Available in PDF, EPUB and Kindle. Book excerpt: This document focuses on the current status, distribution and range for five subspecies of cutthroat trout Oncorhynchus clarki, which are found largely on national forest system lands and ecosystems in the Rocky Mountain and Intermountain West within the U.S. from the Canadian to the Mexican border. The 5 subspecies -- Westslope, Yellowstone, Bonneville, Rio Grande, and Colorado River cutthroat trout -- are designated either species of special concern or sensitive. These subspecies are presently restricted to a fragment of their former range. Includes assessment methods, and origins and taxonomic theory. Illustrated.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This document focuses on the state of the science for five subspecies of cutthroat trout found largely on public lands in the Rocky Mountain and Intermountain West. These subspecies are restricted to a fragment of their former range, and primarily occupy small, high-elevation streams. Little is known about the three rarest subspecies (Bonneville, Colorado River, and Rio Grande cutthroat trout), and the data on the more abundant subspecies (westslope and Yellowstone cutthroat trout) were obtained from relatively few areas. The historic diversity of life history strategies has been reduced. All subspecies have suffered from introductions of nonnative fishes, habitat degradation and fragmentation, and overfishing. Current management often centers on restrictive angling regulations, barricading streams to prevent invasion by nonnative fishes, and reintroductions into streams with existing barriers.

This book was released on 2013 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native trout populations have declined over the last century because of habitat fragmentation and degradation, and the introduction/invasion of nonnative species. Now, many native species of salmonids exist in reduced ranges, primarily residing in headwater stream systems. Negative effects of predicted climate change, including increased water temperature, reduced precipitation, and increased risk of wildland fire may further jeopardize persistence of native trout populations. Headwater streams may be especially susceptible to disturbances such as debris flows. Because the probability of debris flow increases in landscapes that have recently burned, identifying susceptible areas before the occurrence of wildfire may provide information necessary to protect remnant headwater populations. Predicting the timing, extent, and severity of wildfires and subsequent precipitation and runoff events is difficult; however, it is possible to identify channels in stream networks that may be prone to debris flows. Here I present a fine-scale spatial analysis of debris flow potential in 11 high-elevation stream networks of the Colorado Rocky Mountains occupied by isolated populations of Colorado River cutthroat trout. I identified stream channels at high risk of debris flow events using models based on storm and burn scenarios, and data from geographic information systems (GIS) describing topographic, soil, and vegetation characteristics, and assessed the potential for catastrophic population disturbance given a variety of wildfire and post-wildfire storm scenarios. Results from GIS models suggest that populations in many of the study watersheds occupy areas with a high probability of experiencing post-wildfire debris flows, but the extent of their distribution and location within the stream network may provide sufficient refuge to prevent local extirpation. This method couples the spatially continuous distribution of fish and their habitat with a debris flow risk assessment model that accounts for the spatially variable properties within a watershed. Applying the risk assessment along the stream network, rather than to an entire watershed, provides a risk assessment that identifies the potential impacts of postfire debris flows within channels occupied by native fishes and other aquatic biota.
