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. The indicator shows the risk of having impacts from a drought, by taking into account the exposure and socio-economic vulnerability of the area, with . The escarpment and faults also plays a role with regional water resources. Rio Grande wild turkey (RGWT) abundance in portions of the Edwards Plateau has declined steadily since the late 1970s as compared to other areas of the Edwards Plateau where populations have exhibited no trend. However, the team also turned its attention to another area nearby, where it discovered significantly more, and larger, artifacts that were also older than Clovis.. Columbia Plateau Human Impact. The Tibetan Plateau, an environmentally sensitive area, has witnessed a high intensity of human activities since the late Neolithic, but the evidence is still incomplete concerning how human activities affected the environment, Fish and Wildlife Service Rolling Plains West of the Cross Timbers and Prairies and north of the Edwards Plateau is the Rolling Plains ecoregion. Bounded by the Pecos River to the west and the Colorado river to the east, Edwards Plateau also borders the Llano Estacado to the north.
