The National Natural Landmarks (NNL) Program recognizes and encourages the conservation of outstanding examples of the natural history of the United States. [1] It is the only national natural areas program that identifies and recognizes the best examples of biological and geological features in both public and private ownership. The program was established on May 18, 1962, by United States Secretary of the Interior Stewart Udall.

Contents

The program aims to encourage and support voluntary preservation of sites that illustrate the geological and ecological history of the United States. It also hopes to strengthen the public's appreciation of the country's natural heritage. As of January 2021, 602 sites have been added to the National Registry of Natural Landmarks. [2] The registry includes nationally significant geological and ecological features in 48 states, American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands.

The National Park Service administers the NNL Program and if requested, assists NNL owners and managers with the conservation of these important sites. Land acquisition by the federal government is not a goal of this program. National Natural Landmarks are nationally significant sites owned by a variety of land stewards, and their participation in this federal program is voluntary.

The legislative authority for the National Natural Landmarks Program stems from the Historic Sites Act of August 21, 1935 (49 Stat. 666, 16 U.S.C. 641); the program is governed by federal regulations. [3] The NNL Program does not have the protection features of Section 106 of the National Historic Preservation Act of 1966. Thus, designation of a National Natural Landmark presently constitutes only an agreement with the owner to preserve, as far as possible, the significant natural values of the site or area. Administration and preservation of National Natural Landmarks is solely the owner's responsibility. Either party may terminate the agreement after they notify the other.

Designation

The NNL designation is made by the Secretary of the Interior after in-depth scientific study of a potential site. All new designations must have owner concurrence. The selection process is rigorous: to be considered for NNL status, a site must be one of the best examples of a natural region's characteristic biotic or geologic features. Since establishment of the NNL program, a multi-step process has been used to designate a site for NNL status. Since 1970, the following steps have constituted the process.

  1. A natural area inventory of a natural region is completed to identify the most promising sites.
  2. After landowners are notified that the site is being considered for NNL status, a detailed onsite evaluation is conducted by scientists other than those who conducted the inventory. [note 1]
  3. The evaluation report is peer reviewed by other experts to assure its soundness.
  4. The report is reviewed further by National Park Service staff.
  5. The site is reviewed by the Secretary of the Interior's National Park Advisory Board to determine that the site qualifies as an NNL.
  6. The findings are provided to the Secretary of the Interior who approves or declines.
  7. Landowners are notified a third time informing them that the site has been designated an NNL.

Prospective sites for NNL designation are terrestrial and aquatic ecosystems; geological features, exposures, and landforms that record active geological processes or portions of earth history; and fossil evidence of biological evolution. Each major natural history "theme" can be further subdivided into various sub-themes. For example, sub-themes suggested in 1972 for the overall theme "Lakes and ponds" included large deep lakes, large shallow lakes, lakes of complex shape, crater lakes, kettle lake and potholes, oxbow lakes, dune lakes, sphagnum-bog lakes, lakes fed by thermal streams, tundra lakes and ponds, swamps and marshy areas, sinkhole lakes, unusually productive lakes, and lakes of high productivity and high clarity.

Ownership

The NNL program does not require designated properties to be owned by public entities. Lands under almost all forms of ownership or administration have been designated—federal, state, local, municipal, and private. Federal lands with NNLs include those administered by the National Park Service, U.S. Forest Service, Bureau of Land Management, Bureau of Reclamation, Fish and Wildlife Service, Air Force, Marine Corps, Army Corps of Engineers, Navy, and others.

Some NNL have been designated on lands held by Native Americans or tribes. NNLs also have been designated on state lands that cover a variety of types and management, such as forest, park, game refuge, recreation area, and preserve. Private lands with NNLs include those owned by universities, museums, scientific societies, conservation organizations, land trusts, commercial interests, and private individuals. Approximately 52% of NNLs are administered by public agencies, more than 30% are entirely privately owned, and the remaining 18% are owned or administered by a mixture of public agencies and private owners.

Access

Participation in the NNL Program carries no requirements regarding public access. The NNL registry includes many sites of national significance that are open for public tours, but others are not. Since many NNLs are located on federal and state property, permission to visit is often unnecessary. Some private property may be open to public visitation or just require permission from the site manager. On the other hand, some NNL private landowners desire no visitors whatever and might even prosecute trespassers. The reasons for this viewpoint vary: potential property damage or liability, fragile or dangerous resources, and desire for solitude or no publicity.

Property status

NNL designation is an agreement between the property owner and the federal government. NNL designation does not change ownership of the property nor induce any encumbrances on the property. NNL status does not transfer with changes in ownership.

Participation in the NNL Program involves a voluntary commitment on the part of the landowner(s) to retain the integrity of their NNL property as it was when designated. If "major" habitat or landscape destruction is planned, participation in the NNL Program by a landowner would be ingenuous and meaningless.

The federal action of designation imposes no new land use restrictions that were not in effect before the designation. It is conceivable that state or local governments on their own volition could initiate regulations or zoning that might apply to an NNL. However, as of 2005 no examples of such a situation have been identified. Some states require planners to ascertain the location of NNLs.

A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property.

National Historic Landmark Building, area, or object officially recognized by the US govt. for historical significance

A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Only some 2,500 (~3%) of over 90,000 places listed on the country's National Register of Historic Places are recognized as National Historic Landmarks.

Protected areas of the United States Legally protected land, eg national parks

The protected areas of the United States are managed by an array of different federal, state, tribal and local level authorities and receive widely varying levels of protection. Some areas are managed as wilderness, while others are operated with acceptable commercial exploitation. As of 2022, the 42,826 protected areas covered 1,235,486 km2 (477,024 sq mi), or 13 percent of the land area of the United States. This is also one-tenth of the protected land area of the world. The U.S. also had a total of 871 National Marine Protected Areas, covering an additional 1,636,523 km2 (631,865 sq mi), or 19 percent of the total marine area of the United States.

The Forest Legacy Program was established in the 1990 United States farm bill to protect environmentally important forest lands that are threatened by conversion to nonforest uses. It provides federal funding for conservation easements and fee simple purchases.

The Historic Preservation Fund (HPF) provides financial support for historic preservation projects throughout the United States. The fund is administered by the National Park Service (NPS), pursuant to the National Historic Preservation Act of 1966 (NHPA).

Lake Agassiz Peatlands Natural Area is a 25,411-acre (10,283 ha) National Natural Landmark located in Koochiching County, Minnesota. Designated in November 1965 under the Historic Sites Act, its ownership and oversight are provided by the National Park Service of the United States. This designation from the United States Secretary of the Interior, gives it recognition as an outstanding example of the nation's natural history. The designation describes it as

An example of the extensive peatlands occupying the bed of ancient glacial Lake Agassiz, illustrating the process of peat accumulation over about 11,000 years. The area contains Myrtle Lake Bog, which developed contrary to the usual successional process of lake filling, and is an excellent example of both raised and string bogs.
