Wetland and Aquatic Research Center

Priority Landscapes

Place-based research to understand the biological and physical processes that influences change and management options across large geographic areas of management concern. Current areas of focus includes the Arctic, Chesapeake Bay, Columbia River, Colorado River, Everglades, Great Lakes, Klamath River, Mississippi River, Mojave Desert, Pacific Islands, Puget Sound, Sagebrush Steppe, and San Francisco Bay. Also includes landscape scale assessments such as the Wyoming Landscape Conservation Initiative and development of Rapid Ecoregional Assessments.

Wetland Methane Emissions: Functional-type Modeling and Data-driven Parameterization

To better understand the environmental drivers of methane emissions in tidal saltmarsh, tidal freshwater swamp forest, tidal freshwater marsh, and non-tidal freshwater marsh habitats, researchers are collecting observations of CH4 emissions and porewater concentrations at research sites representative of each of these habitats.
