Common (Translated Scientific) Name: Eastern Gamagrass - Tall Dropseed Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is found in the Blackland and Fayette prairie regions of Texas. It is dominated by Tripsacum dactyloides. Similar communities may exist as small patches in Oklahoma. Once extensive from south-central Texas to the Red River, this community now occurs as isolated remnants, often surrounded by cropland. Eastern gamagrass-dominated areas are the most endangered grasslands in Texas.
