<br />4 <br /> <br />Whenever a change in agricultural or forestry practices provides <br />food or cover for wildlife, a variety of species are usually quick to <br />adjust to the new resources. canada geese winter by the thousands in <br />areas where there is little water or natural food but where corn has <br />been spilled during the harvest in extensive fields. Similar <br />responses to new sources of food or shelter can be observed in <br />songbirds and other nongame species. In contrast, species can be <br />eliminated by agricultural practices that fragment their habitats. <br />Some insect-eating songbirds need large forested areas during the <br />breeding season, and practices that break up forests are likely to be <br />detrimental to them. <br /> <br />THE STRUCTURE OF THIS REPORT <br /> <br />This report falls roughly into two parts. The first part, Chapters 2 <br />through 5, identifies the major agricultural trends in the united <br />States. Chapter 2 focuses on the incorporation of wildlife values in <br />land and water use decisions and the measurement and valuation issues <br />associated with the private and public policy decisions that will <br />affect the nature of the impacts of agricultural trends. Chapter 3 <br />discusses the major forces that shape agricultural trends particularly <br />important to wildlife habitat. Chapter 4 provides information about <br />land and water resources and discusses trends for future land and <br />water use as well as the quality and availability of these resources. <br />Chapter 5 examines agricultural and forestry management practic~s that <br />affect fish and wildlife habitats and the likelihood of their <br />continued use. The second part, Chapters 6 through 11, examines the <br />impacts of the identified trends on each of the major habitat types. <br /> <br />LITERATURE CITED <br /> <br />Brokaw, H.P., ed. 1978. wildlife and America.
