23.27 Natural areas; definitions; importance; inventory; acquisition; sales.
(1) Definitions. As used in this section and ss. 23.28 and 23.29:
(a) “Council" means the natural areas preservation council.
(b) “Dedicated state natural areas" means land accepted and recorded for dedication under the Wisconsin natural areas heritage program as provided under s. 23.29 (16).
(c) “Dedication" means the transfer of land or a permanent interest in land to the state of Wisconsin to be held in trust for the people of Wisconsin by the department in a manner which ensures the protection and stewardship of the area and natural values associated with the area. “Dedication" also means the binding unilateral declaration by the state that land under the ownership of the state is to be held in trust for the people of Wisconsin by the department in a manner which ensures the protection and stewardship of the area and natural values associated with the area.
(d) “Designated state natural area" means a natural area designated as a state natural area under s. 23.28 (1).
(e) “Natural area" means an area of land or water which has educational or scientific value or is important as a reservoir of the state's genetic or biologic diversity and includes any buffer area necessary to protect the area's natural values. Frequently, “natural areas" are important as a reserve for native biotic communities. Frequently, “natural areas" provide habitat for endangered, threatened or critical species or for species of special concern to scientists. In some cases, “natural areas" include areas with highly significant geological or archaeological features. Generally, “natural areas" are areas which largely escaped unnatural environmental disturbance or which exhibit little evidence of recent environmental disturbance so that recovery of natural conditions has occurred.
(f) “Natural values" includes any important values and characteristics listed under sub. (2) (a) to (i) which enable an area to be considered a natural area.
(g) “Research natural area" means all or part of a state natural area identified by the department, with the advice of the council, as a natural area especially suitable or important for scientific research.
(h) “State natural area", unless otherwise limited, means any designated state natural area or dedicated state natural area.
(i) “Stewardship" means the continuing obligation to provide the necessary maintenance, management, protection, husbandry and support for a natural area and natural values associated with that area.
(2) Importance. The department, with the advice of the council, shall maintain a system to evaluate the importance of natural areas. The system shall include standards for determining low, high and critical levels of importance for natural areas. This system shall consider the following natural values:
(a) The value of the area as a preserve or reservoir which exhibits an outstanding or high quality example of a native plant or animal community.
(b) The value of the area as a preserve or reservoir for any endangered, threatened or critical species or for a species of special concern to scientists.
(c) The value of the area as a preserve or reservoir of genetic or biological diversity.
(d) The degree to which the area was subject to unnatural environmental disturbance and the degree of recovery.
(e) The value of the area for educational or scientific research purposes and as a reference site for comparison with areas subjected to environmental disturbance.
(f) The value of the area for educational or scientific research purposes because of important or unusual characteristics.
(g) The significance or uniqueness of the area in the locality, region and state.
(h) The existence of highly significant geological or archaeological features.
(i) The value of the area for public educational purposes, including the value of the area in promoting public awareness, appreciation, understanding and respect for the state's natural heritage.
(3) Natural heritage inventory program.
(a) Duties. The department shall conduct a natural heritage inventory program. The department shall cooperate with the department of administration under s. 16.967 in conducting this program. This program shall establish a system for determining the existence and location of natural areas, the degree of endangerment of natural areas, an evaluation of the importance of natural areas, information related to the associated natural values of natural areas, and other information and data related to natural areas. This program shall establish a system for determining the existence and location of native plant and animal communities and endangered, threatened, and critical species, the degree of endangerment of these communities and species, the existence and location of habitat areas associated with these communities and species, and other information and data related to these communities and species. This program shall establish and coordinate standards for the collection, storage, and management of information and data related to the natural heritage inventory.
(b) Access to information; fees. The department shall make information and data from the natural heritage inventory program available to any individual or public or private agency for research, educational, environmental, land management or similar authorized purposes. The department may establish a fee to be collected to recover the actual cost of collecting, storing, managing, compiling and providing this information and data. The department may reduce or waive the fee established under this paragraph if the department determines that a waiver or reduction of the fee is in the public interest. The natural heritage inventory and related information and data are not subject to s. 19.35 and the department may refuse to release information or data for any purpose which is not authorized.
(4) Natural areas land acquisition; continuing commitment. It is the intent of the legislature to continue natural areas land acquisition activities from moneys available from the appropriations under ss. 20.370 (7) (fa) and 20.866 (2) (ta), (ts) and (tz). This commitment is separate from and in addition to the commitment to acquire natural areas under the Wisconsin natural areas heritage program. Except as provided in s. 23.0915 (2), the department may not expend from the appropriation under s. 20.866 (2) (tz) more than $1,500,000 in each fiscal year for natural areas land acquisition activities under this subsection and for grants for this purpose under s. 23.096.
(5) Natural areas land acquisition; commitment under the Wisconsin natural areas heritage program.

This commitment is separate from and in addition to the continuing commitment under sub. (4). Moneys available from the appropriations under ss. 20.370 (1) (fu) and 20.866 (2) (ta), (tt), and (tz) under the Wisconsin natural areas heritage program may not be used to acquire land through condemnation. The department may not acquire land under this subsection unless the land is suitable for dedication under the Wisconsin natural areas heritage program and upon purchase or as soon after purchase as practicable the department shall take all necessary action to dedicate the land under the Wisconsin natural areas heritage program. Except as provided in s. 23.0915 (2), the department may not expend from the appropriation under s. 20.866 (2) (tz) more than $500,000 in each fiscal year for natural areas land acquisition activities under this subsection and for grants for this purpose under s. 23.096.
(6) Sale; credit. Moneys received by the state from the sale of any area on state-owned land under the department's management or control which is withdrawn from the state natural areas system shall be credited to the appropriation under s. 20.370 (1) (fu). An amount equal to the value of any area on state-owned land under the department's management or control which is withdrawn from the state natural areas system but remains in state ownership shall be credited to the appropriation under s. 20.370 (1) (fu).
(7) Sale of resources. Moneys received from the sale or lease of resources derived from the land in the state natural areas system shall be credited to the appropriation under s. 20.370 (1) (fs).
