General Wildlife


Wildlife species on the refuge are those indigenous to the marshes of coastal Louisiana. A large population of alligators and furbearers such as nutria and racoon call the refuge home.

Lacassine Refuge provides suitable habitat for armadillos, rabbits, squirrels, nutria, mink, muskrats, skunks, opossums, otters, racoons, coyotes, and whitetail deer. It is estimated that the deer population on the refuge is approximately 300 individuals. Approximately 50 percent of the refuge, or 16,000 acres, is suitable deer habitat. The Louisiana Department of Wildlife and Fisheries estimates that excellent freshwater marsh habitat can support a potential density of one deer per 30 acres. On Lacassine Refuge, whitetail deer are concentrated on the spoil banks and agricultural fields found throughout the refuge.
Amphibians and Reptiles  

As a freshwater marsh, Lacassine Refuge is a haven for reptiles and amphibians. Despite the dominance of these creatures in this landscape, little is known about their populations on the refuge. The American alligator is the only member of this group that is managed. Lacassine Bayou should support a different assemblage of species than those found in Lacassine Pool but in depth surveys have not been conducted. Alligator snapping turtles have been recorded om Lacassine Bayou, which have been identified as a species of concern.

Aquatic Species

Fish species present include catfish, bowfin, bass, bream, crappie, and gar. Fish populations of Lacassine Refuge have periodically suffered from the negative effects of drought. In the early 1990's levees were upgraded so that the level of the Lacassine Pool could be raised from 4 to 5 feet mean sea level. The deeper water areas provide a more stable water quality that supports a better fish habitat.
