All exchanges pursuant to this subchapter shall be made in a manner consistent with applicable provisions of law, including this subchapter, and unless otherwise specified in this subchapter shall be on the basis of equal value; either party to an exchange may pay or accept cash in order to equalize the value of the property exchange, except that if the parties agree to an exchange and the Secretary determines it is in the public interest, such exchange may be made for other than equal value.

For purposes of this subchapter, the term “public lands” shall have the same meaning as such term has when used in the Federal Land Policy and Management Act of 1976 [43 U.S.C. 1701 et seq.].

Except as otherwise provided in section 460uu–45 of this title, any lands or interests therein within the boundaries of the monument or conservation area which after December 31, 1987, may be acquired by the United States shall be incorporated into the monument or conservation area, as the case may be, and managed accordingly, and all provisions of this subchapter and other laws applicable to the monument or the conservation area, as the case may be, shall apply to such incorporated lands.

The acreages cited in this subchapter are approximate, and in the event of discrepancies between cited acreages and the lands depicted on referenced maps, the maps shall control.

The Secretary is authorized to accept any lands contiguous to the boundaries of the Pecos National Monument (as such boundaries were established on December 31, 1987) which may be proposed for donation to the United States. If acceptance of such lands proposed for donation would be in furtherance of the purposes for which the Pecos National Monument was established, the Secretary shall accept such lands, and upon such acceptance such lands shall be incorporated into such monument and managed accordingly.
