Wetlands are ecologically important yet at-risk ecosystems. Wetlands provide critical services for natural communities and human society, including nutrient cycling, wildlife provisioning, water storage & filtration, carbon sequestration, agriculture & recreation, and core habitat for a wide range of species. Wetlands challenge our current scientific capacity because of their sheer number (10,000’s-100,000’s for the Pacific Northwest alone), their wide range of sizes (<100 to >10,000 m2), and dynamic nature (intermittent to permanent). They are also thought to be among the most sensitive ecosystems to climate change via changes in temperature and precipitation and resulting changes in hydroperiod and water temperature. Our research aims to develop new approaches and technical tools that are needed to support the conservation and sustainable management of wetlands in a changing climate. These include: 1) new methods for mapping wetlands and monitoring and reconstructing wetland hydroperiod using remote- sensing approaches, 2) the first generation of projections of hydrologic impacts to Pacific Northwest wetlands under climate change, 3) field-based hydrologic monitoring of wetlands in three PNW ecoregions, and 4) integration of 1-3 with ecological data to forecast climate change impacts to wetland ecosystems. We are particularly interested in the effects of climate change on amphibians such as the Cascades frog.
