western pond turtle
American bittern
Lincoln's sparrow breeding
Macgillivray's warbler
Nashville warbler

California spine flower
Coulter's goldfields
Davidson's saltscale
little mousetail
Orcutt's brodiaea
Parish's brittlescale
Parish's meadowfoam
vernal barley
Wright's trichocoronis

If suitable habitat were determined to be present, focused surveys for the Santa Rosa Plateau fairy shrimp would be conducted. Localities of wetland species observed during focused surveys would be conserved in accordance with wetland conservation policies described in Section 6.1.2 of the MSHCP.

With the combination of impact-reduction features incorporated into the proposed project, including reserve configuration adaptive management and monitoring, and species survey and avoidance/minimization policies, impacts to Non-Listed Covered Species would be less than significant.

Non-Covered Species. The list of species that receive coverage under the MSHCP is in part the result of previous analyses conducted by USFWS in their preparation of Tables 1 and 2 included in an August 9, 1999 Draft Proposal for the MSHCP (DUDEK & Associates, 1999). Table 1 of the August 9, 1999 Draft Proposal formed the basis for the initial species list to be considered for conservation in the MSHCP and Table 2 represented the list of species for which additional information was still needed to fully consider the species for conservation.

Together, Tables 1 and 2 identified 247 species for consideration in the MSHCP, and 8 additional species were added to the list under consideration. Through the MSHCP process, a total of 255 species were identified as having the potential to exist within the MSHCP area. Upon the completion of additional analyses and literature reviews by DUDEK and the Wildlife Agencies with respect to species accounts, the final list of Covered Species was narrowed to 146 species. The list of 255 species encompasses all species for which adequate information is available to conduct an impact analysis under CEQA and NEPA. Analysis of species other than the 255 identified would involve speculation that is not required by CEQA or NEPA.

Of these 255 species, it has been determined that the MSHCP will not include 109 of these species as Covered Species. Table 4D includes a list of these 109 species, including an explanation of why the species were not included as Covered Species under the MSHCP. While it is assumed that the conservation provided under the MSHCP could potentially benefit Non-Covered Species that occur within the MSHCP Conservation Area, it is not possible to quantify the level of conservation because of the lack of information available for these species or because the species are not known to occur within the MSHCP Area. The features of the MSHCP that would contribute to the conservation of non-covered species would include maintenance of cores and linkages and impact avoidance and minimization policies. In addition, mitigation of adverse effects offered through the Adaptive Management and Monitoring Programs would provide overall benefits to habitats that could result in a certain level of conservation for non-covered species. However, even with these benefits offered by the Proposed Plan, because of the lack of information available to plan adequately for conservation of these species, impacts, including impacts resulting from Covered Activities, are assumed to be potentially significant and not mitigable.

Cores and Linkages. As described in the Proposed Plan, the MSHCP Conservation Area comprises a variety of existing and proposed cores, extensions of existing cores, linkages, constrained linkages, and non-contiguous habitat blocks. These features, generally referenced as cores and linkages, are depicted in Figure 4.1.3. The following is a summary of definitions that apply to the legend items shown in Figure 4.1.3.

Core	A block of habitat of appropriate size, configuration, and vegetation characteristics to generally support the life history requirements of one or more Covered Species. Although a more typicaldefinition is population-related and refers to a single species(Hunter, 2002; Primack, 2000), in the MSHCP this term is habitat-related because of the multi-species nature of the Proposed Plan.
Extension of Existing Core	A block of habitat contiguous with an existing core area, which serves to provide additional habitat for species in the adjacent existing core and to reduce exposed edge.
Non-contiguous Habitat Block	A block of habitat not connected to other habitat areas via a linkage or constrained linkage.
Constrained Linkage	A constricted connection expected to provide for movement of identified Planning Species between core areas, where options for assembly of the connection are limited due to existing patterns of use.
Linkage	A connection between core areas with adequate size, configuration and vegetation characteristics to generally provide for “live-in” habitat and/or provide for genetic flow for identified Planning Species. Areas identified as linkages in the Proposed MSHCP may provide movement habitat but not live-in habitat for some species, thereby functioning more as movement corridors. Since it is expected that every linkage will provide live-in habitat for at least one species, and since the term “corridor” may be easily confused with the term as it is applied to transportation corridors discussed in the CETAP portion of the RCIP, the term linkage is used here. For a more thorough discussion of linkage and movement corridors, see Section 3.1.4 of the MSHCP Project, Applicable Conservation Biology Principles.

As shown in Table 4E, all of the cores and linkages depicted in Figure 4.1.3 would be incorporated in the MSHCP Conservation Area under the Proposed MSHCP. As noted in the discussion of the Relationship to Adopted or Approved HCPs and NCCPs, these cores and linkages include all the missing links identified in the California Wilderness Coalition Report for cores and linkages in the South Coast Ecoregion. Certain links (like the link from Palomar Mountains to Santa Ana Mountains) include locations not within the MSHCP Area or involve lands that are not a part of the MSHCP. For example, the Palomar Mountains to Santa Ana Mountains linkage includes lands in San Diego County and American Indian Lands that are not a part of the MSHCP. MSHCP is contributing cores and linkages within additional Reserve Lands. Chapter 3 of the Draft MSHCP identifies the distance between existing cores.

The proposed Plan provides for the movement of native resident and migratory species and protects established wildlife corridors and genetic flow. The Plan also protects the use of native wildlife nursery sites. Therefore, impacts related to cores and linkages resulting from the Plan are considered to be less than significant.

