National Natural Landmarks

National Natural Landmarks are a network of sites across the United States recognized for their outstanding biological or geological features. The program, administered by the National Park Service, aims to identify and encourage the conservation of the nation's most significant natural heritage. Designation is honorary and does not affect land ownership or mandate public access, but it highlights areas of exceptional scientific and educational value.

Overview

Established by Secretary of the Interior Stewart Udall in 1962, the program operates under the authority of the Historic Sites Act of 1935. It was created to identify and protect natural areas that illustrate the ecological and geological character of the United States, complementing other conservation efforts like the National Park System and the National Wilderness Preservation System. Landmarks range from small karst springs to expansive mountain ranges and can be located on federal, state, local, or privately owned lands. The recognition serves to promote scientific study and public appreciation of the nation's diverse natural history, from the Pleistocene epoch to contemporary ecosystems.

Designation process

The process begins with a nomination, often from scientists, conservation organizations, or government agencies, which is reviewed by the National Park Service. A rigorous evaluation follows, conducted by experts from the National Park Service and external scientists, focusing on the site's illustrative value, condition, and integrity. Key considerations include the quality of the site's natural features, its importance for scientific research, and its potential for public education. Following a positive evaluation and a mandatory landowner notification period, the Secretary of the Interior makes the final decision to designate a site. This process ensures that only areas with truly national significance, such as those containing rare fossil deposits or unique volcanic formations, receive this distinction.

Examples of landmarks

The network includes over 600 sites encompassing a vast array of natural features. Notable biological landmarks include Corkscrew Swamp Sanctuary in Florida, a prime example of old-growth bald cypress forest, and the Hawaiian Islands Humpback Whale National Marine Sanctuary. Significant geological sites feature the Kilauea volcano in Hawaii Volcanoes National Park, the La Brea Tar Pits in Los Angeles known for its Ice Age fossils, and the Great Sand Dunes in Colorado. Other exemplary landmarks are Craters of the Moon National Monument in Idaho, the Seneca Rocks in West Virginia, and the Okefenokee Swamp spanning Georgia and Florida. These sites represent the continent's ecological and geological diversity, from glacier-carved valleys in Alaska to ancient redwood groves in California.

Program administration

The National Park Service, a bureau of the Department of the Interior, manages the program through its Natural Resources Stewardship and Science directorate. Day-to-day coordination is handled by regional staff who work with landowners, state agencies like the Texas Parks and Wildlife Department, and non-profit partners such as The Nature Conservancy. While the designation does not confer direct regulatory protection, the National Park Service provides technical assistance and encourages voluntary stewardship through conservation easements or management agreements. The program also maintains a registry of sites and periodically conducts condition assessments to monitor threats from development, climate change, or invasive species, reporting its findings to Congress.

Significance and impact

The program plays a crucial role in highlighting nationally significant natural areas that might otherwise lack formal protection, fostering conservation partnerships among federal agencies like the U.S. Forest Service, state governments, and private citizens. It serves as an important tool for scientific research and education, with many landmarks located within or near institutions like the University of California or the Smithsonian Institution. By recognizing sites such as the John Day Fossil Beds or Mammoth Cave National Park, the program helps preserve irreplaceable records of Earth's history and biodiversity. This recognition often elevates local conservation efforts and raises public awareness, contributing to the broader environmental goals of acts like the Endangered Species Act and the mission of agencies including the U.S. Fish and Wildlife Service.
