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 Plowed Under, Andrew P. Duffin traces the transformation of the Palouse region of Washington and Idaho from land thought unusable and unproductive to a wealth-generating agricultural paradise, weighing the consequences of what this progress has wrought. During the twentieth century, the Palouse became synonymous with wheat, and the landscape was irrevocably altered. At the dawn of the twenty-first century, native vegetation is almost nonexistent, stream water is so dirty that it is often unfit for even livestock, and 94 percent of all land has been converted to agriculture. Commercial agriculture also created a less noticeable ecological change: soil erosion. While common to industrial agriculture nationwide, topsoil loss evoked different political and social reactions in the Palouse. Farmers all over the nation take pride in their freedom and independence, but in the Palouse, Duffin shows, this mentality - a remnant of an older agrarian past - has been taken to the extreme and is partly responsible for erosion problems that are among the worst in the nation. In the hope of charting a better, more sustainable future, Duffin argues for a candid look at the land, its people, their decisions, and the repercussions of those decisions. As he notes, the debate is not over whether to use the land, but over what that use will look like and its social and ecological results.

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.
