The Fragmented Forest: Island Biogeography Theory and the Preservation of Biotic Diversity (Chicago Original Paperback)

In this poineering application of island biogeography theory, Harris presents an alternative to current practices of timber harvesting. "Harris pulls together many threads of biological thinking about islands and their effect on plant and animal survival and evolution. He weaves these threads into a model for managing forest lands in a manner that might serve both our short-term economic and social needs as well as what some people feel is our ancient charge to be steward of all parts of creation."—__American Forests__ __Winner of the 1986 Wildlife Society Publication Award__ Part 1: Problem Setting.
