“…The refined measures allow a more-precise assessment of risk but require much additional data processing (e.g., to delineate riparian areas). The use of more-refined measures is not uncotnmon (Wang et al 2008, Brown andFroemke 2010). However, Falcone and colleagues (2010) recently used independent measures of watershed degradation to assess the utility of different sets of Stressors and found that the refined measures do not tend to contribute much to an overall assessment of risk, in part because of the high correlations between the coarse and the corresponding refined measures.…”

Water quality is a continuing national concern, in part because the containment of pollution from nonpoint (diffuse) sources remains a challenge. We examine the spatial distribution of nonpoint-source threats to water quality. On the basis of comprehensive data sets for a series of watershed Stressors, the relative risk of water-quality impairment was estimated for the over 15,000 fifth-level watersheds in the contiguous United States. A broad division emerged at about the lOOth meridian, with eastern areas typically under higher stress than western areas, reflecting the generall higher housing, road, and agriculture densities and higher levels of atmospheric deposition in the eastern division. Recent trends in some Stresso are encouraging, but the prospect offurtlier substantial population growth indicates continued pressure on water quality, suggesting that renewed focus on controlling nonpoint-source pollution will be needed if the goals of the Clean Water Act are to be attained.

“…Land uses in Great Plains watersheds include livestock grazing, row-crop agriculture, planted pasture, urban areas, roads, dams and reservoir development, and energy development (Brown and Froemke 2010;Reeves and Mitchell 2012;Smith et al 2014). The proportion of rangeland permanently converted to other uses varies from 8 percent in Wyoming to 56 percent in Nebraska; at the county level, loss of rangeland varies from 0 to 100 percent (see figure 11 in Reeves and Mitchell 2012).…”

“…Problems with sediments, nutrients, and toxins have been ranked very low for Shoshone watersheds (Brown and Froemke 2010). Water quality in a few watersheds is of concern due to mining activity and these watersheds are targeted for mitigation through watershed improvement plans (USDA Forest Service 2011a).…”

The Shoshone National Forest (Shoshone) covers 2.4 million acres of mountainous topography in northwest Wyoming and is a vital ecosystem that provides clean water, wildlife habitat, timber, grazing, recreational opportunities, and aesthetic value. The Shoshone has experienced and adapted to changes in climate for many millennia, and is currently experiencing a warming trend that is expected to accelerate in the next century. Climate change directly and indirectly affects the Shoshone's high-elevation, mountainous terrain that supports unique and sometimes rare ecological components. Several vulnerable and very responsive resources and processes on the Shoshone could interact to produce unforeseeable or undesirable ecosystem changes, highlighting the need to identify potential resource vulnerabilities and develop adaptation pathways and flexibility in resource management options. The objective of this report is to synthesize the current understanding of the paleo and historical climate of the Shoshone as a reference point, determine what future climates may look like, and what the effects of future climate may be on natural resources. This information allows for the identification of vulnerabilities and information gaps, thereby aiding the development of adaptation tools and strategies.