Relationship to Adopted or Approved HCPs or NCCPs. As shown in Figure 4.1.2, Regional MSHCP Context, the Additional Reserve Lands and existing public/quasipublic lands do not conflict with the provisions of any adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan, either within the MSHCP Plan Area or in the surrounding region. Rather, the MSHCP will complement other regional planning efforts, including those that are currently underway but have not yet been approved.

The discussion below describes the public and private lands that will provide connection to regional conservation planning adjacent to the MSHCP Area in the different alternative scenarios, and the extent to which the MSHCP will incorporate the missing linkages in the South Coast Ecoregion described in the California Wilderness Coalition Report.

San Bernardino Preliminary MSHCP Planning Area. The northern border of the Plan Area will continue to provide conservation planning in the Santa Ana River and the San Bernardino National Forest (Existing Cores A and I, respectively). In addition to those existing cores, Proposed Linkages 6, 5, and 4, and Proposed Noncontiguous Habitat Blocks 1, 2, and 3 are proposed in the northern border of the Plan Area. These existing and proposed cores and linkages provide connection to the San Bernardino Preliminary MSHCP Planning Area to the North.

Coachella Valley MSHCP Alternative 2. In the eastern border of the MSHCP Area, connection to the Coachella Valley MSHCP Alternative 2 is provided through San Bernardino National Forest and Anza-Borrego Desert State Park (Existing cores K and L, respectively).

San Diego MSCP North County Subarea and MHCOSP. Beauty Mountain Management Area (BLM land), Agua Tibia Mountain Wilderness Area, Santa Margarita Ecological Reserve, and the Cleveland National Forest will continue to be managed for biological resources and will provide connection to the MHCOSP and San Diego MSCP North County Subarea to the south of the MSHCP Area (Existing Cores L, M, G, and B, respectively). A parcel of BLM-owned land (Existing Linkage A), may be used to move from Pechanga Creek south into San Diego County, and Proposed Core 7 will also provide connection south into the MHCOSP through a mosaic of upland and wetland habitat. Proposed Constrained Linkages 9, 10, 11, and 12 connect the Santa Rosa Plateau and Tenaja Corridor to San Diego MSCP North County Subarea to the south, and Proposed Linkage 9 will also provide connection to the Cleveland National Forest in San Diego County.

Orange County Proposed Southern, and Central and Coastal Subregion NCCP Planning Area. The MSHCP provides connection into the Southern and Central and Coastal Subregion NCCP Planning Areas to the west through the Cleveland National Forest (Existing Core B). However, in the southwestern corner of the MSHCP Area is a small piece of land designated as “rural mountainous” surrounded by Cleveland National Forest to the north and east, with the proposed Orange County Southern Subregion NCCP Planning Area to the west. This small piece of land is not proposed to be part of the MSHCP Additional Reserve Lands and does not provide connection to surrounding regional conservation planning. As the Orange County Southern Subregion NCCP is developed, the location of this land should be taken in to account by all affected planning agencies.

Missing Linkages in the California Wilderness Coalition Report. The Proposed MSHCP has incorporated the missing linkages identified in the California Wilderness Coalition Report.

Edge Effects. An edge effect is defined as a change in the “conditions or species composition within an otherwise uniform habitat as one approaches a boundary with a different habitat” (Ricklefs, 1993). Edge effects at the boundary between natural lands and human-occupied lands (“urban edge effects”) arise due to human-related intrusions such as lighting, noise, invasive species, exotic predators (e.g., dogs, cats, and opossums), hunting, trapping, off-road activities, dumping, and other forms of recreation and disturbance. Although some species are in some ways unaffected by edges -- for example, reproductive output of the rufous-crowned sparrow (Morrison and Bolger, 2002), distribution of arthropod species (Bolger, et al., 2000) - or even show preferences for edges - for example, indigo buntings and northern cardinals in Woodward, et al. (2001) - human-induced edge effects are generally unfavorable to native species.

Edge effects could occur to species and habitats within the MSHCP Conservation Area if proposed land uses and activities in take authorized areas occur in proximity to the MSHCP Conservation Area. Edge effects may be short-term effects related to construction or long-term effects associated with development or land use practices in proximity to Conserved Habitat areas. For the Proposed Action, it is assumed that edge effects resulting from construction activities include dust, noise, and general human It is assumed that edge effects resulting from development or land use practices in proximity to Conserved Habitat areas include long-term presence of unshielded noise-generating land uses in proximity to the MSHCP Conservation Area; unshielded night-lighting directed within the MSHCP Conservation Area; use of exotic landscape plant materials that may invade native vegetation communities within the MSHCP Conservation Area; discharge of uncontrolled or unfiltered urban runoff toward the MSHCP Conservation Area, including potential toxics; and uncontrolled access, dumping or trespass within the MSHCP Conservation Area.

For those cores and linkages with higher perimeter-to-area ratios, as identified in Table 4E, edge effects would be considered to have a greater effect on Conserved Habitat and Covered Species than for the larger cores and linkages incorporated in the MSHCP Conservation Area.

As noted in the discussions of Impacts to cores and linkages and Impacts Related to Covered Activities, a variety of features have been incorporated into the proposed MSHCP that will minimize edge effects. These include the following:

Implementation of standard BMPs (Appendix C of the MSHCP);
Implementation of the Land Use Guidelines Pertaining to the Urban/Wildlands Interface (Section 6.1.4 of the MSHCP); and
Implementation of the siting, design, construction, operations, and maintenance guidelines for Covered Activities within the Criteria Area and Allowable Uses within the MSHCP Conservation Area (Section 7.0 of the MSHCP).

