Pub. Resources Code, § 5019.65

State reserves consist of areas embracing outstanding natural or scenic characteristics or areas containing outstanding cultural resources of statewide significance. State reserve units may be established in the terrestrial or nonmarine aquatic (lake or stream) environments of the state and shall be further classified as one of the following types:

(a) State natural reserves, consisting of areas selected and managed for the purpose of preserving their native ecological associations, unique faunal or floral characteristics, geological features, and scenic qualities in a condition of undisturbed integrity. Resource manipulation shall be restricted to the minimum required to negate the deleterious influence of man.

Improvements undertaken shall be for the purpose of making the areas available, on a day use basis, for public enjoyment and education in a manner consistent with the preservation of their natural features. Living and nonliving resources contained within state natural reserves shall not be disturbed or removed for other than scientific or management purposes.

(b) State cultural reserves, consisting of areas selected and managed for the purpose of preserving and protecting the integrity of places that contain historic or prehistoric structures, villages, or settlements, archaeological features, ruins, artifacts, inscriptions made by humans, burial grounds, landscapes, hunting or gathering sites, or similar evidence of past human lives or cultures. These areas may also be places of spiritual significance to California Native Americans. Within state cultural reserves, the highest level of resource protection shall be sought. Improvements may be undertaken for the purpose of providing public access, enjoyment, and education, and for cultural resource protection. Improvements made for the purpose of cultural resource protection shall take into account the possible need for access to the site for ceremonial or spiritual purposes. Living and nonliving resources contained within state cultural reserves may be used for ceremonial or spiritual purposes, consistent with other laws, and if the use is not harmful to threatened or endangered species or to the cultural resources intended for protection by this designation. Management actions shall be consistent with the preservation of cultural resources and with federal and state laws.
