Book Description
The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.

Book Description
The Great Plains were once among the greatest grasslands on the planet. But as the United States and Canada grew westward, the Plains were plowed up, fenced in, overgrazed, and otherwise degraded. Today, this fragmented landscape is the most endangered and least protected ecosystem in North America. But all is not lost on the prairie. Through lyrical photographs, essays, historical images, and maps, this beautifully illustrated book gets beneath the surface of the Plains, revealing the lingering wild that still survives and whose diverse natural communities, native creatures, migratory traditions, and natural systems together create one vast and extraordinary whole. Three broad geographic regions in Great Plains are covered in detail, evoked in the unforgettable and often haunting images taken by Michael Forsberg. Between the fall of 2005 and the winter of 2008, Forsberg traveled roughly 100,000 miles across 12 states and three provinces, from southern Canada to northern Mexico, to complete the photographic fieldwork for this project, underwritten by The Nature Conservancy. Complementing Forsberg’s images and firsthand accounts are essays by Great Plains scholar David Wishart and acclaimed writer Dan O’Brien. Each section of the book begins with a thorough overview by Wishart, while O’Brien—a wildlife biologist and rancher as well as a writer—uses his powerful literary voice to put the Great Plains into a human context, connecting their natural history with man’s uses and abuses. The Great Plains are a dynamic but often forgotten landscape—overlooked, undervalued, misunderstood, and in desperate need of conservation. This book helps lead the way forward, informing and inspiring readers to recognize the wild spirit and splendor of this irreplaceable part of the planet.

Book Description
Nebraska sits at the nexus of continental bird migration and serves as a home?either permanently or seasonally?for nearly 450 species. Major migratory routes pass through the state, creating numerous opportunities to observe the great variety of North American bird species. The annual crane migrations in spring are legendary, and other key events include winter concentrations of bald eagles, flocks of up to thirty thousand grebes, mergansers, and gulls at Lake McConaughy in late fall, and incredible concentrations of waterfowl in the Rainwater Basin in early spring.øBirds of Nebraska captures the variety of Nebraska's ornithological possibilities in a style useful to hobbyists and professionals alike. For the first time in Nebraska ornithology, the authors have provided an exhaustive summary of state bird records compiled into concise but readable accounts of all species of birds reported in the state. This work covers taxonomy, early and late migration dates, high counts, nesting areas, and likely viewing locations.

Book Description
George Bent, the son of William Bent, one of the founders of Bent's Fort on the Arkansas near present La Junta, Colorado, and Owl Woman, a Cheyenne, began exchanging letters in 1905 with George E. Hyde of Omaha concerning life at the fort, his experiences with his Cheyenne kinsmen, and the events which finally led to the military suppression of the Indians on the southern Great Plains. This correspondence, which continued to the eve of Bent's death in 1918, is the source of the narrative here published, the narrator being Bent himself. Almost ninety years have elapsed since the day in 1930 when Mr. Hyde found it impossible to market the finished manuscript of the Bent life down to 1866. (The Depression had set in some months before.) He accordingly sold that portion of the manuscript to the Denver Public Library, retaining his working copy, which carries down to 1875. The account therefore embraces the most stirring period, not only of Bent's own life, but of life on the Plains and into the Rockies. It has never before been published. It is not often that an eyewitness of great events in the West tells his own story. But Bent's narrative, aside from the extent of its chronology (1826 to 1875), has very special significance as an inside view of Cheyenne life and action after the Sand Creek Massacre of 1864, which cost so many of the lives of Bent's friends and relatives. It is hardly probable that we shall achieve a more authentic view of what happened, as the Cheyennes, Arapahos, and Sioux saw it.
