Karl Flessa's research interests include conservation biology, historical ecology and invertebrate paleobiology. His current research focuses on the policy and effects of transboundary environmental flows, the environmental consequences of water diversions on the Colorado River Delta, restoration of wetland and estuarine habitats, transboundary ecosystem services and how geohistorical records can be utilized in conservation biology.
