Little River National Wildlife Refuge in McCurtain County, southeastern Oklahoma, protects about 15,000 acres of forests and wetlands and preserves much of the region’s remaining bottomland hardwood habitat. Its low, wet landscape is shaped by oak and hickory forest interrupted by oxbows and sloughs. The refuge supports a varied mix of trees, including willow oak, sweetgum, cypress, white oak, loblolly pine, hickory, and walnut, making it an important example of this diminishing natural environment.
