Available in PDF, EPUB and Kindle. Book excerpt: The Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus) was once distributed throughout the colder waters of the Colorado River basin above the Grand Canyon. About 8 percent of its historical range is occupied by unhybridized or ecologically significant populations. It has been petitioned for listing under the Endangered Species Act and is accorded special status by several state and federal agencies. Habitat alteration and nonnative trout invasions led to the extirpation of many populations and impede restoration. Habitat fragmentation exacerbated by climate change is an emerging threat. A strategic, systematic approach to future conservation is likely to be the most successful.

This book was released on 2006 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Conservation Strategy (Strategy) has been developed to direct implementation of conservation measures for Colorado River cutthroat trout (CRCT) in Colorado, Utah, and Wyoming as a collaborative and cooperative effort among resource agencies. Threats that warrant CRCT listing as a special status species by state and federal agencies and might lead to listing under the Endangered Species Act of 1973, as amended, will be eliminated or reduced through implementation of this Strategy. Involved parties include: Colorado Department of Natural Resources, Division of Wildlife; United States Department of Interior, Bureau of Land Management.

This book was released on 1994 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Colorado River cutthroat trout (Oncorhynchus clarki pleuriticus) historically occupied portions of the Colorado River drainage in Wyoming, Colorado, Utah, Arizona, and New Mexico. Today this subspecies only occupies a fraction of its historical range is primarily located in small headwater streams. Colorado River cutthroat trout is a category 2 species (one that may be appropriate for listing as threatened or endangered) by the USDI Fish and Wildlife Service and is considered a sensitive species by Region 2 of the Forest Service. This conservation strategy is a continuation of efforts started in 1987 under a comprehensive management plan for Colorado River cutthroat trout in Wyoming"--Page ii.
Download or read book Genetic Status of Isolated Populations of Colorado River Cutthroat Trout Oncorhynchus Clarkii Pleuriticus in the North Fork Little Snake River Drainage Wyoming written by Rachel Van Horne and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In many cases of accidental isolation, the populations above the barriers have limited habitat and small population sizes that make them vulnerable to extinction and may hold evolutionary value to the species as a whole. All the isolated populations in the drainage currently have high genetic differentiation among tributaries, low genetic diversity within each tributary, a suggestion of isolation by distance, and effective population sizes that are below the recommendation for long- term persistence. This structure represents natural and anthropogenic influences, but the presence of the human-constructed barriers in the headwater tributaries puts the larger core conservation group at risk into the future. Although the genetic diversities within the populations are low, the high genetic differentiations among populations suggest that each population may have its own unique contribution to the evolutionary value to the drainage as a whole and each is important to conserve into the future.

Download or read book Cutthroat written by Pat Trotter and published by Univ of California Press. This book was released on 2008 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cutthroat tells the full story of the genuine native trout of the American West. This new edition, thoroughly revised and updated after 20 years, synthesizes what is currently known about one of our most interesting and colorful fishes, includes much new information on its biology and ecology, asks how it has fared in the last century, and looks toward its future. In a passionate and accessibly written narrative, Patrick Trotter, fly fisher, environmental advocate, and science consultant, details the evolution, natural history, and conservation of each of the cutthroat's races and incorporates more personal reflections on the ecology and environmental history of the West's river ecosystems. The bibliography now includes what may be the most comprehensive and complete set of references available anywhere on the cutthroat trout. Written for anglers, nature lovers, environmentalists, and students, and featuring vibrant original illustrations by Joseph Tomelleri, this is an essential reference for anyone who wants to learn more about this remarkable, beautiful, and fragile western native.
