"A biological survey for the nation" . . . . . . . . . . . "Our country has long recognized the importance of its biological resources but we often lack sufficient scientific knowledge to make wise decisions. This realization has led to calls for new ways of providing this information, including the formation of a national biological survey. This volume discusses key issues and problems for which an improved assessment of the nation's biological resources is needed; the kinds of efforts in research and information management needed to create that assessment; and how government, private organizations, and individuals can work together to meet the needs identified. Policymakers, resource managers, public interest groups, and researchers will find this book useful as they participate in the national dialogue on this topic and take actions to implement the needed survey activities." .
