Trout in Trouble: The Impacts of Global Warming on Trout in the Interior West

Global warming is the single greatest threat to the survival of trout in America's interior west. If nothing is done to reduce human-produced greenhouse gas emissions -- the primary culprit behind global warming -- trout habitat throughout the Rocky Mountain region could be reduced by 50 percent or more by the end of the century, bringing fewer opportunities for anglers to enjoy sportfishing and resulting in serious economic consequences for those who depend on the fishing, recreation and tourism industry for their livelihoods. This July 2008 issue paper by the Natural Resources Defense Council and Montana Trout Unlimited makes clear that we must act now at the national, regional and local levels to reduce our emissions of global warming pollution and adopt other policies that appropriately value healthy rivers, lakes and streams. The paper also includes recommendations for anglers on how to reduce their impact on trout while fishing.
