Edwards Plateau
The Edwards Plateau area includes 1.45 million acres known as the Granitic Central Basin in Llano and Mason Counties. The Balcones Escarpment forms the distinct boundary of the Edwards Plateau on its eastern and southern borders and outlines what is known as the Texas Hill Country.The area is a deeply dissected, rapidly drained stony plain having broad, flat to undulating divides. Prior to modern settlement, vegetation was grassland or open savannah-type plains with tree or brushy species found along rocky slopes and stream bottoms.