With these features incorporated, the MSHCP's edge effects are less than significant.

Listed, Proposed, and Strong Candidate Species Alternative

Vegetation Communities. For sensitive upland communities within the MSHCP Area, implementation of this alternative would authorize take of 43 percent of the chaparral, 53 percent of the coastal sage scrub, 90 percent of the desert scrub, 75 percent of the grassland (including native and non-native grassland), and 44 percent of the Riversidean alluvial fan sage scrub (Table 4F). For wetland communities within the MSHCP Area, this alternative would authorize take of 81 percent of the meadows and marshes, 26 percent of the playas and vernal pools, 17 percent of water, and 38 percent of the riparian scrub, woodland and forest. For forest communities within the MSHCP Area, this alternative would authorize take of 31 percent of the montane coniferous forest, and 35 percent of the woodlands and forests. In addition, 84 percent of the agricultural land in the Plan Area would be authorized for take by implementation of this alternative.

Notes: 1 Impacts associated with the No Project Alternative are presented separately. 2 Includes cismontane alkali marsh. 3 Totals exclude developed/disturbed land, because no additional impact to biological resources would occur in these areas as a result of implementation of the Proposed MSHCP or alternatives. Source: Western Riverside County MSHCP, November 2002.

Certain features incorporated in the MSHCP would minimize impacts to sensitive vegetation communities. These include assembly of an approximately 477,000-acre MSHCP Conservation Area encompassing Conserved Habitat. Conserved Habitat is defined as land that is permanently protected and managed for the benefit of the Covered Species under this alternative under legal arrangements that prevent its conversion to other uses. The acreages of vegetation communities not authorized for take under this alternative would be included as Conserved Habitat within the MSHCP Conservation Area. For the sensitive upland communities, inclusion of 57 percent of the chaparral within the MSHCP Conservation Area under this alternative would reduce identified impacts to these communities to a level below significance given the large percentage of this vegetation community to be included as Conserved Habitat under this alternative, the extensive acreage and wide distribution of this vegetation community in the Plan Area, and the relatively low numbers of listed species preferring this vegetation community within the Plan Area. For Riversidean alluvial fan sage scrub, although 56 percent of this vegetation community would be included as Conserved Habitat under this alternative, significant impacts to Riversidean alluvial fan sage scrub would remain due to the patchy distribution of this vegetation community in the Plan Area and the relatively large numbers of sensitive species occurring in this vegetation community. Due to the large percentages of coastal sage scrub (53%), grassland (75%) (including native and non-native grassland), and desert scrub (90%) potentially within the area subject to take authorization within the take authorized area under this alternative, significant impacts to these vegetation communities would occur even with application of the minimization measures. With respect to agriculture, although the proposed take authorization under this alternative would apply to 84 percent of this vegetation community, this vegetation community is not a sensitive natural community, so impacts to agriculture are not considered biologically significant. (As noted previously, impacts to agriculture are analyzed in Section 4.2, and impacts to species that utilize agricultural lands have been analyzed in the discussions of impacts to Listed Covered Species and impacts to Non-Listed Covered Species.)

In addition, Section 6.1.2 of the MSHCP discusses mapping of riparian, riverine, vernal pools, and other potentially jurisdictional wetland areas as part of review of applications for Covered Activities within the MSHCP Area. The policy calls for avoidance and minimization of impacts to wetland habitat throughout the Plan Area in accordance with existing regulatory standards that call for no net loss of wetland functions and values. Together, inclusion of substantial acreages of wetland vegetation communities within the MSHCP Conservation Area under this alternative, and implementation of the policy related to riparian, riverine, and vernal pool areas incorporated in the MSHCP, would reduce identified impacts to wetland vegetation communities to a level below significance.

Listed Covered Species. The Listed, Proposed, and Strong Candidate Species Alternative encompasses approximately 466,000 acres, comprising 347,000 acres of public/quasipublic land and 119,000 acres of Additional Reserve Lands, and conserves portions of all vegetation communities distributed throughout the MSHCP Area. Representative vegetation communities from the seven bioregions in the Plan Area are conserved under this scenario. None of the land cover types identified on the vegetation map as developed or disturbed are proposed for conservation.

As a result of issuance of a 10(a) permit, the listed species identified in Table 4B could be legally taken by permitted jurisdictions where they occur outside of the MSHCP Conservation Area. The list of Listed Covered Species for this alternative is the same as for the MSHCP Project. The Listed Covered Species would be directly affected by the take authorization because they will no longer receive protection outside of the MSHCP Conservation Area. The impacts to the 32 Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Listed Covered Species (Table 4B).

Covered activities under this alternative would be identical to those described for the MSHCP. Therefore, the impacts to Listed Covered Species associated with Covered Activities, including development of single-family homes or location of mobile homes on existing legal parcels and conversion of natural lands to agricultural use (as defined However, the impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP. For example, loss of suitable habitat for southwestern willow flycatcher would be 4,735 acres (34%) under this alternative, and the loss of suitable habitat under the proposed MSHCP would be approximately 3,220 acres (23%) (Table 4B). For certain Listed Covered Species, such as Delhi Sands flower-loving fly and Munz's onion, the precise quantity of the impact is undetermined at this time due to lack of existing available information regarding these species.

