The arrival of European settlers in the 1800s marked the beginning of a rapid period of change for both the people and the landscape of Edwards Plateau. 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. Because of the elevation drop off at the edge of the Edwards Plateau as well as its location between the dry western plains and the moist prairies and woods to the east, average rainfall varies widely from 23 inches per year to 35 inches per year.
