Book Description
Grasslands provide both ecological and economic benefits. The importance of grasslands lies not only in the areas they cover, but also in the diversity of environmental benefits they produce. The lands provide forage for livestock, water for urban and rural uses, flood protection, wildlife habitat, purification of air, and carbon sequestration. The lands also provide aesthetic values and open space. This book discusses the Grasslands Reserve Program (GRP), which provides assistance to landowners and operators to protect grazing uses and related conservation values on eligible private range and pasture lands. The program emphasises support of grazing operations, maintaining and improving plant and animal biodiversity, and protecting grasslands and shrublands under threat of conversion to cropping, urban development, and other non-grazing uses.
The Changing Prairie

Book Description
Grasslands have figured prominently in our North American heritage. Prairies first provided significant barriers to westward expansion, then offered both economic and sociological opportunity, as well as heartache, for settlers. Many artists have gained significant inspiration from the beauty as well as the harshness of these regions and its biota. And, because of ideal climate and soil conditions, these grasslands have provided the agricultural foundation upon which much of the growth and stability of the United States economy rests. Yet, many see North America prairies as beautiful only when manipulated or exploited--green croplands or manicured park lawns are attractive, whereas native grasslands are "those ugly weeds." In the past, plowing virgin prairie could be easily defended on both economic and sociological grounds. And historically, North American prairies must have seemed threatening in both their wildness and vastness. But preservation of these prairies is now an urgent need. This book describes the ecology of the North American prairie and urges conservation measures to protect the remaining North American grasslands. It provides non-economic arguments for the value of prairies, presents a current synthesis of prairie ecology to facilitate the best possible management, and deftly summarizes conservation and management issues, pointing out the costs and benefits of alternative actions. By approaching its subject from a variety of perspectives, including ethical and aesthetic considerations, the book will appeal to environmentalists and conservationists as well as to ecologists, botanists, and conservation biologists.
Ecological Regions of North America

ISBN:
Category : Biogeography
Languages : en
Pages : 96
Book Description
This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.
