Sustainable Ecological Systems


Book Description

"This conference brought together scientists and managers from federal, state, and local agencies, along with private-sector interests, to examine key concepts involving sustainable ecological systems, and ways in which to apply these concepts to ecosystem management. Session topics were: ecological consequences of land and water use changes, biology of rare and declining species and habitats, conservation biology and restoration ecology, developing and applying ecological theory to management of ecological systems and forest health, and sustainable ecosystems to respond to human needs. A plenary session established the philosophical and historical contexts for ecosystem management."--Title page verso.

The Wolves of Mount McKinley


Book Description

In the time of Lewis and Clark, wolves were abundant throughout North America from the Arctic regions to Mexico. But man declared war on this cunning and powerful animal when cattle replaced the buffalo on the western plains, reducing the wolf's range to those few areas in the Far North where economic necessity did not call for its extinction. Between 1939 and 1941, Adolph Murie, one of North America's greatest naturalists, made a field study of the relationship between wolves and Dall sheep in Mount McKinley National Park (since renamed Denali National Park) which has come to be respected as a classic work of natural history. In this study Murie not only described the life cycle of Alaskan wolves in greater detail than has ever been done, but he discovered a great deal about the entire ecological network of predator and prey. The issues surrounding the survival of the wolf and its prey are more important today than ever, and Murie helps us understand the careful balance that must be maintained to ensure that these magnificent animals prosper. Originally available only in government publications which are long out-of-print, this account of a much maligned animal is now available in its first popular edition.