Features are incorporated into the Listed, Proposed, and Strong Candidate Species Alternative to minimize impacts to Listed Covered Species. These include assembly of an MSHCP Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of coastal California gnatcatcher at Alberhill, North Peak, Kabian Park, and Ramsgate would be conserved, as well as linkages, such as the Sedco Hills and Gavilan Plateau, to other localities in the MSHCP Area. Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Process described in Section 6.1.1, MSHCP, Volume I.

In addition, this alternative includes policies that would afford some Listed Covered Species occurring outside of the MSHCP Conservation Area additional protection. The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Narrow Endemic Plant Species Policy

Munz's onion
San Diego ambrosia
San Jacinto Valley crownscale
Nevin's barberry
thread-leaved brodiaea

Vail Lake ceanothus
slender-horned spine flower
spreading navarretia
California Orcutt grass

Additional Survey Needs Policy

western yellow-billed cuckoo
southwestern willow flycatcher

least Bell's vireo
San Bernardino kangaroo rat

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that provides for long-term conservation of these species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of the wetland policy, survey, mapping and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For mapped resources that are located outside of the MSHCP Conservation Area, wetlands avoidance and minimization measures, consistent with existing regulations, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting Listed Covered Species. The following Listed Covered Species would benefit from implementation of the policy related to riparian, riverine, and vernal pool areas.

Listed Covered Wetland Species

vernal pool fairy shrimp
Riverside fairy shrimp
Santa Ana sucker
arroyo toad
California red-legged frog
mountain yellow-legged frog
western yellow-billed cuckoo
southwestern willow flycatcher

peregrine falcon
bald eagle
least Bell's vireo
California Orcutt grass
San Jacinto Valley crownscale
thread-leaved brodiaea
San Diego button-celery
spreading navarretia

If suitable habitat were determined to be present, focused surveys for the following Listed Covered Species would be conducted: least Bell's vireo, southwestern willow flycatcher, western yellow-billed cuckoo, vernal pool fairy shrimp, and Riverside fairy shrimp. Localities of wetland species observed during focused surveys would be conserved in accordance with wetland conservation policies contained in Section 6.1.2 of the MSHCP.

A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, Anza Valley, Badlands, and Reche Canyon is anticipated under this alternative. Areas such as the Jurupa Mountain, Cactus Valley, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area, would be excluded under this alternative. However, with application of the narrow endemic policy, additional survey needs policy and wetlands policy, as well as reserve assembly and configuration, direct and indirect impacts to Listed Covered Species would be reduced to less than significant levels.

Non-listed Covered Species. Implementation of the Listed, Proposed, and Strong Candidate Species Alternative would result in direct and indirect impacts to Non-Listed Covered Species. The Non-Listed Covered Species for the Listed, Proposed and Strong Candidate Species Alternative include those species identified in Table 4G.

The species identified in Table 4G could be legally taken by permitted jurisdictions where they occur outside of the MSHCP Conservation Area. The impacts to the Non-Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Non-Listed Covered Species (the analysis summary for these species is contained in Table 4C).

Covered activities under this alternative would be identical to those described for the MSHCP. Therefore, the impacts to Non-Listed Covered Species associated with Covered Activities, including development of single-family homes or location of mobile homes on existing legal parcels and conversion of natural lands to agricultural use (as defined and outlined in Section 6.3 of the MSHCP, if implemented) within the Criteria Area, are the same as they are for the MSHCP.

The impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP. For example, loss of suitable habitat for yellow-breasted chat would be 4,085 acres (33%) under this alternative, and the loss of suitable habitat under the proposed MSHCP would be approximately 2,780 acres (22%) (Table 4C). For certain Non-Listed Covered Species, such as arroyo chub and San Bernardino flying squirrel, the precise quantification of the impact is undetermined at this time due to lack of existing available information regarding these species.

Features are incorporated into the Listed, Proposed, and Strong Candidate Species Alternative to minimize impacts to Non-Listed Covered Species. These include assembly of an MSHCP Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of Bell's sage sparrow at Lake Skinner/Diamond Valley Lake, Aguanga, and the Jurupa Mountains, would be conserved, as well as linkages, such as the Sedco Hills and Hogbacks, to other localities in the Plan Area. Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Process described in Section 6.1.1, MSHCP, Volume I.

In addition, this alternative includes policies that would afford some Non-Listed Covered Species occurring outside of the MSHCP Conservation Area additional protection. The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Non-Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that provides for long-term conservation of these species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of this policy, survey, mapping and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code and Sections 401, 402, and 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For mapped habitat located outside of the MSHCP Conservation Area, avoidance and minimization measures, consistent with existing regulations, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting a number of Non-Listed Covered Species. The following Non-Listed Covered Species would benefit from implementation of this policy.

A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, Anza Valley, Badlands, and Reche Canyon is anticipated under this alternative. Areas such as the Jurupa Mountain, Cactus Valley, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area, would be excluded under this alternative. However, adequate conservation for the Non-Listed Covered Species is provided with this alternative. It should be noted that certain species that are covered under the MSHCP Project are not covered under this alternative.

Non-Covered Species. The list of defined Non-Covered Species for the Listed, Proposed, and Strong Candidate Species Alternative is presented in Table 4H. Any conservation benefits that would accrue to these species as a result of the MSHCP project would be reduced under this alternative, due to the reduction in overall Conservation Area. However, as noted, it is not possible to fully quantify the potential adverse effects to Non-Covered Species at this time due to the lack of information for these species. Please also refer to discussion of impacts to non-covered species for the proposed MSHCP. Impacts to non-covered species, including impacts resulting from Covered Activities, are therefore assumed to be potentially significant and not mitigable.

