    "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."

    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

    3.4 Biological Resources for the Purpose of This EIR, Biological Resources Comprise Vegetation, Wildlife, Natural Communities, and Wetlands and Other Waters

    Impact Analysis Alameda County Community Development Agency Biological Resources 3.4 Biological Resources For the purpose of this EIR, biological resources comprise vegetation, wildlife, natural communities, and wetlands and other waters. Potential biological resource impacts associated with the program and the two individual projects are analyzed. Potential impacts are described quantitatively and qualitatively in Section 3.4.2, Environmental Impacts. This section also identifies specific and detailed measures to avoid, minimize, or compensate for potentially significant impacts on biological resources, where necessary. 3.4.1 Existing Conditions Regulatory Setting Federal Endangered Species Act Pursuant to the federal Endangered Species Act (ESA), USFWS and the National Marine Fisheries Service (NMFS) have authority over projects that may result in take of a species listed as threatened or endangered under the act. Take is defined under the ESA, in part, as killing, harming, or harassing. Under federal regulations, take is further defined to include habitat modification or degradation that results, or is reasonably expected to result, in death or injury to wildlife by significantly impairing essential behavioral patterns, including breeding, feeding, or sheltering. If a likelihood exists that a project would result in take of a federally listed species, either an incidental take permit, under Section 10(a) of the ESA, or a federal interagency consultation, under Section 7 of the ESA, is required. Several federally listed species—vernal pool fairy shrimp (Branchinecta lynchi), longhorn fairy shrimp (Branchinecta longiantenna), vernal pool tadpole shrimp (Lepidurus packardi), California tiger salamander (Ambystoma californiense), California red‐legged frog (Rana draytonii), Alameda whipsnake (Masticophis lateralis euryxanthus), and San Joaquin kit fox (Vulpes macrotis mutica)—have the potential to be affected by activities associated with the Golden Hills and Patterson Pass projects as well as subsequent repowering projects.

    4.9 Biological Resources

    METROPOLITAN BAKERSFIELD METROPOLITAN BAKERSFIELD GENERAL PLAN UPDATE EIR 4.9 BIOLOGICAL RESOURCES The purpose of this Section is to identify existing biological resources within the Metropolitan Bakersfield area. In addition, this Section provides an assessment of biological resources (including sensitive species) impacts that may result from implementation of the General Plan Update references General Plan goals and policies, and, where necessary, recommends mitigation measures to reduce the significance of impacts. This Section describes the biological character of the site in terms of vegetation, flora, wildlife, and wildlife habitats and analyzes the biological significance of the site in view of Federal, State and local laws and policies. ENVIRONMENTAL SETTING The study area for the Metropolitan Bakersfield General Plan Update encompasses 408 square miles of the southern portion of the San Joaquin Valley, the southernmost basin of the Central Valley of California. Prior to industrial, agricultural and urban development, the San Joaquin Valley comprised a variety of ecological communities. Runoff from the surrounding mountains fostered hardwood and riparian forests, marshes and grassland communities. Away from the influence of the mountain runoff, several distinct dryland communities of grasses and shrubs developed along gradients of rainfall, soil texture and soil alkalinity, providing a mosaic of habitats for the assemblage of endemic plants and animals. Agriculture, urban development and oil/gas extraction have resulted in many changes in the natural environment of the San Joaquin Valley. For example, lakes and wetlands in the delta area have been drained and diverted, native plant and animal species have been lost and a decrease in the acreage of native lands has occurred.

The leaves are wavy-margined and most are in a basal rosette.

Results will be incorporated into a multi-species recovery plan as well as restoration and management plans for the CPNA and other preserves. In terms of plant size and reproduction, the most successful populations of Caulanthus caqomicus were those on the CPNA, whereas Lembertia congdonii was equally successful on the CPNA and in the Kettleman Hills. Of the four Eriastrum hooveri sites studied, plants on the CPNA were smallest with poorest reproduction. Grazing effects were compared in three populations of L. congdonii, each of which was divided into grazed and ungrazed portions. Reproduction of L. congdonii was greater in grazed than in ungrazed areas of the Carrizo Plain and Kettleman Hills, whereas the reverse was found on the Elkhorn Plain.
