Biodiversity and the Management of the Madrean Archipelago: The Sky Islands of Southwestern United States and Northwestern Mexico (Google eBook)
This conference brought together scientists and managers from government, universities, and private organizations to examine the biological diversity and management challenges of the unique "sky island" ecosystems of the mountains of the southwestern U.S. and northwestern Mexico. Session topics included: floristic resources, plant ecology, vertebrates, invertebrates, hydrology and riparian systems, aquatic resources, fire, conservation and management, human uses through time, and visions for the future. Illustrated.

In 1992, Reed Noss updated those f1ve and added an important sixth principle: 1. Species well distributed across their native range are less susceptible to extinction than species confined to small portions of their range. 2. Large blocks of habitat containing large populations of a target species are superior to small blocks of habitat containing small populations....
