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.

At a time when the health and future viability of the world's ocean is becoming a subject of growing social, political and ecological concern, Elmer A. Keen has offered a timely and thought provoking analysis of the present use of the marine fishery resources. To permit marine fisheries to remain viable, Keen argues that their current management as common resources must be changed and suggests a paradigm by which a top-to-bottom reformation of the industry to one based on ownership of the resource, coupled with profit incentives for the resource owner, might be accomplished. Revisionary when new, this book is now considered near the mainstream of thinking about the management of marine fisheries and the conservation of this important resource.

A multidisciplinary and multifaceted approach is employed to identify principal ecosystems and natural resources in the U.S. Great Plains that are at risk and that should receive priority for protection. The authors are drawn from a variety of disciplines and approaches, their ideas being presented as a pooling or harvest, rather than as a consensus. The 25 chapters provide background and in-depth discussion of multiple issues/problems related to Great Plains stewardship for future generations. The status and trends of major resources of the Great Plains within an historical, ecological and management framework are categorized according to common goals across the disciplines and can be used to make recommendations for public policy, research and development, and institutions. The challenge for residents of the Great Plains is to merge multiple ecosystem concepts to improve the environment and to improve economic vitality.
