The Coastal Tallgrass Prairie

Attwater's prairie chickens will remain in pens such as this one to get acclimated to their new surroundings before they are released into the wild. The pen shown here stands amid the Goliad Prairie in South Texas, a 60,000-acre expanse of unplowed native prairie on private ranchland. © Earl Nottingham/Texas Parks and Wildlife Department

The tallgrass prairie is a relatively treeless native grassland containing key grass species and a diversity of forbs, or broadleaf wildflowers. Texas and Louisiana coastal prairie is similar to the greater tallgrass prairie of the eastern Great Plains, containing most of same key species. It is somewhat more diverse, however, and includes some subtropical grass species also found in Latin America.
The virgin, native Goliad and Refugio prairies have not been plowed but they have been grazed – by native grazers, including pronghorn, bison – and by cattle. It is believed that Spanish cattle may have grazed on the coastal prairie as early as the 1500s. Managed grazing is now used to help maintain prairie health.
Wildfire was an important part of how prairies originally developed, with periodic lightning-caused fires keeping grasslands open and free from woody species. Native Americans started fires on the prairie, most likely to enhance hunting and grazing. Today, prescribed burning is a key tool for prairie conservation.
Coastal prairies also support key animal species. Coastal grasslands are especially important for wintering birds, with almost all grassland bird species now in decline.
