It is one of only six National Forests that are contained entirely within a single county and the only bottomland hardwood forest in the National Forest system. The Green Ash-Overcup Oak-Sweetgum Research Natural Areas within the Delta National Forest are a rare example of pristine bottomland hardwood forests. They were declared National Natural Landmarks in May 1976.
