Research conducted in the Stream Ecology Center focuses on rivers and streams, but more generally on the ecological linkages between water, land and people. Reciprocal connections such as those between streams, floodplains, and riparian forests are critical to watershed ecosystems, and they couple land and water in their vulnerability to the agents of global environmental change. Research led by Dr. Baxter is aimed at improving our understanding of the basic nature of such connections and the consequences of their disruption by human activities, but also contributing to better-informed conservation and stewardship.
