Dynamics: No Data Available
Environmental Description: This community occurs in shallow depressions on sandstone ridgetops or saddles. These depressions are flooded continuously for a relatively short period of time in the late winter and early spring, and probably also refill after heavy rain events in other seasons. The ponding prevents most herbs from growing.
Geographic Range: This community is known only from the Cumberland Plateau of Alabama, but is probably more widespread.
