Lacassine NWR, in Cameron and Evangeline Parishes in southwestern Louisiana, was established on 12/30/37 by Executive Order No. 7780 as “a refuge and breeding ground for migratory birds and other wildlife.” The refuge is nearly 35,000 acres in size, including 653 acres leased from the Cameron Parish School Board. The vegetation types occurring on the refuge are primarily water tolerant grasses, sedges, and shrubs. Vegetation in the undeveloped marshes is dominated by bulltongue and maidencane. The habitat is divided into 16,500 acres of natural, freshwater marsh and open water, 16,000 acres of managed, freshwater marsh (Lacassine Pool), 2,200 acres of rice, wheat, soybean, and natural moist soil fields, 350 acres of flooded gum and cypress trees, and 350 acres of restored tallgrass prairie. Wildlife species found on the refuge are those indigenous to the marshes of coastal Louisiana.
