These hills and surrounding valleys of the Hill Country are a direct result of limestone washing away. The landscape of the plateau is mostly savanna scattered with trees. At the same time, ecosystems are stressed by human impacts, such as the conversion of land for urban or agricultural use, which can exacerbate the effects of climate change. Protective canyons, especially on the eastern and southern portions of the plateau, provide for a great diversity of other hardwood species such as Texas madrone, escarpment black cherry, Texas mountain-laurel, Mexican plum, Carolina basswood, lacey oak, and bigtooth maple. Figure 3. During the Cretaceous Period, deposits of sandstone, limestone, shales, and dolomites accumulated on the ancient oceans floor. The inner portion is underlain by granitic and metamorphosed pre-Cambrian rocks; the outer portion, rimming the granitic outcrops, is underlain by Paleozoic sedimentaries that dip beneath the surrounding and geologically younger Comanchean limestones. By browsing on softer grasses and plants, harder to eat forage plants, like cedar, took over an area that was originally a grassland. Less visible was the effect these settlers had on the landscape.

Based on our analysis of 14 year (i.e., 2002-2015) Stage IV precipitation data, the impact of the Edwards Plateau on the spatial distribution of precipitation is most prominent in August (Figure 1b), probably due to strong radiative heating and fewer disturbances by strong synoptic scale transient .

The Edwards Plateau is a region of west-central Texas which is bounded by the Balcones Fault to the south and east, the Llano Uplift and the Llano Estacado to the north, and the Pecos River and Chihuahuan Desert to the west. The settlers lived on farms and ranches, and their animals changed the native plants in the area. Although a plateau, much of region is dissected with steep canyons, and caves are common. Fire occurred on the majority of the land every 4-7 years. 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.

Their migration in great numbers undoubtedly affected the landscape, plant communities, and the cultures of early human inhabitants. Even in 1950 no railway line crossed the entire region. [2] San Angelo, Austin, San Antonio, and Del Rio roughly outline the area. Impacts of Fire Prior to heavy settlement, fire played a major role in shaping the vegetation on the Edwards Plateau. The same sparse conditions that make the plateau one of the most picturesque regions of Texas also make it difficult for farmers and ranchers. In Central Texas this major physiographic break is denoted by the change from Hill Country/Edwards Plateau uplands on the escarpment to the Blackland Prairie on the east. It's hard to overpraise the intense natural beauty and rich history of the . 5. Our results indicate that in the Edwards Plateau, HILF grazing tactics should be employed during the major part of the growing season (May-September) to allow long rest perios for both the soil and vegetation to recover.

Historically, this region was only sparsely populated and human alteration of the environment was limited. The Human Impact on the Natural Environment has become the classic student text on how human activity has changed and continues to change the face of the Earth. Wildfire Physiographic changes have had their impact on human culture as well. 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). The Edwards Plateau is characterized by a combination of tall, medium and short grasses, often intermixed into a woodland or forest setting with hardwood trees such as escarpment live oak, Texas oak, honey mesquite and with coniferous Ashe juniper. According to the Texas Parks and Wildlife Department, all or portions of these 41 counties comprise the Edwards Plateau geographic region:[10], The Texas Water Development Board, a state government agency, includes additional counties all or partly in the Edwards Plateau area:[11].
