Measuring the Health of our National Parks: Rock Creek Park
The Inventory and Monitoring (I&M) Program has subdivided the 270 National Park units with significant natural resources into 32 Networks. All of the parks within a Network share similar natural resource challenges. The purpose of these Networks is to conduct long-term resource monitoring. The National Capital Region Netwok (NCRN) consists of 11 parks within Maryland, Virginia, West Virginia, and the District of Columbia. These parks were established for their cultural and recreational value; however, they provide important natural oases in an increasingly urban context.
