These hills and surrounding valleys of the Hill Country are a direct result of limestone washing away. The Edwards Plateau, in addition to facing increased human impact on its environment, is struggling to manage invasive plant species, such as the Eastern Red Cedar tree, and increased livestock grazing. Those who survived learned to mitigate their effect on the land, implementing smarter grazing techniques and avoiding overuse. Students are researching such sites as the oil fields of the Permian Basin in West Texas and limestone quarries on the Edwards Plateau and Aquifer, Utting said. The western portion remains a relatively flat elevated plateau whereas the eastern portion known as the Hill Country is deeply eroded.
