Audubon Wildlife Report 1987 covers important events that highlighted wildlife conservation in 1986. This book is an attempt by the National Audubon Society to gather together much of the diverse data about federal wildlife-policy administration, providing a vast array of data on federal wildlife management and comparative tables on the budgeting process. This text also examines many federal wildlife programs, from the migratory bird protection program, which in a sense gave birth to the federal role in wildlife conservation, to the endangered species program, called as the most important wildlife conservation effort in the world. This publication is valuable to conservationists and individuals interested in federal and state wildlife management.
