The Gulf Coast is a nearly level, slowly-drained plain. It is dissected by streams and rivers flowing into the Gulf of Mexico. Here you can find: barrier islands along the coast; salt grass marshes surrounding its bays and estuaries; a few remaining patches of tallgrass prairies; oak mottes scattered along the coast; and tall woodlands in the river bottomlands. Soils are acidic sands and sandy loams, with clay soils occurring primarily in the river bottoms.
