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.

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.

This report presents the results of the Corps of Engineers' Section 22 study of ice jam flooding in the Lower Platte River basin. The purpose of the study was to gather and analyze historical data relating to ice jams, with the intent of developing guidance that can be used to alleviate ice jam flooding at seven sites within the study area. Ice event and related information is summarized for each site. Ice event characteristics for the study area are identified and analyzed. A model for predicting the occurrence of ice jams or other ice events within the study area was developed based on data for the Platte River at North Bend, Nebraska. The model provides the minimum discharge associated with ice events for a given date, assuming a threshold value of accumulated freezing degree-days has been reached. A data collection program for future field observations was developed and placed in operation during the winter of 1993-94. General information on ice jam mitigation measures, as well as specific information on such operations as dusting and blasting, is provided. Specific recommendations include increased monitoring of ice conditions, installation of ice motion detectors and water stage recorders, and further study of nonstructural and structural mitigation measures. The use of dusting and blasting as mitigation measures is also presented. The study was divided into six phases. Phase 1 involved collection of historical information from all available data sources, published and oral. Site visits were made to each identified site. Phase 2 entailed analysis and assessment of the collected hydrological, hydraulical, meteorological and ice data.

It brings together information from several regional specialists on the major river basins of North America, presented in a large-format, full-color book. The introduction covers general aspects of geology, hydrology, ecology and human impacts on rivers. This is followed by 22 chapters on the major river basins. Each chapter begins with a full-page color photograph and includes several additional photographs within the text. These chapters feature three to five rivers of the basin/region, and cover several other rivers with one-page summaries. Rivers selected for coverage include the largest, the most natural, and the most affected by human impact. This one-of-a-kind resource is professionally illustrated with maps and color photographs of the key river basins. Readers can compare one river system to another in terms of its physiography, hydrology, ecology, biodiversity, and human impacts.* Extensive treatment provides a single source of information for North America's major rivers* Regional specialists provide authoritative information on more than 200 rivers* Full-color photographs and topographical maps demonstrate the beauty, major features, and uniqueness of each river system* One-page summaries help readers quickly find key statistics and make comparisons among rivers

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.
