ANDREW California Department of Fish and Game 78-078 Country Club Drive, Suite 109 Bermuda Dunes, CA 92201 Desert mule deer, Odocoileus hemionus eremicus, occur at low densities in the Sonoran Desert of southeastern California and consequently are difficult to monitor using standard wildlife techniques. We used radiocollared deer, remote photography at wildlife water developments (i.e., catchments), and mark-recapture techniques to estimate population abundance and sex and age ratios. Abundance estimates for 1999-2004 ranged from 40 to 106 deer, resulting in density estimates of 0.05-0.13 deer/km2. Ranges in herd composition were 41-74% (females), 6-31% (males), and 6-34% (young). There was a positive correlation (R = 0.73, P = 0.051) between abundance estimates and number of deer photographed/ catchment-day, and that relationship may be useful as an index of abundance in the absence of marked deer for mark-recapture methods. Because of the variable nature of desert wildlife populations, implementing 55 56 CALIFORNIA FISH AND GAME strategies that recognize that variability and conserving the habitat that allow populations to fluctuate naturally will be necessary for long-term conservation. -

DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP MF-1603-A UNITED STATES GEOLOGICAL SURVEY MINERAL RESOURCE POTENTIAL OF THE COXCOMB MOUNTAINS WILDERNESS STUDY AREA (CDCA-328), SAN BERNARDINO AND RIVERSIDE COUNTIES, CALIFORNIA SUMMARY REPORT By J. P. Calzia, J. E. Kilburn, R. W. Simpson, Jr., and C. M. Alien U.S. Geological Survey and A. M. Leszcykowski and J. D. Causey U.S. Bureau of Mines STUDIES RELATED TO WILDERNESS Bureau of Land Management Wilderness Study Areas The Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976) requires the U.S. Geological Survey and the U.S. Bureau of Mines to conduct mineral surveys on certain areas to determine their mineral resource potential. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results of a mineral survey of the Coxcomb Mountains Wilderness Study Area (CDCA-328), California Desert Conservation Area, Riverside and San Bernardino Counties, California. SUMMARY Geologic, geochemical, geophysical, and mineral surveys within the Coxcomb Mountains Wilderness Study Area in south eastern California define several areas with low to moderate potential for base and precious metals. Inferred subeconomic re sources of gold at the Moser mine (area Ha) are estimated at 150,000 tons averaging 1.7 ppm Au. The remainder of the study area has low potential for other mineral and energy resources including radioactive minerals and geothermal resources. Oil, gas, and coal resources are not present within the wilderness study area. INTRODUCTION Hope (1966), Greene (1968), and Calzia (1982) indicate that the wilderness study area is underlain by metaigneous and The Coxcomb Mountains Wilderness Study Area metasedimentary rocks of Jurassic and (or) older age intruded (CDCA-328) is located in the Mojave Desert of southeastern by granitic rocks of Late Jurassic to Late Cretaceous age. -
The Imperial Valley Is Located About 150 Miles Southeast of Los Angeles
The Imperial Valley is located about 150 miles southeast of Los Angeles. It is a section of a much larger geologic structure -- the Salton Trough -- which is about 1,000 miles in length. The structure extends from San Gorgonio Pass southeast to the Mexican border, including the Gulf of California and beyond the tip of the Baja California Peninsula. The surrounding mountains are largely faulted blocks of the Southern California batholith of Mesozoic age, overlain by fragments of an earlier metamorphic complex. The valley basin consists of a sedimentary fill of sands and gravels ranging up to 15,000 feet in thickness. The layers slope gently down-valley, and contain several important aquifers. The valley is laced with major members of the San Andreas Fault system. Minor to moderate earthquake events are common, but severe shocks have not been experienced in recorded history. The entire trough, including the Gulf is an extension of the East Pacific Rise, a zone of separation in Earth's crust. Deep sea submergence instruments have observed many phenomena of crustal formation. The axis of the Rise, hence of the Salton Valley as well, is a great transform fault that is having the effect of separating an enormous slab of North America, consisting of the Baja Peninsula and coastal California away from the mainland, with movement to the northwest and out to sea as a terranne.

Terrestrial Mammal Species of Special Concern in California, Bolster, B.C., Ed., 1998 27
Terrestrial Mammal Species of Special Concern in California, Bolster, B.C., Ed., 1998 27 California leaf-nosed bat, Macrotus californicus Elizabeth D. Pierson & William E. Rainey Description: Macrotus californicus is one of two phyllostomid species that occur in California. It is a medium sized bat (forearm = 46-52 mm, weight = 12-22 g), with grey pelage and long (>25 mm) ears. It can be distinguished from all other long-eared bats by the presence of a distinct nose leaf, which is erect and lanceolate (Hoffmeister 1986). The only other California species with a leaf-shaped nose projection, Choeronycteris mexicana, has very short ears. Corynorhinus townsendii, the other long-eared species with which M. californicus could most readily be confused, can be distinguished by the presence of bilateral nose lumps as opposed to a single nose leaf. Antrozous pallidus has long ears and a scroll pattern around the nostrils instead of a nose leaf. M. californicus has a tail which extends beyond the edge of the tail membrane by 5-10 mm. Taxonomic Remarks: M. californicus, a member of the Family Phyllostomidae, has sometimes been considered a subspecies of Macrotus waterhousii (Anderson and Nelson 1965), but more recently, based primarily on chromosomal characters, has been treated as a separate species (Davis and Baker 1974, Greenbaum and Baker 1976, Baker 1979, Straney et al. 1979). The form now recognized as M. californicus was first described from a specimen collected at Old Fort Yuma, Imperial County (Baird 1859). There are currently two species recognized in the genus Macrotus (Koopman 1993). Only M. californicus occurs in the United States. -

The California Desert CONSERVATION AREA PLAN 1980 As Amended
the California Desert CONSERVATION AREA PLAN 1980 as amended U.S. DEPARTMENT OF THE INTERIOR BUREAU OF LAND MANAGEMENT U.S. Department of the Interior Bureau of Land Management Desert District Riverside, California the California Desert CONSERVATION AREA PLAN 1980 as Amended IN REPLY REFER TO United States Department of the Interior BUREAU OF LAND MANAGEMENT STATE OFFICE Federal Office Building 2800 Cottage Way Sacramento, California 95825 Dear Reader: Thank you.You and many other interested citizens like you have made this California Desert Conservation Area Plan. It was conceived of your interests and concerns, born into law through your elected representatives, molded by your direct personal involvement, matured and refined through public conflict, interaction, and compromise, and completed as a result of your review, comment and advice. It is a good plan. You have reason to be proud. Perhaps, as individuals, we may say, “This is not exactly the plan I would like,” but together we can say, “This is a plan we can agree on, it is fair, and it is possible.” This is the most important part of all, because this Plan is only a beginning. A plan is a piece of paper-what counts is what happens on the ground. The California Desert Plan encompasses a tremendous area and many different resources and uses. The decisions in the Plan are major and important, but they are only general guides to site—specific actions. The job ahead of us now involves three tasks: —Site-specific plans, such as grazing allotment management plans or vehicle route designation; —On-the-ground actions, such as granting mineral leases, developing water sources for wildlife, building fences for livestock pastures or for protecting petroglyphs; and —Keeping people informed of and involved in putting the Plan to work on the ground, and in changing the Plan to meet future needs. -
