Book excerpt: One of the fastest land animals on Earth (second only to the cheetah), the pronghorn can reach speeds of more than 50 miles per hour. It also is one of the most fascinating of all animals. For many people, the pronghorn was nearly as much a symbol of the American West as was the bison; for some, it still is. Eliminated from much of its historic range by the early 1900s, this unique North American big game species has experienced a remarkable recovery and now is found throughout the western United States, Canada, and northern Mexico. Thirty years in the making, Pronghorn: Ecology and Management contains the most comprehensive information on the behavior, physiology, migration, taxonomy, and management of this extraordinary animal. Full chapters are devoted to distribution, nutrition and food, diseases and parasites, ecosystem management, hunting, and much more. The principal authors--the world's preeminent pronghorn biologists, Bart W. O'Gara and Jim D. Yoakum--conclude with a thorough discussion of the future of pronghorn and their management. With 23 chapters that include contributions by 10 other wildlife professionals and more than 850 illustrations, including original artwork by Edson Fichter and Daniel P. Metz, Pronghorn: Ecology and Management is the definitive work on the species. A Wildlife Management Institute Book

Download or read book Using Science to Improve the BLM Wild Horse and Burro Program written by National Research Council and published by National Academies Press. This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.
Download or read book Prairie Ghost written by Richard E McCabe and published by University Press of Colorado. This book was released on 2011-05-18 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this lavishly illustrated volume, Richard E. McCabe, Bart W. O'Gara and Henry M. Reeves explore the fascinating relationship of pronghorn with people in early America, from prehistoric evidence through the Battle of Little Bighorn in 1876. The only one of fourteen pronghorn-like genera to survive the great extinction brought on by human migration into North America, the pronghorn has a long and unique history of interaction with humans on the continent, a history that until now has largely remained unwritten. With nearly 150 black-and-white photographs, 16 pages of color illustrations, plus original artwork by Daniel P. Metz, Prairie Ghost: Pronghorn and Human Interaction in Early America tells the intriguing story of humans and these elusive big game mammals in an informative and entertaining fashion that will appeal to historians, biologists, sportsmen and the general reader alike.
Download or read book Peninsula Watershed Historical Ecology Study written by Sean Baumgarten and published by . This book was released on 2021-07 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Peninsula Watershed has been integral to the story of San Francisco's growth ever since the Gold Rush. The rapid influx of settlers to San Francisco during the Gold Rush spurred a sudden demand for a reliable water source, which led to the formation of the Spring Valley Water Works (later purchased by the Spring Valley Water Company [SVWC]) in 1858 (Hanson 2005 ). Over the subsequent 70 years, SVWC bought up large swaths of land on the Peninsula, and constructed a complex system of dams, tunnels, and pipes to capture and transport water to San Francisco. Within the Peninsula Watershed, this system includes the Crystal Springs and San Andreas reservoirs, located in the San Andreas Creek, Laguna Creek, and Upper San Mateo Creek basins along the San Andreas Fau The City of San Francisco purchased SVWC in 1930, and today the Peninsula Watershed, managed by the San Francisco Public Utilities Commission (SFPUC), continues to be a key source of water for San Francisco and for other communities in the South and East Bay. Despite the past 150 years of reservoir construction and other hydrologic modifications, the construction of transportation and utility corridors, and the large-scale suburban development that has occurred to the east, the Peninsula Watershed has remained largely undeveloped and is managed to protect water quality, water supply, wildlife habitat, and a range of other natural and cultural resources. The watershed supports some of the largest intact remnants of contiguous habitat in the region, including extensive oak woodlands, old-growth Douglas-fir forests, serpentine grasslands, chaparral, and coastal scrub. Over the past 250 years since Spanish explorers first set foot on the watershed, however, changes in disturbance regimes and other large-scale anthropogenic modifications, including fire suppression, homesteading, livestock grazing, agriculture, tree planting, introduction of plant pathogens, spread of invasive species, and climate change, have altered vegetation dynamics and changed the distribution and structure of vegetation communities throughout the watershed. The changes have raised many questions about the historical ecology of the watershed: What was the extent, distribution, and composition of terrestrial, riparian, and wetland habitats prior to Euro-American modification? How have vegetation distributions changed over the past two centuries, and what are the implications of those changes for species support? Are there remnant patches of relatively unmodified habitat present in the watershed, or areas that are currently in a state of recovery? Where are current habitat characteristics most similar to or different from historically documented conditions? How have key natural and anthropogenic disturbance regimes and processes changed over time? The Peninsula Watershed Historical Ecology Study aims to advance understanding of landscape conditions of the Peninsula Watershed prior to major Euro-American modification, and to provide insights into the nature and drivers of vegetation change since the first Spanish explorers set foot in the watershed 250 years ago. The primary goal of the research was to examine the historical extent, distribution, and composition of terrestrial vegetation types and their trajectories of change within the watershed. To the extent possible, research also addressed historical riparian, wetland, and estuarine habitats; hydrology and sediment dynamics; wildlife support; land use history; and a range of other topics.
