This book was released on 2001 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The status of wild sheep in North America typifies the plight of many wildlife species in modern times: wild sheep have declined to 10-40% of their numbers during pristine times and on a global scale approximately 31% of Caprine are considered threatened or critical. As human populations and the number of threatened and endangered wildlife species increase, research into the causes of wildlife population declines and tools to aid recovery are urgently needed. We conducted two studies of endangered desert bighorn sheep (Ovis canadensis nelsoni) in the Peninsular Ranges of Southern California with the primary goal of furthering recovery efforts for this species. First, in order to evaluate a captive breeding program for Peninsular bighorn, we developed the following criteria to provide a standard means of evaluating ongoing captive breeding and reintroduction programs: (1) survival and recruitment rates in the captive population, (2) survival of released animals, (3) recruitment of released animals, (4) growth rate of the reintroduced or augmented population, and (5) establishment of a viable wild population. In assessing the Peninsular bighorn sheep program, we found that while reintroduction did not result in population growth or establishment of a viable population, it helped prevent extirpation of the reinforced deme, preserved metapopulation linkage, and aided habitat preservation. Chronic low recruitment and low adult survivorship precluded achievement of criteria 3-5. Environmental conditions in the release area also appeared to hinder program success. We suggest that periodic evaluations are useful for improving the success of individual captive breeding and reintroduction programs, as well as for meta-analyses needed to refine reintroduction science as a recovery tool for threatened or endangered populations. Wildlife habituated to the presence of humans have been recognized as a new dilemma facing wildlife managers. Our second study involved examining the habitat use, home range size, and nutritional levels of Peninsular desert bighorn sheep along an urbanwildland interface during two time periods (1981-82 and 1995-98). We found that bighorn sheep monitored during 1995-98 used habitat within (P

Available in PDF, EPUB and Kindle. Book excerpt: I examined biodiversity management issues, implications and opportunities in a working industrial landscape of the San Bernardino Mountains, California, USA, where historic and active mining operations overlap habitat occupied by threatened, endangered or protected plant and animal tax. To elucidate patterns of habitat use by ungulates in a mini-influenced landscape, I evaluated resource selection by the Cushenbury population of desert bighorn sheep (Ovis Canadensis nelsoni). Modeling of a resource selection function (RSF) for that population identified proximity to active mine areas, water sources, and revegetation sites as important determinants of habitat selection. Next, I reviewed two collaborative dialogues between the public, private and civil sectors resulting in workable solutions achieving biodiversity conservation goals simultaneous with economic development: a habitat management strategy for threatened and endangered plants and a research collaborative focused on the long-term viability of an isolated bighorn sheep population. Finally, I integrated results of RSF modeling with principles adopted by those two initiatives into a conceptual framework to aid the development of an adaptive management plan for the Cushenbury bighorn sheep population. A formulation of conservation value is presented using results of RSF analysis and mitigation credits reflecting the degree to which degraded habitat is enhanced to benefit wild sheep. The proposed Bighorn Habitat Assessment Tool (BHAT) seeks to a) establish a habitat reserve providing maximum benefit to the unique requirements of bighorn sheep, b) incentivize voluntary actions by industry to ensure mining activities are compatible with bighorn sheep conservation, and c) allow for the objective evaluation of multiple mine planning and resource management alternatives.
