Endangered and Threatened Wildlife and Plants; Establishment of a Nonessential Experimental Population of Endangered Whooping Cranes in Southwestern Louisiana

We, the U.S. Fish and Wildlife Service (Service), will reintroduce whooping cranes (Grus americana) into historic habitat in southwestern Louisiana with the intent to establish a nonmigratory flock. We are designating this reintroduced population as a nonessential experimental population (NEP) under section 10(j) of the Endangered Species Act of 1973 (ESA), as amended. The geographic boundary of the NEP includes the entire State of Louisiana. The objectives of the reintroduction are: to advance recovery of the endangered whooping crane; to implement a primary recovery action; to further assess the suitability of Louisiana as whooping crane habitat; and to evaluate the merit of releasing captive-reared whooping cranes, conditioned for wild release, as a technique for establishing a self- sustaining, nonmigratory population. The only natural wild population of whooping cranes remains vulnerable to extirpation through a natural catastrophe or contaminant spill, due primarily to its limited wintering distribution along the Texas gulf coast. If successful, this action will result in the establishment of an additional self- sustaining population, and contribute toward the recovery of the
