Texas
Ecoregions
1. Piney Woods
Location East Texas
Precipitation Regional Average Rainfall: 40-52 in./yr
Temperature
Characteristics *Thick forest of pines, bottomlands (swampy), hardwood trees*”Big Thicket” southern most regionHigh HumidityTimber and cattle productionSwamps are common
2. Oak Wood & Prairies
Location Extends northward into the Great Plains or eastward into the forests..sometimes called Cross-Timbers
Precipitation 28-40 inches
Temperature
Characteristics Gently rolling to hilly and elevations range from 300 to 800 feet above sea levelOak savannah, patches of oak woodland are interspersed with grassland Cattle ranching is a mojor ag industry
3. Blackland Prairie
Location Between Piney woods and Plains
Precipitation 28 to 40 inches
Temperature
Characteristics Rich, fertile soilsGently rolling landscape to nearly levelCrop ProductionCattle Ranching
4. Gulf Coast Prairies & Marshes
Location Gulf Coast—Gulf of Mexico
Precipitation 40-60 inches
Temperature
Characteristics Includes marshes, barrier islands, estuaries, and baysSlowly drained plains, less than 150 feet in elevationHigh humidity, warm temperaturesNative habitat has been lost to agriculture & urbanization but still provides habitat for migratory birds and spawning areas fro fish and shrimp
5. Coastal Sand Plains
Location Extends from Gulf Coast Plains to South Texas Brush County
Precipitation 24-28 inches
Temperature
Characteristics Most of the region is grazed by cattleTall grass prairie with live oak woodlands, mesquite savannah and salt marshes
6. South Texas Brush Country
Location Rio Grande Valley area
Precipitation 20-32 inches
Temperature
Characteristics Thorny bushes, mesquite acacia, prickly pear with areas of grasslandRich in wildlife and a haven for many rare species of plants and animalsLivestock grazing and crop production are the principal agland uses
7. Edwards Plateau
Location Central Texas-Hill Country
Precipitation 15-34 inches
Temperature
Characteristics Land of springs, stony hills and steep canyonsHome of rare plants and animalsThe limestone is honeycombed with thousands of cavesRanching is the primary ag industrySurrounds the Llano Uplift
8. Llano Uplift
Location Center of Edwards Plateau
Precipitation 24-32 inches
Temperature
Characteristics Central mineral regionHome to some of the oldest rocks in TexasEnchanted RockOak-hickory or oak-juniper woodlands, mesquite-mixed brush savannah and grasslandsRanching
9.Rolling Plains
Location Middle North, Between High Plains, Edwards Plateau and Blackland Prairie
Precipitation 20-28 inches
Temperature
Characteristics Mesquite-shortgrass SavannahSteep slopes, cliffs, and canyons comprise the Escarpment Breaks area-which is the transition area between High Plains and Rolling PlainsDrop and livestock production
10. High Plains
Location Most of the Panhandle
Precipitation 15-22 inches
Temperature
Characteristics Relatively level high plateauElevations are from 3000 to 4500 feetExtended droughts are normal Shortgrass Prairie, Juniper and Shinnery oak and Sand Sage are commonBuffalo and Pronghorn Antelope once populated the area, today mostly irrigated cropland and native vegetation
11. Trans Pecos
Location Extreme Western part of the state eastward of the Pecos River
Precipitation Less than 12 inches
Temperature
Characteristics Many vegetations types exist due to the diversity of soildand elevationsCreosote-tarbruch desert scrub, desert grassland, yucca and juniper savannahs, montane forests of pine and oakThere are various subregions that reflect the diversity of the Trans PecosRanching in a primary industry
12. Marine Evironment
Location Gulf Coast of Mexico
Precipitation Same as Gulf Coast Ecoregion
Temperature Same as Gulf Coast Ecoregion
Characteristics Salt water, beach, bays, estuaries
