National Natural Landmark is a United States federal program that recognizes and encourages the conservation of exceptional natural sites, including geological, ecological, paleontological, and biological features. The program highlights areas of outstanding scientific value located on public and private lands and seeks voluntary protection through designation rather than regulatory compulsion. It serves as an inventory and honorific system linking sites to scientific communities, conservation organizations, and federal agencies.

Overview

The National Natural Landmark program identifies and documents outstanding examples of geology of the United States, ecoregions of the United States, paleontology in the United States, biogeography, National Park Service, and other significant natural phenomena. Established to recognize exemplary landscape and habitat features across United States, the program interfaces with agencies such as the United States Fish and Wildlife Service, United States Forest Service, Bureau of Land Management, and institutions like the Smithsonian Institution, United States Geological Survey, and major universities. Designated sites include diverse types such as cave, glacier, dune, wetland, prairie, old-growth forest, coral reef, and fossil bed examples that contribute to scientific research tied to fields represented by the National Academy of Sciences and professional societies.

History

The program originated from mid-20th-century conservation initiatives influenced by figures and entities including the National Park Service, the Wilderness Act, and recommendations from commissions with ties to the National Research Council and President John F. Kennedy administration policymaking. Formalized in regulations adopted during the 1960s under the auspices of the National Park Service and subsequent administrations, the program evolved alongside landmark conservation milestones such as the National Trails System Act and interactions with institutions like the Sierra Club, The Nature Conservancy, and the Audubon Society. Over time, designation procedures and scientific evaluation protocols drew from methodologies employed by the United States Geological Survey, the American Association for the Advancement of Science, and university departments at Harvard University, University of California, Berkeley, and Yale University.

Criteria and Designation Process

Sites are evaluated using criteria developed with expert input from organizations including the National Academy of Sciences, Geological Society of America, Ecological Society of America, and specialist institutions such as the American Museum of Natural History and Field Museum of Natural History. Technical assessments consider factors like representativeness, condition, rarity, and diversity measured against comparable features at sites managed by entities such as the National Park Service, Smithsonian Institution, United States Forest Service, and major research universities. The designation process involves inventory, peer review, landowner notification, and recommendation by the National Park Service to the Secretary of the Interior. Throughout, partnerships with stakeholders including the Nature Conservancy, National Audubon Society, Trust for Public Land, and state natural heritage programs are central to evaluation and outreach.

Management and Protection

Designation does not change ownership but establishes cooperative mechanisms among the National Park Service, state agencies like the California Department of Parks and Recreation, local governments such as the City of New York, and private organizations including The Nature Conservancy and academic institutions like University of Michigan. Management tools rely on voluntary conservation easements, technical assistance from the United States Fish and Wildlife Service and United States Forest Service, and funding or grants influenced by legislation and programs associated with agencies like the Environmental Protection Agency and foundations linked to the Smithsonian Institution. Legal frameworks and agreements sometimes reference standards informed by the Endangered Species Act and consultations with institutions such as the National Oceanic and Atmospheric Administration for marine or coastal components.

Notable Landmarks

Designated examples illustrate the program’s geographic and scientific breadth: Mammoth Cave National Park–area karst and cave systems referenced by researchers at the National Speleological Society; Everglades National Park–associated wetlands studied by the South Florida Water Management District and University of Miami; Bandelier National Monument–volcanic and archaeological landscapes linked to the National Park Service research network; Badlands National Park–paleontological formations examined by the South Dakota School of Mines and Technology; and Mount St. Helens National Volcanic Monument–volcanology sites researched by the United States Geological Survey and University of Washington. Other prominent examples include sites connected to Yellowstone National Park, Grand Canyon National Park, Joshua Tree National Park, Apostle Islands National Lakeshore, and Isle Royale National Park, each studied by regionally associated universities and scientific societies.

Challenges and Conservation Efforts

Conservation of designated sites faces pressures studied by entities like the United States Geological Survey, National Oceanic and Atmospheric Administration, Environmental Protection Agency, and academic research centers at Stanford University, Massachusetts Institute of Technology, and University of California, Davis. Threats include invasive species documented by the USDA Animal and Plant Health Inspection Service, land-use change tracked by state departments such as the New York State Department of Environmental Conservation, and climate-driven impacts assessed by the Intergovernmental Panel on Climate Change and climate centers like the National Center for Atmospheric Research. Responding strategies involve collaborative restoration projects with nongovernmental organizations including The Nature Conservancy and National Audubon Society, scientific monitoring coordinated through the National Park Service and United States Geological Survey, and outreach programs with tribal authorities such as the Bureau of Indian Affairs and indigenous communities. Continuous research, partnership building, and targeted funding from philanthropic institutions underpin efforts to sustain the scientific and conservation values of designated sites.
