(a) The Secretary shall maintain a State Registry of voluntarily protected natural areas to be called the North Carolina Registry of Natural Heritage Areas. Registration of natural areas shall be accomplished through voluntary agreement between the owner of the natural area and the Secretary. State-owned lands may be registered by agreement with the agency to which the land is allocated. Registration agreements may be terminated by either party at any time, and termination removes the area from the Registry.
(b) A natural area shall be registered when an agreement to protect and manage the natural area for its specified natural heritage resource value has been signed by the owner and the Secretary. The owner of a registered natural area shall be given a certificate signifying the inclusion of the area in the Registry.
