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. But go further west on the plateau, and you enter a drier, more desert-like environment with less rain. Livestock were continuously grazed in fenced pastures which disrupted the natural movement patterns of grazing animals. Harmful ways humans impact the Edwards Plateau: 1: People are moving into the region and are taking away the land from the animals 2: The Population of birds is being threatened by the building of reservoirs.

Before modern transportation and the means of tapping underground supplies of water were developed, travel across the Edwards Plateau country was difficult. By and large, however, the Edwards Plateau is erosional with the margins of the region frayed rather deeply so that the plateau as a whole is perceptibly higher than adjacent areas. E. H. Johnson, Human activities are usually considered to have had impacts on forest degradation and/or changes of forest composition in the past.
