National Natural Landmarks Program

The National Natural Landmarks Program recognizes and encourages the conservation of sites that contain outstanding biological and geological resources.  Sites are designated by the Secretary of the Interior for their condition, illustrative character, rarity, diversity, and value to science and education.  The National Park Service administers the program and works cooperatively with landowners, managers and partners to promote conservation and appreciation of our nation's natural heritage.
