The westward expansion of human population in Texas has been especially pronounced along Highway Edwards Plateau may favorably impact the effect of woody plant removal on water yield (Wilcox, 2002) Edwards Plateau landowners (Fulbright, 1997; Rollins et al., 1988). The escarpment and faults also plays a role with regional water resources. Before the area became settled, grassland reigned across the plateau. The semiarid Stockton Pla- teau is an extension of the area west of the Pecos River. water and the impact of woody plant encroachment of invasive species on water resources. The behavioral evolution of humans to harness and apply fire has shaped the structure and function of grasslands on Earth for tens of thousands of years, but many modern societies have evolved past this legacy (Pyne 2001, 2007).This change in human behavior, combined with other sources of anthropogenic change such as climate change, the Diagram illustrating the interaction between biodiversity and geographic scale ..4 Figure 3. the Edwards Plateau (area 11).

Pearce began excavating sites in the Austin area around 1919. A map showing the counties is provided by Texas Parks and Wildlife Department for the Edwards Plateau Ecoregion. Texas comprises the eastern portion of the Southwest region, where the convergence of climatological and geopolitical forces has the potential to put extreme stress on water resources. Many Texas landowners and cities depend on this high-quality, usually abundant source of groundwater. Another important area for wildlife is Fort Hood military base.[8]. Frequent fires were part of the natural cycle of birth and rebirth, helping to curtail the spreading of shrubs and cedar. Cretaceous limestones and dolomites characterize most of the Edwards Plateau and produce a karst topography with . San Angelo, Austin, San Antonio and Del Rio roughly outline the area. The Texas Rangers and U.S. military patrols, which set up a frontier line of forts to protect the encroaching settlers, drove out or relocated all the Texas-native tribes by the end of the 19th century. beginning controlled
Edwards Plateau ecology: references & links - University of Texas at Austin Overgrazing of cattle, sheep, and goats also led to the erosion of prairie land and the encroachment of shrubby species like mesquite and ashe juniper. Possible factors include changes in habitat, and increased human population. Low reproduction rates and survival of white-tailed deer and pronghorn fawns often results in downward population trends.

After 1.6 ka, from the Tang Dynasty onwards, human settlement and grazing activity intensified on the northeastern Qinghai-Tibetan Plateau, and this is in accord with the observed high percentages of Stellera in the pollen record. Spatial analysis also made possible the prioritization of ecological sub-regions of the Edwards Plateau for conservation or restoration. Priority Places. It is timbered, but grasses are practically absent on the rougher portions of the granitic central section. On the east and south, the Balcones Escarpment forms a distinct boundary to the Edwards Plateau, but on the west the pla- teau blends into other regions.
