An ecosystem approach to conservation is the management of natural resources using system wide concepts to ensure that all plants and animals in the ecosystem are maintained at viable levels in native habitats and basic ecosystem processes are perpetuated indefinitely (Clark and Zaunbrecher, 1987).An ecosystem approach to preservation and conservation involves protecting or restoring the function, structure, and species composition of an ecosystem, recognizing that all components are interrelated (U.S. Fish and Wildlife Service, 1994).Large-scale approaches, at the level of ecosystems and landscapes, are the most reliable way to conserve biological diversity. Such approaches avoid the problems that plague species-by-species methods that quickly exhaust time, financial resources, public patience, and scientific research resources (Franklin, 1993).Another important aspect of an ecosystem approach to preservation and conservation is the ability to integrate ecosystem protection and restoration with human values and needs as a way to strengthen the connection between economic prosperity and environmental well being. The Service recognizes the fundamental connection between human communities and the environment. To this end, the Service's approach provides a "framework" that brings together federal, state, local, and tribal governments and the public to achieve the ultimate goal of a healthy and sustainable environment. Within this framework, goals are developed based on collaboratively developed visions of desired future conditions, future conditions that integrate ecological, economic, and social...
