Range Description

Arkansas Oak (Quercus arkansana)is endemic to the southeastern United States, mainly along the Gulf Coastal Plain where it occurs sporadically in scattered sites. This species can be found from the states of Georgia into eastern Texas, but its range is divided by the Mississippi River Delta, from which it is believed absent. Given this wide span, this species' estimated extent of occurrence (EOO) is roughly 345,000 km2; however, because of its small, scattered occurrences, the area of occupancy (AOO) of Arkansas Oak is restricted, estimated to be about 1,000km2 (based on extensive research of known occurrences, using over 360 coordinate data points).One occurrence has been reported from eastern Georgia, which represents the far eastern edge of the range and the only known report of this species from the Atlantic Coastal Plain.Arkansas Oak is believed to be a relictual species, with a historically wider range that is now restricted to isolated subpopulations, most often localized around mesic sandhills, ravine slopes and stream heads.
