Publisher's Synopsis
The mission of the National Park Service (NPS) is "to conserve unimpaired the natural and cultural resources and values of the national park system for the enjoyment of this and future generations" (NPS 1999). To achieve that goal, and as a result of the Natural Resource Challenge, 270 parks in the national park system were organized into 32 Inventory and Monitoring (I&M) Networks. One of those networks, the Eastern Rivers and Mountains Network (ERMN), includes nine parks in New Jersey, New York, Pennsylvania, and West Virginia.
