The Gulf Coastal Plains of Texas refers to the development of western part of the coastal plain that starts from the Atlantic Ocean to the Rio Grande. This region is almost a plain area and is cut by the streams and rivers that flows into the Gulf of Mexico. The area of this region is near about 21,000 square mile and is comprised of barrier islands along the coast, marshes that are surrounded by the bays as well as estuaries.
The habitats in the coastal wetland forms the largest plants and animal diversity in the entire aquatic ecosystem of Texas.
This coastal plain of Texas has been expanded over the last sixty million years and is mostly because of the rapid sedimentation that has taken place along these coastal areas due to the actions of the sea waves that carries the particles towards the beach environment.
