La. Stat. tit. 56 § 782
When a tract of land owned by the state has been selected for wildlife refuge, wildlife management area, public hunting ground, upland game preserves, or wildlife sanctuaries by the commission, notice containing a description by section, township, and range of the lands selected shall be given by the commission to the state land office, or other proper departments, of the selection of the lands for that purpose. The commission shall publish for a period of not less than thirty days notice of intention to dedicate the described lands for a wildlife refuge, wildlife management area, a public hunting ground, upland game preserves, or wildlife sanctuaries in a newspaper published or having a circulation within the parish or parishes in which the area is situated. Thereupon, the lands become perpetually dedicated to the purpose of maintaining a wildlife refuge, wildlife management area, a public hunting ground, upland game preserves, or wildlife sanctuaries. Thereafter no use shall be made of the lands inconsistent with or harmful to the purpose of providing a wildlife refuge, wildlife management area, a public hunting ground, upland game preserves, or wildlife sanctuaries.
