St. Francis Sunken Lands Natural Area is located in the Mississippi Alluvial Plain on the east side of the St. Francis River within an area of bottomland forest known as the St. Francis Sunken Lands. It includes a portion of the largest known Arkansas population of the federally endangered shrub pondberry. The area is characterized by varied microtopography consisting of a series of shallow, north-south trending channels which are separated by low, sandy ridges of relative uplands (1 to 3 feet high). The area is seasonally inundated by flood waters in winter and spring, but the varied microtopography provides a hydrologic gradient along which a rich diversity of plant species is found. The natural area lies adjacent to St. Francis Sunken Lands Wildlife Management Area.
