Notably, the impact of increasing cohort N on T max is attenuated logarithmically (ln N) . Cattle, for instance, are grazed on the typical mesquite-shrub, short-grass areas, characterized by deeper soils. The settlers lived on farms and ranches, and their animals changed the native plants in the area. First it was used and wandered about by Jumano and Coahuiltecan groups, then the Apacheria extended into the Southern Plains by the forerunners of the Lipan and Mescalero Apaches. but the DOI has constant concern regarding the impact of such a decision due to the vast number of areas this species inhabits.

The behavioral evolution of humans to harness and apply fire has shaped the structure and function of grasslands on Earth for tens of thousands of years, but many modern societies have evolved past this legacy (Pyne 2001, 2007).This change in human behavior, combined with other sources of anthropogenic change such as climate change, the Most of the region's physical and cultural landscape has little in common with the rest of the state.

On the east and south, the Balcones Escarpment forms a distinct boundary to the Edwards Plateau, but on the west the pla- teau blends into other regions. The impact of grazing on small rodent populations in particular may be significant because of their functional role in grassland ecosystems (Carey and Johnson, 1995).

Impacts of Fire Prior to heavy settlement, fire played a major role in shaping the vegetation on the Edwards Plateau. The land began to change from a grassland to a brushland. Over time, the rivers, creeks, wind, and rain that cut through the limestone and shale have eroded the flat plateau, transforming it into the distinctive series of rolling hills that Texans know today as the Hill Country. The clear and fast-flowing headwater streams of the Central Edwards Plateau Rivers NFCA meet the habitat requirements of Guadalupe Bass, while river base flows are largely dependent on spring. Plateaus are built over millions of years as pieces of Earth's crust smash into each other, melt, and gurgle back toward the surface. These hills and surrounding valleys of the Hill Country are a direct result of limestone washing away. Noxious weeds, from cheatgrass to knapweed to Russian olive, displace or alter the functioning of native plant communities.

Springs and creeks found in these canyons are typically lined with baldcypress, sycamore, and black willow. 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. Physiographically, the Edwards Plateau is distinguished from the rest of the Great Plains precisely because it is not almost entirely flat upland. Nearby urbanization will make adaptation difficult or impossible for native species. The nearby Edwards Plateau receives slightly more rain, enough for trees adapted to a dry climate to survive.

Cedar was restricted to overgrazed areas along rivers and streams, and in areas of shallow soils and steep canyons where fires did not occur frequently. These animals have selective eating habits and eat the more desirable plants first and leave the less desirable plants for last. Geologic records indicate that Texas experienced large climate changes on millennial time scales in the past, and over the last thousand years, tree-ring records indicate Though most know of the Texas Hill Country, the Edwards Plateau is less familiar. Overgrazing of cattle, sheep, and goats also led to the erosion of prairie land and the encroachment of shrubby species like mesquite and ashe juniper. We set three sampling sites from an altitude of 3600-3700 m in October-November 2020 (Fig. 7. Those who survived learned to mitigate their effect on the land, implementing smarter grazing techniques and avoiding overuse.
