Site Description
The Lyndon B. Johnson National grasslands (CLBJ) is a core terrestrial within NEON's Domain 7: Southern Plains. CLBJ is located in the Great Plains region of north-central Texas, about an hour drive from the Dallas-Fort Worth metroplex. LBJ occupies approximately 20,000+ acres of public lands managed by the U.S. Forest Service. The grasslands are home to Black Creek Lake, which hosts an established recreation site consisting of seven picnic units, seven walk-in camp units, one improved boat ramp and an accessible fishing bridge. There are nearly 75 miles of established trails on site great for hiking, mountain biking, horseback riding, photography, and wildlife viewing. Remote sensing surveys of this field site collect lidar, ...

Geology
Antlers Sand Unit, sand, mud, and clay. Early Cretaceous.
Vegetation
Savanna vegatation is fairly characteristic of LBJ with woody species occupying about 30 to 40 percent of the area. In general, the composition of woody vegeation is approximately 63 percent post oak, 29 percent blackjack oak, and 8 percent consisting of a mix of toher species such as cedar, elm, and hackberry. Little bluestem is the primary grass for the area, co-associated with big bluestem and indiangrass.
Soils
The dominant soil type is clay-rich Alfisols.