Cores and Linkages. Under the Listed, Proposed, and Strong Candidate Species Alternative, all of the cores and linkages noted in Table 4E for this alternative would be incorporated into the MSHCP Conservation Area. As noted in the discussion of the Relationship to Adopted or Approved HCPs and NCCPS, these cores and linkages include most but not all of the missing links identified by the California Wilderness Coalition in its study of linkage priorities in the South Coast Ecoregion, for which the MSHCP has the ability to incorporate such cores and linkages. Table 4E also identifies the proposed cores and linkages that are not included as part of this alternative. Most notable is the exclusion of the constrained linkages from French Valley to Diamond Valley Lake/Lake Skinner (Proposed Constrained Linkages 17 and 18), the proposed linkages and core areas from Diamond Valley Lake/Lake Skinner to the San Jacinto Mountains and Wilson Valley (Proposed Linkage 13 and 14 and Proposed Cores 4 and 7) and the linkages from the Santa Rosa Plateau to Orange County (Proposed Linkage 9) and San Diego County (Proposed Constrained Linkages 9, 10, 11, and 12). Also reduced conservation would occur in the Badlands, Reche Canyon, Wilson Valley, Vail Lake, and Temecula Creek areas under this alternative.

Absence of these cores and linkages would have significant effects with respect to certain species, as well as overall function of the MSHCP Conservation Area. For example, the absence of the linkages from French Valley to the Diamond Valley Lake/Lake Skinner Reserve would affect movement by common mammals and avian species in this area and isolate populations of species occurring within the Diamond Valley Lake/Lake Skinner Reserve. The exclusion of Cactus Valley (Proposed Core 4) from the MSHCP Conservation Area would adversely affect the function of the MSHCP Conservation Area by not providing a connection from Diamond Valley Lake/Lake Skinner to National Forest Lands to the east. Absence of this linkage would isolate the existing multi-species reserve from existing conserved lands to the east. Take authorized in this area would adversely affect planning species identified for this Proposed Core, including Quino checkerspot butterfly. These effects are regarded as significant.

Assembly of the cores and linkages will occur in accordance with the reserve assembly process outlined in the MSHCP Plan, Volume I. However, the combination of constrained linkages and a less robust reserve design under this alternative may affect the ability of the cores and linkages to function. This is regarded as a significant effect.

Relationship to Adopted or Approved HCPs and NCCPs. The following discussion focuses on regional planning efforts. Significant impacts are anticipated due to the failure to maintain critical linkage components present in other adopted HCPs and NCCPs.

San Bernardino Preliminary MSHCP Planning Area. Connections to the San Bernardino Preliminary MSHCP Area to the north are generally the same as discussed for Proposed MSHCP with the exception that Proposed Noncontinuous Habitat Block 2 has been reduced in size, and Proposed Linkage 4 has been eliminated. Proposed Linkage 4 served to create missing linkage 36 in the California Wilderness Coalition Report. Elimination of this connection north into the San Bernardino Mountains could cause conflicts with regional conservation planning efforts, although the San Bernardino MSHCP is not yet adopted or approved.

Coachella Valley MSHCP Alternative 2. Impacts to connections to the Coachella Valley MSHCP area to the east are essentially the same as discussed for the Proposed MSHCP.

San Diego MSCP North County Subarea and MHCOSP. Impacts to connection to resource planning areas in San Diego County to the south are generally the same as discussed for the Proposed MSHCP; however, Proposed Linkage 9 is eliminated under this alternative. Proposed Linkage 9 serves as one of the missing linkages identified as a high priority linkage in the California Wilderness Coalition Report (linkage 55) providing connection to the southeast corner of Cleveland National Forest. Elimination of this linkage could cause conflicts with regional habitat conservation plans and is considered to be a significant impact.

Orange County Proposed Southern, and Central and Coastal Subregion NCCP Planning Area. Connections to the Orange County NCCP Planning Areas to the west are the same as discussed for the Proposed Project. Regional conservation planning impacts discussed under the Proposed MSHCP also apply to this alternative.

Missing Linkages in the California Wilderness Coalition Report. This alternative eliminates Proposed Extension of Existing Core 2. This core extension serves as missing linkage 45 identified in the California Wilderness Coalition Report connecting the Santa Ana Mountains to Lake Matthews. This alternative also eliminates Proposed Constrained Linkages 15 and 18. Proposed Constrained Linkages 15 and 18 serve as missing linkage 58 connecting Diamond Valley Lake to west of Temecula. Elimination of these missing linkages could cause conflicts to regional conservation planning and is considered to be a significant impact. In addition, elimination of the missing linkages discussed under connections north and south into San Bernardino and San Diego Counties, respectively, are also considered to be significant impacts under this alternative.

The same features incorporated in the MSHCP to minimize edge effects would be incorporated in this alternative, including the standard BMPs; Land Use Guidelines Pertaining to the Urban/Wildlands Interface; and siting, design, construction, operations, and maintenance guidelines for Covered Activities and Allowable Uses. However, significant edge effects would remain even with implementation of these minimization measures because of the reduction in cores and linkages under this alternative when compared with the proposed MSHCP.

