During the summers of 2005 and 2006 the U.S. Geological Survey, in cooperation with the Texas Commission on Environmental Quality, evaluated nutrient and biological conditions in small streams in parts of the Edwards Plateau of Central Texas. Human activities are usually considered to have had impacts on forest degradation and/or changes of forest composition in the past. [2] San Angelo, Austin, San Antonio, and Del Rio roughly outline the area. The central and northern portions of the Edwards Plateau as well as the upland ridges of the southern and eastern portions contain round, often rolling hills. It hasnt been easy. Its distinctive physical features, especially its lack of deep soils suitable for farming, cause the Edwards Plateau to be an outstanding grazing region of Texas. Even in 1950 no railway line crossed the entire region. 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. Trans-Pecos. 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).
