The trees that are native to North Texas are naturally shorter. For example, the Texas red oak, which is native to North Texas, grows to about 40 feet while the Shumard red oak, native to East Texas, grows to more than feet. Most trees cannot grow taller than to feet because the tree must be able to defy gravity to transport water from the roots to the top.
A tree with a inch diameter requires 1, square feet of open soil space, he said. Trees in Dallas are planted in small spaces that are often surrounded by concrete. For example, much of North Texas was native prairie that had few trees except around water sources, Houser said.
Courtney Blevins, a Fort Worth regional forester with Texas Forest Service said climate is one of the most influential factors in the development of North Texas trees. Southeast Texas can get more than 60 inches of rain a year, while El Paso gets less than Some places in Texas have more ideal soil types or receive more rainfall, such as along the coast, which allows trees to grow taller in less time.

The soils of the region are generally acidic and mostly pale to dark gray sands or sandy loams. Longleaf pine forests once dominated the southeastern part of the Pineywoods. A few pockets of longleaf pine may still be seen today.
Mixed pine-oak forests occur to the west and north of the longleaf pine area. Dominant trees include loblolly pine, blackjack oak, and post oak.
Hardwood forests of sweetgum, magnolia, tupelo, elm and ash occur in the lowlands. Swamps are common and are outstanding in the southern part of the pine-oak forest.
Regional Average Rainfall: in. The average annual rainfall is fairly uniformly distributed throughout the year, and humidity and temperatures are typically high. Elevations range from to a little over feet above sea level.
Dept of Commerce. The counties contain Texas' Other Tree Regions. Big Tree Registry. Nearly all Texas timberland acreage remained stable between and This is a result of a balance between new timberland acres coming from agricultural lands, which are either intentionally planted with trees or have naturally reverted to forest, and previous forested land that is converted to other uses, such as commercial or residential areas.
Ninety-two percent of East Texas timberland is owned by approximately , private individuals, families, partnerships, corporations, forest-products companies, and timber investment groups. The remaining 8 percent is owned by federal, state, and local governments. The following table shows acreage of timberland by ownership:.
Ownership Class Thous. East Texas has undergone major shifts in private ownership during the past decade, primarily a transfer of land from forest industry owners to non-industrial private owners. Information from several sources, such as the FIA, National Woodland Owner Survey, and timberland transaction records, suggests that the forest industry now accounts for no more than 50 thousand acres.
Non-industrial private corporations, which include timber investment corporations, account for 3. Six major forest types are found in the East Texas Piney Woods. Two pine-forest types are most common.
The loblolly-shortleaf and longleaf-slash forest types are dominated by the four species of southern yellow pine. In these forests, the various pine trees make up at least 50 percent of the trees. Oak-hickory is the second most common forest type. These are upland hardwood forests in which oaks or hickories make up at least 50 percent of the trees and pine species are less than 25 percent. Oak-pine is a mixed-forest type in which more than 50 percent of the trees are hardwoods, but pines make up 25 percent to 49 percent of the trees.
Two forest types, oak-gum-cypress and elm-ash-cottonwood, are bottomland types that are commonly found along creeks, river bottoms, swamps, and other wet areas. The oak-gum-cypress forests are typically made up of many species including blackgum, sweetgum, oaks, and southern cypress. The elm-ash-cottonwood bottomland forests are dominated by those trees but also contain many other species, such as willow, sycamore, and maple. Other forest types found in East Texas include small acreages of mesquite, exotic hardwoods, red cedar, and unproductive lands that are considered forested but do not meet stocking requirements.
The following table shows the breakdown in acreage by forest type:. Forest Type Group Thous. Southern Pine: Loblolly-shortleaf Southern pine plantations, established by tree planting and usually managed intensively to maximize timber production, are an important source of wood fiber.
Texas forests include 2. Genetically superior tree seedlings are usually planted to improve survival and growth. Texas timberland contains about One billion cubic feet of growing stock produces roughly enough lumber to build a 2,square-foot home for one out of every three Texans. The inventory of softwood increased slightly from 9. The hardwood inventory decreased slightly from 8. There are an estimated 7. This includes 2.
