Condors Shadow The Loss and Recovery of Wildlife in America

The vast majority of Amer. forests, prairies, & rivers have been logged, plowed, dammed, or developed. Hundreds of species have vanished completely & many others are now in danger. And yet, in some areas there are more acres of forests now than 100 years ago, & many lakes & rivers are cleaner than they were 20 years ago. This book attempts to make sense of these complex, & often contradictory, patterns of change. A comprehensive overview of where we stand today & how we got there. Exploring the cycles of loss & recovery that have characterized many North American ecosystems over the past two centuries & especially during the last 50 years, Wilcove examines the factors that determine a species' vulnerability to extinction.
