THE NATIONAL PARK SERVICE: A STEWARD FOR THE NATION'S GEOLOGICAL HERITAGE
Currently, the National Park system includes 162 units with significant geologic resources, and of those, 85 were solely established for geology. Seven National Parks have been recognized by UNESCO as having international geologic significance. In additional to the geologic wonders in national parks, the Park Service is responsible for administering the National Natural Landmarks program. More than 100 landmarks have been recognized for geologic significance, most are outside of NPS lands. Together, the National Natural Landmarks and the National Parks constitute a National program that recognizes geologic heritage.
In 1998, a law was passed that mandated the Park Service to use science based decision-making to guide its management activities. The National Park Service is beginning to inventory all of its significant geologic features, paleontological sites, and caves. In a number of parks, geologic monitoring has also been established to track changes in geologic processes.
The trend toward increased recognition of the importance of geologic heritage is likely to continue as the public and policy-makers become more aware of its significance. The service is working with State and local governments, as well as the U.S. Geological Survey and the geologic community to build its geologic heritage programs. We anticipate that these collective partnerships will open opportunities for the geological societies, academic organizations, and the geologic community at large to become involved in recommending geologic heritage sites and in their long-term conservation.
