The land-based portion of the park, 117 hectares, is characterized by terrace landscapes, flat terrain, and various stands of upland and lowland hardwoods. Bayous and swamps are interspersed throughout the area. Manicured lawns, prairie, and tall-grass areas also exist within the Park. As such, an abundance of flora and fauna resides both on land and in water. Moore Bayou and Post Bayou lie along the north/northwest border and Post Bend Lake, a backwater of the Arkansas River, lies on the north and northeastern border. Both bayous, as well as the backwater, empty into the Arkansas River, which borders the southern edge of the Park. Arkansas Post is the site of over 300 years of European occupation. Consequently, the land-based portion presents a mosaic of different successional stands. Of the twelve general vegetation types delineated, the Superintendent has designated five (excluding mowed areas) as high visitor use areas. They are the oak/pine, oak/hickory, oak/mixed, sweetgum, and tallgrass types.
