Notwithstanding the provisions of section 20.1-02-18, or any other provision of law, the United States may not acquire by any means any land or interests in land for migratory bird reservations, and the governor may not approve the acquisition of any land or interests in land     with moneys from the migratory bird conservation fund until December 31, 1985, or until the date a management plan for such land is approved by both the legislative assembly and the governor, whichever date is first. The management plan must be jointly prepared by the secretary of the interior and the governor and shall address the extent and general locations of all proposed acquisitions with moneys from the migratory bird conservation fund, the management of all such lands whether already acquired or to be acquired, and the relationship of such acquisitions to mitigation acquisitions for federally financed or permitted projects.
