Pines dominate this area, largely shortleaf pine in the north, including the Ouachita Mountains, and longleaf pine in the south. This westernmost part of the eastern United States forest also includes hardwood dominated bottomlands along the Arkansas River and other drainages. Red-cockaded Woodpecker is the highest priority bird in pine habitat, which is also inhabited by Bachman's Sparrow and Brown-headed Nuthatch. Conversion of the native pine forests to industrial loblolly plantations provides some bird habitat, but is less useful for the highest priority species. The river and stream bottoms provide habitat used by Swainson's Warbler and large numbers of nesting herons and egrets. Bottomland hardwoods and associated wetlands support substantial wintering populations of a number of waterfowl species, principally Mallards, and breeding and wintering Wood Ducks, and are a primary migration corridor for significant numbers of other dabbling ducks. The principal threats to bottomland hardwood wetlands in the region are from reservoirs and timber harvest and subsequent conversion to pine plantation, pasture, or other land uses.
