  • Mammals of the California Desert
    MAMMALS OF THE CALIFORNIA DESERT William F. Laudenslayer, Jr. Karen Boyer Buckingham Theodore A. Rado INTRODUCTION I ,+! The desert lands of southern California (Figure 1) support a rich variety of wildlife, of which mammals comprise an important element. Of the 19 living orders of mammals known in the world i- *- loday, nine are represented in the California desert15. Ninety-seven mammal species are known to t ':i he in this area. The southwestern United States has a larger number of mammal subspecies than my other continental area of comparable size (Hall 1981). This high degree of subspeciation, which f I;, ; leads to the development of new species, seems to be due to the great variation in topography, , , elevation, temperature, soils, and isolation caused by natural barriers. The order Rodentia may be k., 2:' , considered the most successful of the mammalian taxa in the desert; it is represented by 48 species Lc - occupying a wide variety of habitats. Bats comprise the second largest contingent of species. Of the 97 mammal species, 48 are found throughout the desert; the remaining 49 occur peripherally, with many restricted to the bordering mountain ranges or the Colorado River Valley. Four of the 97 I ?$ are non-native, having been introduced into the California desert. These are the Virginia opossum, ' >% Rocky Mountain mule deer, horse, and burro. Table 1 lists the desert mammals and their range 1 ;>?-axurrence as well as their current status of endangerment as determined by the U.S. fish and $' Wildlife Service (USWS 1989, 1990) and the California Department of Fish and Game (Calif.

  • IP Athos Renewable Energy Project, Plan of Development, Appendix D.2
    APPENDIX D.2 Plant Survey Memorandum Athos Memo Report To: Aspen Environmental Group From: Lehong Chow, Ironwood Consulting, Inc. Date: April 3, 2019 Re: Athos Supplemental Spring 2019 Botanical Surveys This memo report presents the methods and results for supplemental botanical surveys conducted for the Athos Solar Energy Project in March 2019 and supplements the Biological Resources Technical Report (BRTR; Ironwood 2019) which reported on field surveys conducted in 2018. BACKGROUND Botanical surveys were previously conducted in the spring and fall of 2018 for the entirety of the project site for the Athos Solar Energy Project (Athos). However, due to insufficient rain, many plant species did not germinate for proper identification during 2018 spring surveys. Fall surveys in 2018 were conducted only on a reconnaissance-level due to low levels of rain. Regional winter rainfall from the two nearest weather stations showed rainfall averaging at 0.1 inches during botanical surveys conducted in 2018 (Ironwood, 2019). In addition, gen-tie alignments have changed slightly and alternatives, access roads and spur roads have been added. PURPOSE The purpose of this survey was to survey all new additions and re-survey areas of interest including public lands (limited to portions of the gen-tie segments), parcels supporting native vegetation and habitat, and windblown sandy areas where sensitive plant species may occur. The private land parcels in current or former agricultural use were not surveyed (parcel groups A, B, C, E, and part of G). METHODS Survey Areas: The area surveyed for biological resources included the entirety of gen-tie routes (including alternates), spur roads, access roads on public land, parcels supporting native vegetation (parcel groups D and F), and areas covered by windblown sand where sensitive species may occur (portion of parcel group G).

  • Sierra Nevada Framework FEIS Chapter 3
    table of contrents Sierra Nevada Forest Plan Amendment – Part 4.6 4.6. Vascular Plants, Bryophytes, and Fungi4.6. Fungi Introduction Part 3.1 of this chapter describes landscape-scale vegetation patterns. Part 3.2 describes the vegetative structure, function, and composition of old forest ecosystems, while Part 3.3 describes hardwood ecosystems and Part 3.4 describes aquatic, riparian, and meadow ecosystems. This part focuses on botanical diversity in the Sierra Nevada, beginning with an overview of botanical resources and then presenting a more detailed analysis of the rarest elements of the flora, the threatened, endangered, and sensitive (TES) plants. The bryophytes (mosses and liverworts), lichens, and fungi of the Sierra have been little studied in comparison to the vascular flora. In the Pacific Northwest, studies of these groups have received increased attention due to the President’s Northwest Forest Plan. New and valuable scientific data is being revealed, some of which may apply to species in the Sierra Nevada. This section presents an overview of the vascular plant flora, followed by summaries of what is generally known about bryophytes, lichens, and fungi in the Sierra Nevada. Environmental Consequences of the alternatives are only analyzed for the Threatened, Endangered, and Sensitive plants, which include vascular plants, several bryophytes, and one species of lichen. 4.6.1. Vascular plants4.6.1. plants The diversity of topography, geology, and elevation in the Sierra Nevada combine to create a remarkably diverse flora (see Section 3.1 for an overview of landscape patterns and vegetation dynamics in the Sierra Nevada). More than half of the approximately 5,000 native vascular plant species in California occur in the Sierra Nevada, despite the fact that the range contains less than 20 percent of the state’s land base (Shevock 1996).

  • Ventura County Plant Species of Local Concern
    Checklist of Ventura County Rare Plants (Twenty-second Edition) CNPS, Rare Plant Program David L. Magney Checklist of Ventura County Rare Plants1 By David L. Magney California Native Plant Society, Rare Plant Program, Locally Rare Project Updated 4 January 2017 Ventura County is located in southern California, USA, along the east edge of the Pacific Ocean. The coastal portion occurs along the south and southwestern quarter of the County. Ventura County is bounded by Santa Barbara County on the west, Kern County on the north, Los Angeles County on the east, and the Pacific Ocean generally on the south (Figure 1, General Location Map of Ventura County). Ventura County extends north to 34.9014ºN latitude at the northwest corner of the County. The County extends westward at Rincon Creek to 119.47991ºW longitude, and eastward to 118.63233ºW longitude at the west end of the San Fernando Valley just north of Chatsworth Reservoir. The mainland portion of the County reaches southward to 34.04567ºN latitude between Solromar and Sequit Point west of Malibu. When including Anacapa and San Nicolas Islands, the southernmost extent of the County occurs at 33.21ºN latitude and the westernmost extent at 119.58ºW longitude, on the south side and west sides of San Nicolas Island, respectively. Ventura County occupies 480,996 hectares [ha] (1,188,562 acres [ac]) or 4,810 square kilometers [sq. km] (1,857 sq. miles [mi]), which includes Anacapa and San Nicolas Islands. The mainland portion of the county is 474,852 ha (1,173,380 ac), or 4,748 sq.
