Those who survived learned to mitigate their effect on the land, implementing smarter grazing techniques and avoiding overuse. The remoteness of the region was amplified by the absence of the railroad as late as 1950. Prior to heavy settlement, fire played a major role in shaping the vegetation on the Edwards Plateau. Livestock were continuously grazed in fenced pastures which disrupted the natural movement patterns of grazing animals.

Human-induced landscape transformations have important implications for the maintenance of biodiversity. The Edwards Plateau is a geographic region at the crossroads of Central, South, and West Texas. Anglo settlement brought German farming communities, and adventurous livestock ranchers which have been since identified with Texas. The distribution of livestock in the region serves to indicate the various types of the natural environment, particularly as reflected in the different kinds of natural vegetation. 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.
