Plateaus are built over millions of years as pieces of Earth's crust smash into each other, melt, and gurgle back toward the surface. 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. Edwards Plateau Handbook. The regions history is as colorful as the history of Texas itself, a story of changes and challenges, and of a difficult and unwelcoming landscape that helped forge the rugged nature of the Texas spirit.

The Edwards Plateau brushlands consist of woody plants mostly less than nine feet tall which are dominant and growing as closely spaced individuals, clusters or closed canopied stands (greater than 10% canopy cover). Less visible was the effect these settlers had on the landscape. Frequent fires were part of the natural cycle of birth and rebirth, helping to curtail the spreading of shrubs and cedar.

Trees of the savanna include junipers (locally called mountain cedar), oak species scattered over grasses, a vegetation type historically shaped by droughts and regular fires. 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.

Our results indicate that in the Edwards Plateau, HILF grazing tactics should be employed during the major part of the growing season (May-September) to allow long rest perios for both the soil and vegetation to recover. Grass fires would regularly rejuvenate the landscape, burning seedling trees, allowing the grass to flourish. Noxious weeds, from cheatgrass to knapweed to Russian olive, displace or alter the functioning of native plant communities.
