Within the conservation area, and subject to the provisions of this section, the Secretary is authorized to acquire lands, interests in lands, and associated water rights, by donation, purchase, exchange for Federal lands outside the conservation area, or transfer from another Federal agency with the concurrence of the head of the appropriate agency thereof.

No privately owned lands, interests in lands, or associated water rights, may be acquired without the consent of the owner thereof unless the Secretary determines that, in his judgment, the property is subject to, or threatened with, uses which are having, or would have, an adverse impact on the resource values for which the conservation area was established.

Any lands, waters, or interests therein within the boundaries of the conservation area which after November 16, 1990, may be acquired by the United States shall be incorporated into the conservation area and be managed accordingly, and all provisions of this subchapter and other laws applicable to conservation areas shall apply to such incorporated lands.
