Pub. Resources Code, § 5871

(a) The department may enter into a contract or other type of agreement with another state agency, federal agency, local agency, private organization, owner, Native American tribal government, or other interested individual or group, to assist in administering the California Natural Landmarks Program. The contract or agreement may include, but is not limited to, provisions about identification, evaluation, or monitoring a California natural landmark. However, any contract or agreement shall not authorize an entity, other than the department, to administer the provisions of this act with respect to an individual natural landmark, without the consent of the owner of the property included within the landmark.

(b) The department may conduct educational and scientific activities to disseminate information on California natural landmarks, the California Natural Landmarks Program, and benefits derived from systematic surveys of significant natural features, to the general public, interested local, state, and federal agencies, and private groups. The department may restrict information on ecologically or geologically fragile or sensitive areas, if release of that information may endanger or harm the sensitive resources.

(c) The owner of a designated California natural landmark may disseminate information about the property’s status as a natural landmark in educational and other potential materials.
