The Crosstimbers is an 11.5-million acre belt of landscape
the Oklahoma border southward 160 miles across the upper Trinity and
featuring alternating swaths of post oak, hackberry, ashe juniper and
elm woodlands and tall-grass prairies
bluestems, gramas, and Indiangrass, broken by bottomland forests of
cottonwood, sycamore and bur oak.
Industry in this area includes cotton, sorghum, livestock, oil and gas
extraction, lignite mining, and diversified commerce. The major towns
the Crosstimbers include Athens, Bryan-College Station, Fort Worth, Glen
Rose, Mineral Wells, Seguin, Stephenville, and Sulphur Springs.
Significant protected areas in the Crosstimbers include the Aquilla
Wildlife Management Area (6100 acres), Hagerman National Wildlife Refuge
(11,320 acres), Lake Mineral Wells State Park (2843 acres), and the Ray
Roberts Lake State Park and Wildlife Management Area (21,020 acres).
Conservation challenges for the region include air quality problems,
from ozone level exceedances in the Dallas-Fort Worth Metroplex, to
emissions from cement kilns in the Midlothian area.
Sprawl in the Metroplex is a problem as well, with a 1970-90 consumption
372 square miles of open land, giving it a rank of 7th among all major
cities. The region also faces the need to protect some of the last
of tallgrass prairie in Texas, less than 1% of which is left from
pre-Western settlement times. The region also has the opportunity to
conserve some of the oldest first-growth forests in the state: the post
In addition, water use in this region is a challenge: the average Fort
Worth resident uses 214 gallons per day, together with Dallas, the
in the state, and well above residents of El Paso (159 gallons per day)
San Antonio (147 gallons per day). There are concerns that reservoirs,
as the 70,000-acre Marvin Nichols reservoir on the Sulphur River, may
built to slake this thirst before more cost-effective and
friendly conservation can take hold.
