Climate Change

Climate change is altering aquatic ecosystems via changes in precipitation patterns, stream flow, temperatures, sea level, and water chemistry, and these changes are accelerating rapidly. These shifting ecosystem drivers are forcing managers to evaluate the potential impacts of climate change on riverine and coastal ecosystems, and to ask whether and how restoration plans or project designs should be altered to accommodate climate change. The key aim of our climate research is to guide managers toward actions that ameliorate climate change effects or increase riverine ecosystem resilience, and to design restoration projects that can remain effective despite future changes to peak flows, low flows, or stream temperature.

Our climate change research focuses on two main topic areas:
