Climate change affects stream temperature, which in turn affects fish and other aquatic organisms. A new temperature model developed via collaboration between researchers at the Rocky Mountain Research Station's Aquatic Sciences Laboratory in Boise and the Australian Commonwealth Scientific and Research Organization can accurately predict stream temperatures, rates of climate warming and habitat loss for sensitive species across large river networks. The model integrates temperature information, commonly collected by the USFS and other agencies with GIS and remote-sensing technologies to give decision-makers an expanded base of information to consider when making investment decisions for stream-restoration projects. The model was first developed to estimate the effects of climate change on streams draining the Boise River Basin in central Idaho and has recently been extended to provide historical and future temperature predictions for all streams on the Payette National Forest. The temperature model advances the water resources protection and enhancement goal that Agriculture Secretary Tom Vilsack and Forest Service Chief Tom Tidwell set forth in their shared vision for America's forests.
