Abiotic and biotic factors reduce viability of a high-elevation salamander in its native range Includes data used to estimate population demographic parameters for an exemplary high-elevation amphibian species, the federally endangered Shenandoah salamander (Plethodon shenandoah). These parameters were entered into a Markov projection model which we used to forecast the future population status of the Shenandoah salamander.

Although projections of water-use estimates are subject to a variety of contingencies, ranging from natural disasters such as droughts and floods to economic booms or disruptions, they provide a basis for planners to evaluate the adequacy of water resources to meet future needs. During 2007, the State of Tennessee experienced a drought that limited water supply to several of the utility systems. As a result, the U.S. Geological Survey (USGS), in cooperation with the Tennessee Department of Environment and Conservation,...
