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. The grassland savanna supported a diversity of floras and grasses, and a variety of unique species and migrating wildlife made the region their home. Natural fires that used to clear out undergrowth were quelled by settlers. Such a decision would have potential negative impacts on the natural resource industry. day!

Noxious weeds, from cheatgrass to knapweed to Russian olive, displace or alter the functioning of native plant communities. Because of the abundance of data available to us, we were able to generate estimates of detection probability that were able to vary based on effects of time and environmental conditions. Those who survived learned to mitigate their effect on the land, implementing smarter grazing techniques and avoiding overuse. Over time, people have filtered into the 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. [2] San Angelo, Austin, San Antonio, and Del Rio roughly outline the area.
