Kisatchie National Forest, the only National forest in Louisiana, United States, is located in the forested piney hills and hardwood bottoms of seven central and northern parishes. It is part of the Cenozoic uplands and has large areas of longleaf pine forests. It is one of the largest pieces of natural landscape in Louisiana, with some 604,000 acres of public land, more than half of which is vital longleaf pine and flatwoods vegetation. These support many rare plant and animal species.
