Dynamics:  Flooding, with associated anaerobic soil conditions and nutrient pulses, is the primary natural disturbance in this community. Due to moist-wet conditions, this community seldom burns. Although primarily experiencing gap phase regeneration, this forest can undergo occasional periods of prolonged flooding causing widespread mortality. Although this community can be early successional, occurring on river fronts and other recently disturbed areas, this is a generally long-lived type (Eyre 1980).

Environmental Description:  No Data Available

Geographic Range: As currently described, this association occurs in the Upper West Gulf Coastal Plain and Crosstimbers and Southern Tallgrass Prairie ecoregions in Oklahoma, Arkansas and possibly Louisiana.

Nations: US

States/Provinces:  AR, LA?, OK, TX?
