Glacier National Park in Montana shares boundaries with Canada, an American Indian reservation, and a national forest. Along the North Fork of the Flathead River, the park also borders about 17,000 acres of private lands that are currently used for ranching, timber, and agriculture. This land is an important part of the habitat and migratory routes for several endangered species that frequent the park. These private lands are essentially the only ones available for development in the region.

With encouragement from the park, local landowners initiated a landuse planning effort to guide the future of the North Fork. The park is a partner in an interlocal agreement that calls for resourcemanaging agencies to work together and with the more than 400 private owners in the area. A draft plan has been prepared, with objective of maintaining traditional economic uses but limiting new development that would damage park resources. Voluntary action by landowners, in cooperation with the park and the county, is helping to restrict smalllot subdivisions, maintain wildlife corridors, and minimize any harmful impact on the environment.

The willingness of local landowners to participate in this protection effort may have been stimulated by concerns that congress would impose a legislative solution. Nevertheless, many local residents want to retain the existing character of the area. Meetings between park officials and landowners have led to a dramatically improved understanding of all concerns.
