Expertise

Plant Ecology especially the role of fire and grazing in grasslands; The expansion of woody vegetation into grasslands; Landscape Ecology; Influence of humans on ecosystems; The use of Remote Sensing and Geographical Information Systems in Ecosystem Research; Ecological Data Management. We are investigating the following projects: 1. Ecosystems in Transition: Causes and Consequences of Dramatic Shifts in Growth Form Dominance. 2. Long-Term Ecological Research in Tallgrass Prairie: The Konza Prairie LTER Program. A comprehensive long-term ecological research program is being conducted at the Konza Prairie LTER site in NE Kansas. 3. The role of humans in structuring plant communities.
