D'Arbonne National Wildlife Refuge, Wildlife refuge with bottomland hardwood forest north of West Monroe, Louisiana.

D'Arbonne National Wildlife Refuge lies north of West Monroe in Ouachita and Union Parishes, on both sides of Bayou D'Arbonne near its confluence with the Ouachita River, at the western edge of the Mississippi River alluvial valley. The 13 miles of bayou that bisect it are joined by creeks, sloughs and oxbow lakes among cypress swamps, bottomland hardwood and upland forest.

The refuge was established in 1975 to protect bottomland forests and provide winter grounds for migrating waterfowl. Since then it has served as a critical stopover for birds traveling their annual routes.

The name comes from Bayou D'Arbonne, the 13-mile waterway that bisects the refuge; the bayou is a slow-moving distributary of the Ouachita River, not a coastal inlet. Visitors today fish and boat along it and look for American alligators, Rafinesque's big-eared bats, bald eagles and red-cockaded woodpeckers. No camping is allowed; campers use nearby Lake D'Arbonne State Park.

Seven access points with parking lots sit along Highway 143, making it easy for visitors to start activities like boating, fishing, hiking, or photography. The grounds are open to explore, with the best time for observing birds being from January to May.

The refuge's bottomland hardwood forest acts as an overflow area for the Ouachita River basin, and in wet years high water between January and May can flood up to 87% of the refuge. The same wetland forests filter silt and pollutants from the water and recharge aquifers, reducing flood damage in developed areas downstream.
