Western Gulf Coastal Plain
This EPA Level III ecoregion encompasses all or part of 35 Texas counties. As its name suggests, it is comprised of the coastal plain of Texas, extending along the Gulf Coast south into Mexico and east over portions of the coasts of Louisiana, Mississippi and Alabama. In Texas, it covers approximately the same land area as the Texas Parks & Wildlife Department’s Gulf Marshes and Prairies vegetative region. This collection lists only those taxa found in the Texas portion of the Western Gulf Coastal Plain ecoregion.Printer Friendly: Species List | List with Images | List with QR Tags to Mobile
