4 Piney Woods

5 Climate: Average annual rainfall of 36 to 50 inches is fairly uniformly distributed throughout the year, and humidity and temperatures are typically high. Soil: Generally acidic and mostly pale to dark gray sands or sandy loams Elevation: Ranges from 200 to 500 feet above sea level Geography: Rolling terrain, swampy areas in the south Vegetation: Pine and oak, tall hardwood forests with scattered areas of cropland, planted pastures, native pastures, and rich bottomlands

7 Piney Woods fauna grey squirrel black bear water moccasin cottontail opossum wood pecker whitetail deer raccoon

8 Oak Woods and Prairies

9 Climate: Average annual rainfall averages 28 to 40 inches per year. Soil: Upland soils are light colored, acidic sandy loam or sands. Bottomland soils may be light brown to dark gray and acidic with textures ranging from sandy loams to clays. Elevation: Ranges from 300 to 800 feet above sea level Geography: Gently rolling to hilly terrain Vegetation: Oak savannah, where patches of oak woodland alternate with grassland. year.

12 Blackland Prairies

13 Climate: Average annual rainfall ranges from 28 to 40 inches. May is the peak rainfall month for the northern end of the region; however, the south-central part has a fairly uniform rainfall throughout the year. Soil: Soils are uniformly dark-colored alkaline clays interspersed with some gray acidic sandy loams. Elevation: Ranges from 300 to 800 feet above sea level Geography: Gently rolling to nearly level terrain Vegetation: Food and forage crops

16 Gulf Coast Prairies Marshes

17 Gulf Coast Prairies & Marshes Climate: Annual rainfall varies from 30 to 50 inches per year, high humidity and warm temperatures Soil: Acidic sands and sandy loams, with clays occurring in the river bottoms Elevation: Nearly level, less than 150 feet above sea level, cut by streams and rivers flowing into the Gulf of Mexico Geography: barrier islands along the coast, marshes near bays and estuaries, and prairies Vegetation: Salt grass, tallgrass prairies, live oak woodlands, mesquite and acacias, oaks scattered along the coast, and tall woodlands in the river bottomlands

18 Gulf Coast Prairies & Marshes flora Indian grass big bluestem little bluestemlive oak saltgrass cordgrass

19 Gulf Coast Prairies & Marshes fauna coyote Hog-nosed skunk river otter gulls bottlenose dolphin pelicans roseate spoonbill blue crab lightning whelk

20 Coastal Sand Plains

21 Climate: Average annual rainfall is 24 to 28 inches per year. Soil: Primarily sands Elevation: Fairly level with elevations less than 150 feet above sea level Geography: Windblown sands and unstable dunes with grasslands, stands of oak, and salt marshes Vegetation: Tallgrass prairie with live oak woodlands, mesquite savannah, and salt marshes

22 Coastal Sand Plains flora big bluestem live oak seacoast bluestem crinkleawn toothache tree gulfdune paspalum

23 Coastal Sand Plains fauna coyote collared peccary Texas spiny lizard whitetail deer Texas tortoise jackrabbit

24 South Texas Brush Country

25 Climate: Average annual rainfall of 16 to 35 inches increases from the West to East. Summer temperatures are high, with very high evaporation rates. Soil: Alkaline to slightly acidic clays and clay loams and shallow caliche soils Elevation: Ranges from sea level to 1000 feet Geography: Flat plains to gently rolling terrain Vegetation: Thorny shrubs, trees, and cactus scattered with patches of palms and subtropical woodlands

28 Edwards Plateau

29 Climate: Average annual rainfall ranges from 15 to 34 inches. Soil: Usually shallow with a variety of surface textures, underlain by limestone Elevation: Ranges from slightly less than 100 feet to over 3,000 feet above sea level Geography: Many springs, stony hills, and steep canyons and caves; several river systems dissect the surface, creating a rough and well-drained landscape Vegetation: Grasslands, juniper/oak woodlands, and plateau live oak or mesquite savannah

32 Llano Uplift Enchanted Rock

33 Llano Uplift  Climate: Averages about 24 to 32 inches per year  Soil: Coarse textured sands, produced from weathered granite over thousands of years  Elevation: Ranges from 825 to 2,250 feet above sea level  Geography: Hilly to rolling landscape. With some of the oldest rocks in Texas, the region contains unique minerals, rock formations, and large granite domes.  Vegetation: Oak-hickory or oak-juniper woodlands, mesquite-mixed brush savannah, and grasslands

34 Llano Uplift flora wild rye Texas snowbell boxelder water pennywort Texas wild rice switchgrass

35 Llano Uplift fauna muskrat Guadalupe bass tarantula black-capped vireo blue heron Rio Grande turkey

36 Rolling Plains

37 Climate: Average annual rainfall is 20 to 28 inches; dry summers with high temperatures and high evaporation rates Soil: Varies from coarse sands along outwash terraces by streams to clays and shales Elevation: Ranges from 800 to 3,000 feet above sea level Geography: Gently rolling hills and broad flats are cut by several rivers and their tributaries. Vegetation: Mesquite and shortgrass savannah; various hardwood species along streams, juniper on steep slopes along rivers

40 High Plains

41 Climate: Extended droughts have occurred several times this century. Soil: Surface texture of soils ranges from clays in the North to sands in the South; caliche underlies these surface soils at depths of two to five feet. Elevation: ranges from 3,000 to 4,500 feet above sea level Geography: Relatively level high plateau Vegetation: Mostly irrigated cropland; native vegetation includes mesquite and juniper

45  Climate: 9–15 inches of rain; semi-arid, warm, dry winters  Soil: Generally shallow, saline, and unproductive  Elevation: 2,000 feet to mountain ranges. Highest peak is 8,751 feet above sea level.  Geography: Salt basins, sand hills, rugged plateaus, mountain slopes  Vegetation: Desert grassland, desert scrub, coniferous and mixed hardwood forests at mountain peaks