Listed and Proposed Species Alternative

Vegetation Communities. For sensitive upland communities within the MSHCP Area, implementation of this alternative would authorize take of 46 percent of the chaparral, 59 percent of the coastal sage scrub, 91 percent of the desert scrub, 78 percent of the grassland (including native and non-native grassland), and 44 percent of the Riversidean alluvial fan sage scrub (Table 4I). For wetland communities within the MSHCP Area, this alternative would authorize take of 82 percent of the meadows and marshes, 11 percent of the playas and vernal pools, 18 percent of water, and 40 percent of the riparian scrub, woodland and forest. For forest communities within the MSHCP Area, this alternative would authorize take of 31 percent of the montane coniferous forest, and 35 percent of woodlands and forests. In addition, 84 percent of the agricultural land in the Plan Area would be within the area subject to take authorization by implementation of this alternative.

Certain features incorporated in the MSHCP would minimize impacts to sensitive vegetation communities. These include assembly of an approximately 440,800-acre MSHCP Conservation Area encompassing Conserved Habitat. Conserved Habitat is defined as land that is permanently protected and managed for the benefit of the Covered Species under this alternative under legal arrangements that prevent its conversion to other uses. Under this alternative, to the extent the vegetation communities are not authorized for take, they would be included as Conserved Habitat within the MSHCP Conservation Area. For example, 31 percent of the montane coniferous forest would be in the take authorized area under this alternative, and 69 percent of the montane coniferous forest would be included in the MSHCP Conservation Area as Conserved Habitat. In general, inclusion of the majority of the forest communities as Conserved Habitat within the MSHCP Conservation Area under this alternative would reduce identified impacts to these communities to a level below significance.

For the sensitive upland communities, inclusion of 54 percent of the chaparral within the MSHCP Conservation Area under this alternative would reduce identified impacts to these communities to a level below significance given the large percentage of this vegetation community to be included as Conserved Habitat, the extensive acreage and wide distribution of this vegetation community in the Plan Area, and the relatively low numbers of listed species preferring this vegetation community within the Plan Area. For Riversidean alluvial fan sage scrub, although 56 percent of this vegetation community would be included as Conserved Habitat under this alternative, significant impacts to Riversidean alluvial fan sage scrub would remain due to the patchy distribution of this vegetation community in the Plan Area and the relatively large numbers of sensitive species occurring in this vegetation community. Due to the large percentages of coastal sage scrub (59%), grassland (78%) (including native and nonnative grassland), and desert scrub (91%) potentially within the area subject to take authorization within the take authorized area, significant impacts to these vegetation communities would occur even with application of the minimization measures. With respect to agriculture, although the proposed take authorization under this alternative would apply to 84 percent of this vegetation community, this vegetation community is not a sensitive natural community, so impacts to agriculture are not considered biologically significant. (As noted previously, impacts to agriculture are analyzed in Section 4.2, and impacts to species that utilize agricultural lands have been analyzed in the discussions of impacts to Listed Covered Species and impacts to Non-Listed Covered Species.)

Notes: 1 Impacts associated with the No Project Alternative are presented separately. 2 Includes cismontane alkali marsh. 3 Totals exclude developed/disturbed land, because no additional impact to biological resources would occur in these areas as a result of implementation of the Proposed MSHCP or alternatives. Source: MSHCP.

Section 6.1.2 of the MSHCP contains policies related to riparian, riverine, and vernal pool areas that call for mapping of riparian, riverine, vernal pools, and other potentially jurisdictional wetland areas as part of review of applications for Covered Activities within the MSHCP Area. The policy calls for avoidance and minimization of impacts to these areas throughout the Plan Area in accordance with existing regulatory standards. Together, inclusion of substantial acreages of wetland vegetation communities within the MSHCP Conservation Area under this alternative, and implementation of the riparian, riverine, and vernal pool policy incorporated in the MSHCP, would reduce identified impacts to wetland vegetation communities to a level below significance.

Listed Covered Species. The Listed and Proposed Species Alternative encompasses approximately 440,800 acres, comprising 440,800 acres of public/quasi-public land and 93,800 acres of Additional Reserve Lands, and conserves portions of all vegetation communities distributed throughout the MSHCP Area. Representative vegetation communities from the seven bioregions in the Plan Area are conserved under this scenario. No developed or disturbed habitats are proposed for conservation.

As a result of issuance of a 10(a) permit, the species identified in Table 4B could be legally taken by permitted jurisdictions where they occur outside of the MSHCP Conservation Area. The list of Listed Covered Species for this alternative is the same as for the proposed MSHCP. Likewise, the Covered Activities permitted under this alternative would be identical to those described for the MSHCP. Therefore, the impacts associated with Covered Activities would be the same as for the MSHCP.

The Listed Covered Species would be directly impacted by the alternative because they will no longer receive protection outside of the MSHCP Conservation Area. The impacts to the 32 Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Listed Covered Species (Table 4B). The impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP. For example, loss of suitable habitat for southwestern willow flycatcher would be 4,990 acres (36%) under this alternative, while the loss of suitable habitat under the proposed MSHCP would be approximately 3,220 acres (23%). For certain Listed Covered Species, such as Munz's onion, the precise quantity of the impact is undetermined at this time due to lack of existing available information regarding these species.

Features are incorporated into the Listed and Proposed Species Alternative to minimize impacts to Listed Covered Species. These include assembly of a Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of coastal California gnatcatcher at Alberhill, North Peak, Kabian Park, and Ramsgate would be conserved, as well as linkages, such as the Sedco Hills and Gavilan Plateau, to other localities in the MSHCP Area. Criteria-based Reserve Assembly would occur in a manner consistent with Reserve Assembly process described in Section 6.1.1, MSHCP, Volume I.

