This book was released on 2011 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes current knowledge on the status and ecology of the Mexican spotted owl within the Upper Gila Mountains Recovery Unit (UGM RU). It was written at the request of U.S. Forest Service personnel involved in the Four Forests Restoration Initiative (4FRI), a collaborative, landscape-scale restoration effort covering approximately 2.4 million ac (1 million ha) across all or part of four National Forests (Apache-Sitgreaves, Coconino, Kaibab, and Tonto National Forests) located within the UGM RU. The UGM RU supports>50% of the known population of Mexican spotted owls, and the central location of the UGM RU within the overall range of the owl appears to facilitate gene flow throughout that range. Consequently, the UGM population is viewed as important to stability within the overall range of the owl, and management that impacts owls within the UGM RU could affect owl populations beyond that RU.

Book excerpt: Despite the potential synergy that can result from basing management applications on results from research, there is a polarization of cultures between wildlife managers and wildlife researchers. Wildlife Science: Connecting Research with Management provides strategies for bridging cultural and communication gaps between these groups. Contributors present case studies highlighting the role of state and federal agencies and private organizations in management and research; the lingering disconnects between grassland birds, quail, and deer research and management; as well as the development of management techniques from field research, rangelands management, and ranch management.

Available in PDF, EPUB and Kindle. Book excerpt: Information regarding population status and abundance of rare species plays a key role in resource management decisions. Ideally, data should be collected using statistically sound sampling methods, but by their very nature, rare or elusive species pose a difficult sampling challenge. Sampling Rare or Elusive Species describes the latest sampling designs and survey methods for reliably estimating occupancy, abundance, and other population parameters of rare, elusive, or otherwise hard-to-detect plants and animals. It offers a mixture of theory and application, with actual examples from terrestrial, aquatic, and marine habitats around the world. Sampling Rare or Elusive Species is the first volume devoted entirely to this topic and provides natural resource professionals with a suite of innovative approaches to gathering population status and trend data. It represents an invaluable reference for natural resource professionals around the world, including fish and wildlife biologists, ecologists, biometricians, natural resource managers, and all others whose work or research involves rare or elusive species.

This book was released on 2000 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the result of a cooperative effort by the Rocky Mountain Research Station and the USDA Forest Service Region 3, with participation by the Arizona Game and Fish Department and the Bureau of Land Management. It assesses the state of knowledge related to the conservation status of the cactus ferruginous pygmy-owl in Arizona. The population decline of this owl has been attributed to the loss of riparian areas before and after the turn of the 20th century. Currently, the cactus ferruginous pygmy-owl is chiefly found in southern Arizona in xeroriparian vegetation and wellstructured upland desertscrub. The primary threat to the remaining pygmy-owl population appears to be continued habitat loss due to residential development. Important information gaps exist and prevent a full understanding of the current population status of the owl and its conservation needs.
Download or read book Dietary Overlap Between Sympatric Mexican Spotted and Great Horned Owls in Arizona written by Joseph L. Ganey and published by . This book was released on 2005 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: We estimated diet composition of sympatric Mexican spotted (Strix occidentalis lucida, n = 7 pairs of owls) and great horned owls (Bubo virginianus, n = 4 pairs) in ponderosa pine (Pinus ponderosa) - Gambel oak (Quercus gambelii) forest, northern Arizona. Both species preyed on mammals, birds, and insects; great horned owls also ate lizards. Mammals dominated the diet of both species. Mammals comprised 63 and 62% of all prey items identified in diets of spotted and great horned owls, respectively, and 94 and 95% of prey biomass. Both species primarily preyed on a few groups of small mammals. Observed overlap in diet composition between species (0.95) was greater than expected based on null models of diet overlap, and the size range of prey taken overlapped entirely. Mean prey mass was similar for both species (great horned owl, 47.0 ± 7.4 g [SE], n = 94 items; spotted owl, 40.1 ± 1.8 g, n = 1,125 items). Great horned owls consumed larger proportions of diurnally active prey than spotted owls, which primarily consumed nocturnally active mammals. Our results, coupled with a previous analysis showing that these owls foraged in the same general areas (Ganey and others 1997), suggests that they could compete for food resources, which are assumed to be limiting in at least some years. They may minimize the potential for resource competition, however, by concentrating foraging activities in different habitats (Ganey and others 1997) and by foraging at different times, when different suites of prey species are active.

Download or read book Final Recovery Plan for the Mexcian Spotted Owl Strix Occidentalis Lucida written by and published by . This book was released on 2012 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 1993 the U.S. Fish and Wildlife Service (FWS) listed the Mexican spotted owl (Strix occidentalis lucida; "owl") as threatened under the Endangered Species Act (ESA). Critical habitat for the Mexican spotted owl was designated in 2004, comprising approximately 3.5 million hectares (ha) (8.6 million acres [ac]) on Federal lands in Arizona, Colorado, New Mexico, and Utah (69 FR 53182). Within the critical habitat boundaries, critical habitat includes protected and restricted habitats as defined in the original Mexican Spotted Owl Recovery Plan, completed in 1995. The species' recovery priority number is 9C, pursuant to the Endangered and Threatened Species Listing and Recovery Priority Guidelines (48 FR 43098). The Mexican spotted owl meets the species recovery priority 9C category due to its moderate degree of threat, high recovery potential, taxonomic classification as a subspecies, and conflict with construction or other economic activities. Surveys since the 1995 Recovery Plan have increased our knowledge of owl distribution but not necessarily of owl abundance. An owl site is an area with a high probability of being used by a single or a pair of adult or subadult owls for nesting, roosting, or foraging. For the current revision, the Recovery Team compiled over 1,300 owl sites known today in the U.S. portion of the owl's range (Table II.1; Table B.1 in Appendix B). The increase in the number of owl sites is mainly a product of new surveys being completed within previously unsurveyed areas (e.g., several National Parks within southern Utah, Grand Canyon in Arizona, Guadalupe National Park in West Texas, Guadalupe Mountains in southeastern New Mexico and West Texas, Dinosaur National Monument in Colorado, and Cibola National Forest in New Mexico), with only a few additions to numbers of sites recorded for previously well-surveyed National Forests. Thus, an increase in abundance cannot be inferred from these data."
