Transcript of Blackland Prairies



Llano Uplift
Eastern Region of Texas- apart of a larger forest that extends into Louisiana, Arkansas, and Oklahoma.
Humid Subtropical Climate Zone
During the winter it gets as cold as 30 degrees. In the summer it gets as hot as high 90s.
One of the critically endangered ecoregions of the US.
Biotic Creatures
There are many different mammals: Eastern Cottontail rabbits, Eastern Gray Squirrels, Virginia Opossums, Nine-banded Armadillos, White-tailed deer, North American Cougars, Gray Foxes, Bobcats, Ring-tailed Cats, Rafinesque's Big-eared Bats, and Seminole Bats
Reptiles include: Western cottonmouths, Prairie Kingsnakes, Slender Glass Lizards, Squirrel Treefrogs
Birds include: Sandhill Cranes, Black and Turkey Vultures, Northern Mockingbirds, and the vulnerable Red-cockaded Woodpecker
Fish include: Catfish, Crayfish, and many others
There is a rich variety of trees, shrubs, woody vines.
Lots of hardwood trees are found in this region.

Abiotic Features
Receives more than 60 inches of rain each year.
It is the wettest region of Texas
Occupied by deep, fertile, sandy loam soils which are generally slightly acidic
Blackland Prairies
Some of the present native species consist of small game animals, songbirds, waterfowls, shore birds, pocket gophers, reptiles, and a limited population of white-tailed deer.
Food grown throughout the region: Cotton, corn, milo, and wheat
Plants grown on steep areas: eastern red cedar, Ashe juniper, cedar elm, Texas persimmon, elbowbush, deciduous holly, live oak
Woody vegetation including mesquite, hackberry, elm, osage orange, and other woody species grow along fence lines and field borders providing habitat for wildlife
There is a high level of animal diversity due to the variety of
in Blackland Prairies.
Precipitation- about 30-45 in. or 750 to 1,150 mm mainly from April to May
Summer droughts are increasingly apparent, due to the extreme weather conditions induced by global warming trends.
During the winter it varies from mid 40’s to 50’s Fahrenheit. And in the summer it varies from low to upper 90’s Fahrenheit.
Blackland Prairie’s soil is a mixture that is unique from other prairies.The fertile dark clay soils of the Blackland Prairies are some of the richest soils in the world.

The soil, which is categorized as deep calcareous deposits, is ideally suited to crop agriculture. This has led to most of the Blackland Prairie ecosystem being converted to crop production, leaving less than 1% remaining.

Scientists believe the richness of the prairie soils is derived from the abundant invertebrate
fungal flora
found in the soils themselves.
How does the Pineywoods help out the state?
The Pineywoods region is important because of their timber and cattle industries.
Issues in the Pineywoods...
Industrial pollution and high mercury levels caused fish consumption advisories in two reservoirs.
24 to 32 inches of rain per year. Peaking in May or June.
Soils are coarse textured sands, produced from weathered granite.
Lots and lots of rocks!!!
Some of the oldest rocks are found here.
Biotic Creatures
Oak-hickory, Oak-juniper woodlands, mesquite-mixed brush savannah, and grasslands.
Mammals include: Armadillos, Badgers, Bats, Coyote, Deer, Squirrel, Opossum, Rabbits, Racoons,
Reptiles include: Rattlesnakes, lizards
Birds include: Owls, Hawks, Buzzards
Llano Uplift Industries!
The Llano Uplift region is the heart of the wine industry.
Provides rocks (mostly granite) for building things.
Agriculture is a big industry.
Issues in the Llano Uplift...
Overgrazing by domestic livestock
Overstocking rangelands with livestock
Central Texas- Eastern region of Edwards Plateau and Northern region of Texas Hill country.
Roughly circular geologic dome of Precambrian rock, primarilary granite
Norther part of Texas Hill Country
Abiotic Features
Gulf Coast Prairies and Marshes
Abiotic Factors
Regional Average Rainfall - Mid-North: 40-60 in./yr
The growing season is usually more than 300 days, with high humidity and warm temperatures.
Surficial and windblown sands and dunes characterize this region’s soils.
Most of the lower lands are in large cattle ranches.
Uplands in the Gulf Prairies are ranching interspersed with farming.
Habitat Issues
•Gulf coastal marshes have been adversely affected by the construction of levees on the Mississippi River, the Gulf Intracoastal Waterway and numerous navigation canals.
•In the past 50 years, marsh has been lost at a peak rate of about 40 square miles annually.
•Since 2005, four major hurricanes and the Deepwater Horizon oil spill have accelerated marsh loss and degradation along the Gulf Coast.
•Water availability limitations, particularly in Texas are threatening rice agriculture and other managed wetlands along the coast.
•Recent declines in rice acreage in the region contribute to the loss of feeding and resting habitat.
The impacts of a changing climate could have significant effects on Texas's natural systems and the goods and services they provide.

General info
The Gulf Prairies and Marshes Area occupies approximately 9,500,000 acres along the coast of Texas. The Gulf Prairies and Marshes region is a nearly level, slowly drained plain less than 150 feet in elevation, dissected by streams and rivers flowing into the Gulf of Mexico. The region includes the barrier islands lining the coast which protect the shoreline from the constant buffeting of harsher ocean waves, and the highly productive estuaries and marshes that support a thriving fishing economy.
Biotic Factors
Texas madrone, Grasses, Tallgrass prairies, L Sugarberry, Green ash, Sweetgum, Water oak, Willow oak, Southern live oak American elm, Holly, Yaupon, Red mulberry, Wax myrtle, Cherry-laurel, Sweet bay, Red chokecherry, Short-leaf pine
Muskrat, Coyote, Marsh rice rat, Mink, River otter, Bottlenose dolphin, Alligator, Diamond back terrapin, Bull frog, Roseate spoonbill, Black skimmer, Gulls, Terns, Pelicans, Spotted sea trout, Red drum, Southern flounder, Striped mullet, Sheepshead, Shrimp, Blue crab, Snappers, Spadefish, Groupers
Something Unique to the Area
In the region of the western Gulf of Mexico, Texas has a subtropical and mostly semi-arid climate.
Persistent southeast winds off the Gulf dry out the landscape in this coastal region.

Canyon of the Eagles
Canyon of the Eagles is an ideal vacation for adventurers and for those who just want to get away. Just one hour northwest of Austin, this secluded, 940-acre Hill Country resort and nature park features beautiful nature trails and the pristine Lake Buchanan. This is the ideal getaway for fishing and outdoor adventure such as canoeing and kayaking. Or, take a Texas River Cruise and enjoy the beautiful natural surroundings of the area. Onsite you'll find their spacious amphitheater, an outdoor pool, and a variety of entertainment such as storytelling, a cowboy poet, and live music. For Hill Country corporate retreats, the Overlook Restaurant features full-service dining.
Burnet, Texas
Silver Spur Ranch
Bandera, Texas
Experience the charm and tranquility of life as a Western cowboy at the Silver Spur Ranch. Throw on those blue jeans and saddle up for the two hours of guided horseback riding on trail each day. You can also take your horse for a variety of activities at the arena! After riding, relax inside the ranch's 14,000-square-foot Western lodge. Cuddle up next to the fireplace in its spacious lounge, play a game of pool, or stay outdoors for a game of volleyball. The kids will love the playground and the swimming pool, the area's largest; and after a hearty meal in the ranch's 100-seat dining room, the whole family can head to the lodge's vast front porch to watch a serene sunset.