In addition, this alternative includes policies that would afford some additional protection to Listed Covered Species occurring outside of the MSHCP Conservation Area. The narrow endemics plant species policy and the additional survey needs policy, described in Sections 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Munz's onion
San Diego ambrosia
San Jacinto Valley crownscale
Nevin's barberry

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information-gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that provides for long-term conservation of these species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of the this policy, survey, mapping, and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For mapped habitat located outside of the MSHCP Conservation Area, avoidance and minimization measures, consistent with existing regulations, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting a number of Listed Covered Species. The following Listed Covered Species would benefit from implementation of the policy related to riparian, riverine, and vernal pool areas.

Listed Covered Wetland Species

vernal pool fairy shrimp
Riverside fairy shrimp
Santa Ana sucker
arroyo toad
California red-legged frog
mountain yellow-legged frog
western yellow-billed cuckoo
bald eagle

least Bell's vireo
California Orcutt grass
San Jacinto Valley crownscale
thread-leaved brodiaea
San Diego button-celery
spreading navarretia
southwestern willow flycatcher
peregrine falcon

If suitable habitat were determined to be present, focused surveys for the following Listed Covered Species would be conducted: least Bell's vireo, southwestern willow flycatcher, western yellow-billed cuckoo, vernal pool fairy shrimp and Riverside fairy shrimp. Localities of wetland species observed during focused surveys would be conserved in accordance with policies contained in Section 6.1.2 of the MSHCP.

A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, and Anza Valley is anticipated under this alternative when compared to the proposed MSHCP. Areas such as the Jurupa Mountain, Cactus Valley, Badlands, Reche Canyon, Lakeview Mountains, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area, would be excluded under this alternative. Nevertheless, with application of the narrow endemic policy, additional survey needs policy, and riparian, riverine, and vernal pool policy, as well as Reserve Assembly and configuration, impacts to Listed Covered Species would be less than significant.

Non-Listed Covered Species. Implementation of the Listed and Proposed Species Alternative would result in direct and indirect impacts to Non-Listed Covered Species outside the MSHCP Conservation Area. The list of Non-Listed Covered Species for this alternative is included in Table 4J. The analysis summary for these species is contained in Table 4C.

The impacts to the Non-Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Non-Listed Covered Species (Table 4C). The impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP. For example, loss of suitable habitat for yellow-breasted chat would be 4,310 acres (35%) under this alternative, and the loss of suitable habitat under the proposed MSHCP would be approximately 2,780 acres (22%) (Table 4C). For certain Non-Listed Covered Species, such as arroyo chub and San Bernardino flying squirrel, the precise quantity of the impact is undetermined at this time due to lack of existing available information regarding these species.

Features are incorporated into the Listed and Proposed Species Alternative to minimize impacts to Non-Listed Covered Species. These include assembly of a Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of Bell's sage sparrow at Lake Skinner/Diamond Valley Lake, Aguanga, and the Jurupa Mountains, would be conserved, as well as linkages, such as the Sedco Hills and Hogbacks, to other localities in the MSHCP Area. Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Process described in Section 6.1.1, MSHCP, Volume I.

In addition, this alternative includes policies that would afford some additional protection to Listed Covered Species occurring outside of the MSHCP Conservation Area . The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Non-Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Narrow Endemic Plant Species Policy

Johnston's rock-cress
Munz's mariposa lily
many-stemmed dudleya

San Jacinto Mountains bedstraw
San Miguel savory
Wright's trichocoronis

Additional Survey Needs Policy

smooth tarplant
Coulter's goldfields

Parish's brittlescale
Nevin's barberry

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information-gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that provides for long-term conservation of these species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of that policy, survey, mapping and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For mapped habitat located outside of the MSHCP Conservation Area, avoidance and minimization measures, consistent with existing regulations, would be employed. The avoidance and minimization measures would reduce impacts to areas supporting a number of Non-Listed Covered Species. The following Non-Listed Covered Species would benefit from implementation of the riparian, riverine, and vernal pool policy.

A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, and Anza Valley is anticipated under this alternative when compared to the proposed MSHCP. Areas such as the Jurupa Mountain, Cactus Valley, Badlands, Reche Canyon, Lakeview Mountains, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area would be excluded under this alternative. Nevertheless, with application of the narrow endemic policy, additional survey needs policy and riparian, riverine, and wetlands policy, as well as Reserve Assembly and configuration, impacts to Non-Listed Covered Species would be reduced to less than significant levels.

Non-Covered Species. The list of defined Non-Covered Species for the Listed and Proposed Species Alternative is included in Table 4K. Any conservation benefits that would accrue to these species as a result of the MSHCP developed under the Listed and Proposed Species alternative would likely be reduced, due to the reduction in overall Conservation Area. However, as noted, it is not possible to fully quantify the potential adverse effects to Non-Covered Species at this time due to the lack of information for these species. Therefore, impacts to Non-Covered Species, including impacts resulting from Covered Activities, under this alternative are deemed to be significant and unavoidable. Please also refer to discussion of impacts to non-covered species for the proposed MSHCP.

