The frontier images of America embrace endless horizons, majestic herds of native ungulates, and romanticized life-styles of nomadie peoples. The images were mere reflections of vertebrates living in harmony in an ecosystem driven by the unpre dictable local and regional effects of drought, frre, and grazing. Those effects, often referred to as ecological "disturbanees," are rather the driving forces on which species depended to create the spatial and temporal heterogeneity that favored ecological prerequisites for survival. Alandscape viewed by European descendants as monotony interrupted only by extremes in weather and commonly referred to as the "Great American Desert," this country was to be rushed through and cursed, a barrier that hindered access to the deep soils of the Oregon country, the rich minerals of California and Colorado, and the religious freedom sought in Utah. Those who stayed (for lack of resources or stamina) spent a century trying to moderate the ecological dynamics of Great Plains prairies by suppressing fires, planting trees and exotic grasses, poisoning rodents, diverting waters, and homogenizing the dynamies of grazing with endless fences-all creating bound an otherwise boundless vista. aries in Historically, travelers and settlers referred to the area of tallgrasses along the western edge of the deciduous forest and extending midway across Kansas as the "True Prairie. " The grasses thlnned and became shorter to the west, an area known then as the Great Plains.

In Wildlife of Nebraska: A Natural History, Paul A. Johnsgard surveys the variety and biology of more than six hundred Nebraska species. Narrative accounts describe the ecology and biology of the state’s birds, its mammals, and its reptiles and amphibians, summarizing the abundance, distributions, and habitats of this wildlife. To provide an introduction to the state’s major ecosystems, climate, and topography, Johnsgard examines major public-access natural areas, including national monuments, wildlife refuges and grasslands, state parks and wildlife management areas, and nature preserves. Including more than thirty-five line drawings by the author along with physiographic, ecological, and historical maps, Wildlife of Nebraska is an essential guide to the wildlife of the Cornhusker State.

The area of native prairie known as the Great Plains once extended from Canada to the Mexican border and from the foothills of the Rocky Mountains to western Indiana and Wisconsin. Today the declines in prairie landscape types, estimated to be as high as 99%, exceed those of any other major ecosystem in North America. The overwhelming loss of landscape and accompanying loss of species constitute a real threat to both ecological and human economic health.Prairie Conservation is a comprehensive examination of the history, ecology, and current status of North American grasslands. It presents for the first time in a single volume information on the historical, economic, and cultural significance of prairies, their natural history and ecology, threats, and conservation and restoration programs currently underway. Chapters cover: environmental history of the Great Plains the economic value of prairie prairie types -- tallgrass, mixed grass, shortgrass, wetlands -- and the ecological processes that sustain each type prairie fauna -- invertebrates, fish and other aquatic creatures, amphibians and reptiles, birds, and mammals conservation programs such as the Great Plains Partnership, Canada's Prairie Conservation Action Plan, the U.S. Prairie Pothole Joint Venture, and others The book brings together knowledge and insights from a wide range of experts to describe and explain the importance of prairies and to position them in the forefront of North American conservation efforts. Praire Conservation is an essential reference for anyone interested in prairie ecology and conservation and will play a critical role in broadening our awareness and understanding of prairie ecosystems.
