Researchers with the Memphis Zoo have released 50 endangered Louisiana pine snakes into a national forest in an attempt to revive their population. On April 22, the Memphis Zoo’s research team and partners from the U.S. Fish and Wildlife Service, the U.S. Forest Service, and zoos in Fort Worth, Texas, and Alexandria, Louisiana, released the young pine snakes into their natural habitat at Kisatchie National Forest. The snakes were safely placed into stump holes and tunnels where pocket gophers live in the Louisiana forest. The snakes’ main prey is pocket gophers. Researchers hope that the snakes will breed effectively.
