The Secretary, in the exercise of his exchange authority, may accept title to any non-Federal property in townships 65 and 66 south, ranges 28, 29, and 30 east, Monroe County, Florida, and in exchange therefor convey to the grantor of such property any federally owned property in the State of Florida under his jurisdiction which he classifies as suitable for exchange or other disposal.

The properties so acquired shall constitute the National Key Deer Refuge, and shall be administered by the Secretary of the Interior in accordance with the laws and regulations relating to the national wildlife refuges, including, but not limited to, sections
