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.

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.

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 disingenuous and

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

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.
