16 U.S.C. § 460nnn–24 — Land acquisition authority

(a) Acquisition. Besides the land acquisitions required under part F, the Secretary can acquire other non-federal land and land interests located inside the Cooperative Management and Protection Area or the Wilderness Area. But this can only happen through a voluntary exchange, a donation, or a purchase from a willing seller. (b) Treatment of acquired lands. Land acquired this way, or through part F, automatically joins whichever zone it's located in and follows that zone's rules. If it's inside the Cooperative Management and Protection Area's boundaries, it (A) becomes part of that area and (B) is managed under the laws that apply there. If it's inside the Wilderness Area's boundaries instead, it (A) becomes part of the Wilderness Area and (B) is managed under part B and the other laws that apply to wilderness. If it's inside a wilderness study area's boundaries, it (A) becomes part of that study area and (B) is managed under the laws that apply to wilderness study areas. (c) Appraisal. When the Secretary appraises non-federal land, development rights, or conservation easements for possible purchase under this section or section 460nnn–42, the Secretary must ignore any drop in value caused by the Cooperative Management and Protection Area or Wilderness Area being designated in the first place.
