Felsenthal National Wildlife Refuge is a 76,000-acre protected wetlands landscape in south-central Arkansas at the confluence of the Saline and Ouachita rivers. Established in 1975 as mitigation for the U.S. Army Corps of Engineers’ Ouachita-Black Rivers Navigation Project and the construction of Felsenthal Lock and Dam, it is part of a three-refuge administrative complex. The refuge also protects more than 200 Native American archaeological sites, mainly of Caddo origin. Its rivers, creeks, sloughs, lakes, bottomland hardwood forest, and upland forest create diverse habitat for more than 1,150 documented species, including Arkansas’s only national wildlife refuge population of the federally protected red-cockaded woodpecker.
