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."

This book was released on 2005 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of the federally threatened Mexican spotted owl (MSO; Strix occidentalis lucida) has been a major concern, both technical and political, for forest managers in the southwestern United States. So has the need to reduce the risk of stand-replacing wildfire in the regions ponderosa pine forests.Managers have generally shied away from linking these two concerns, fearing that the consultation required under the federal Endangered Species Act makes forest restoration treatments in or adjacent to MSO habitat too cumbersome. Yet carefully planned and implemented restoration treatments either around or in MSO habitat are crucial to the species future survival, and can be accomplished. They can be designed to maximize benefits to forest health while minimizing negative impacts toand in some cases actively benefitingthe MSO and/or its habitat. There will never be 100 percent agreement between reducing fire risk and maintaining or enhancing MSO habitat needs, but the goal of this public...

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.
