This change is apparent across the globe, on every continent and in every ecosystem. As this century draws to a close, however, an increasing number of scientists, citizens and government representatives are attempting to curb the erosion of biological diversity and halt the unrestrained human behavior that threatens our fragile planet. One of the principal mechanisms for preventing the destruction of biological diversity is through the protection of representative ecosystems in reserve complexes. These reserves must be of sufficient size and variety to allow natural ecological processes to continue in the face of internal and external forces of change. The idea of protection through the identification and design of nature reserve systems has been around for over a century, beginning in 1872 with the designation of the Yellowstone region in the United States as the world's first national park. Yellowstone was set aside to prevent the destruction of the region's landscapes, wildlife and unique geological features from short-sighted development. Since the creation of Yellowstone National Park, thousands of parks, wilderness areas, and other biological reserves have been created around the world. The intent behind setting aside these areas has expanded considerably beyond preservation of scenic beauty to encompass the protection of biological diversity from the genetic to the landscape level. In the Rocky Mountains of Canada and the United States, there is an opportunity to identify and protect significant areas of North America's remaining intact temperate ecosystems. But this process of protection needs to be driven by the best available biological knowledge, tempered by a realistic commitment to implement aggressive protection proposals once they have been prepared. This means forging a strong link between science and politics. Such a link must use the sophisticated models and perspective of conservation biology, driven by the political skill and knowledge of grassroots conservation activists working to protect the ecosystems of their home regions. This research paper will review approaches for effectively using both of these powerful tools in order to propose a protection strategy for the Rocky Mountains of British Columbia and Alberta, compatible and linked with existing reserve system proposals in Canada and the United States (see Map 1, next page).

Driving the ecological reserve planning process is the developing discipline of conservation biology, a branch of biological science concerned with the development of ecological theory and its application to the protection of biological diversity at all levels {Soule 19 86). Conservation biology is rapidly gaining authority in the process of designing biological or ecosystem reserves as refuges for not only individual species of plants and animals, but for the processes of natural ecological function as well. Biologists are determining the minimum habitat requirements for numerous species' survival, and identifying the last remaining functioning land areas that may sustain intact species assemblages. Throughout the world, areas are being identified that retain sufficient size and natural function to sustain natural biological processes in perpetuity. In the Earth's temperate regions, many biological systems have been fragmented and destroyed. Given the dense concentration of human population within the temperate band, it is becoming more difficult to identify areas where biological systems still function naturally. In North America, the western mountain region harbors a group of relatively intact ecosystem complexes. The Rocky Mountains of the United States and Canada contain large areas of remote native forest, riparian, and alpine habitat. These areas are under intense pressure from human encroachment and face a severe threat of destructive
