Historically, this region was only sparsely populated and human alteration of the environment was limited. but the DOI has constant concern regarding the impact of such a decision due to the vast number of areas this species inhabits. Understanding long-term environmental changes under natural and anthropic forces is helpful for facilitating sustainable development. 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. Without competition for light, water, and minerals from trees, the grass extended across central Texas. To see what the plateau originally looked like, head out to its western portion, in West Texas.

Prior to heavy settlement, fire played a major role in shaping the vegetation on the Edwards Plateau. [6] Mechanisms for spring association of fishes is not fully understood, but thought to mediated by water temperature.

Human-induced landscape transformations have important implications for the maintenance of biodiversity. Drought If a drought were to occur in my region there would be many consequences. TSHA | Edwards Plateau - Handbook of Texas Drought is a common occurrence in this region that periodically has long term affects on wildlife populations and habitat resources. Native plants, on the other hand, evolve naturally in one' particular region and are generally well-adapted, low maintenance, competitive with weeds, and use little water. These techniques include using sheep to root out some invasive species, clearing land for smaller herds of cattle. impact and influence soil surface properties such as bulk density, organic matter content, and aggregation (Osborn 1954, Copeland 1963, Blackburn 1975, Meeuwig and Packer 1976, Blackburn et al.