Cores and Linkages. Under the Listed and Proposed Species Alternative, all of the cores and linkages noted in Table 4E and depicted in Figure 4.1.3 would be incorporated into the MSHCP Conservation Area. As noted in the discussion of the Relationship to adopted or approved HCPs and NCCPs, these cores and linkages include some of the missing links identified by the California Wilderness Coalition in their study of linkage priorities in the South Coast Ecoregion, for which the MSHCP has the ability to incorporate such cores and linkages. Table 4E identifies the proposed cores and linkages that are not included as part of this alternative. In addition to the proposed cores and linkages identified as not a part of the Conservation Area under the Listed, Proposed, and Strong Candidate Species Alternative, this alternative also omits proposed core and linkage areas in the Lakeview Mountains, Badlands, Reche Canyon, Tule Creek, and Temecula Creek east of Vail Lake. Also, reduced conservation would occur at Wilson Valley, Vail Lake, and Anza Valley areas under this alternative.

Absence of these cores and linkages would have significant effects with respect to certain species, as well as overall function of the MSHCP Conservation Area. In addition to the significant effects associated with implementation of the Listed, Proposed, and Strong Candidate Species Alternative, significant effects resulting from the exclusion of the Badlands, Reche Canyon, Lakeview Mountains, Tule Creek, and Temecula Creek would occur. For example, under this alternative, the reserve design in the Badlands would be less robust due to the reduced number of acres conserved when compared to the proposed MSHCP. This alternative would not provide large habitat blocks in the Badlands for foraging raptors or mammals connecting to the National Forest lands. The absence of Temecula and Tule Creeks as linkages further isolates core areas in Anza Valley and the Agua Tibia Wilderness.

Assembly of the cores and linkages will occur in accordance with the MSHCP Criteria and the Habitat Evaluation and Acquisition Negotiation Process. However, as noted in Section 3 of the MSHCP, Volume I and in Table 4E of this document, a number of the identified linkages are regarded as constrained linkages and would be within the area subject to take authorization. The combination of constrained linkages and a less robust reserve design under this alternative may affect the ability of the cores and linkages to function. This is regarded as a significant effect.

San Bernardino Preliminary MSHCP Planning Area. Connections to the San Bernardino Preliminary MSHCP Planning Area to the north are generally the same as discussed for the Listed, Proposed, and Strong Candidate Alternative with the exception that Proposed Linkages 5 and 6 have been reduced in size. Impacts discussed for the Listed, Proposed, and Strong Candidate Species Alternative also apply to the Listed and Proposed Species Alternative.

Coachella Valley MSHCP Alternative 2. Connections to the Coachella Valley MSHCP Area to the east are essentially the same as discussed for the Listed, Proposed, and Strong Candidate Alternative.

San Diego MSCP North County Subarea and MHCOSP. Connections to resource planning areas in San Diego County to the south are the same as discussed for the Listed, Proposed and Strong Candidate Species Alternative. Significant impacts discussed under the Listed, Proposed, and Strong Candidate Species Alternative also apply to this alternative.

Orange County Proposed Southern, and Central and Coastal Subregion NCCP Planning Area. Connections to the Orange County NCCP Planning Areas to the west are the same as discussed for the Proposed Project. Regional resource planning impacts discussed under the Listed, Proposed, and Strong Candidate Species Alternative also apply to this alternative.

Missing Linkages in the California Wilderness Coalition Report. Regional planning impacts are the same as those discussed under the Listed, Proposed, and Strong Candidate Species Alternative.

Edge Effects. The types of edge effects under this alternative would be the same as for the proposed MSHCP, and identified impacts would be minimized by the same features incorporated in the MSHCP. As noted in the discussion of Impacts to cores and linkages under this alternative (and identified in Table 4E), all of the proposed cores and linkages and extensions of existing cores and linkages would be absent from this alternative. For these absent cores and linkages under this alternative, no edge effects would occur. Given the greatly increased take authorized area, and the fact that existing cores would remain isolated and would not be connected by new proposed cores and linkages, it is anticipated that significant edge effects would occur for all of the existing cores and linkages under this alternative with the exception of the existing Cleveland and San Bernardino National Forest cores. Edge effects to Conserved Habitats and Covered Species within these cores and linkages would be greater than would occur under the proposed MSHCP. Under this alternative, edge effects to sensitive species not included on the Covered Species list for this alternative, but present within the Conserved Habitat areas, would also occur. The same features incorporated in the MSHCP under the proposed MSHCP to minimize edge effects would be incorporated in this alternative, including the standard BMPs; the Land Use Guidelines Pertaining to Urban/Wildlands Interface; and siting, design, construction, operations, and maintenance guidelines for Covered Activities and Allowable Uses. Significant edge effects would remain even with implementation of these minimization measures for all of the existing cores and

Existing Reserves Alternative

Vegetation Communities. For sensitive upland communities within the MSHCP Plan Area, implementation of this alternative would provide take authorization within areas that include 52 percent of the chaparral, 78 percent of the coastal sage scrub, 91 percent of the desert scrub, 85 percent of the grassland (including native and non-native grassland), and 74 percent of the Riversidean alluvial fan sage scrub (Table 4L). For wetland communities within the MSHCP Plan Area, this alternative would provide take authorization within areas that include 86 percent of the meadows and marshes, 63 percent of the playas and vernal pools, 25 percent of water, and 52 percent of the riparian scrub, woodland and forest. For forest communities within the MSHCP Plan Area, this alternative would provide take authorization in areas that include 31 percent of the montane coniferous forest and 38 percent of the woodlands and forests. In addition, 93 percent of the agricultural land in the Plan Area would be within areas subject to take authorization in this alternative.
