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 inter local 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.

答案解析：
16. B) 这是一道主旨题。通过阅读文章可知，为了保护冰川国家公园的濒危物种和资源，公园当局和地方土地所有者制订了限制土地使用计划，故答案为B。
17. D) 这是一道细节题。根据第一段第三句“This land is an important part of the habitat and migratory routes for several endangered species that frequent the park.”(这片土地是非常重要的，因为这里是几种经常光顾此公园的濒危物种的栖息地和迁徙路线。)可知选项D为正确答案。
18. C) 根据第二段可知，公园当局和地方土地所有者密切合作来保护资源，因此他们的关系是"cooperative" (合作性的)。
