Baylor University Press, Waco, Texas. Non Technical Summary Typically it is unclear why certain wildlife are either becoming more rare (e.g., endangered species) or abundant (e.g., pests) than human society would prefer, let alone how one might formulate and implement natural resource policies to successfully reverse these trends.

Hill Country, and we welcome you to our family. 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. The inner portion is underlain by granitic and metamorphosed pre-Cambrian rocks; the outer portion, rimming the granitic outcrops, is underlain by Paleozoic sedimentaries that dip beneath the surrounding and geologically younger Comanchean limestones. 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 Diagram illustrating the interaction between biodiversity and geographic scale ..4 Figure 3. the Edwards Plateau (area 11).
