Current Research

I am studying the population dynamics, breeding system, habitat requirements of, and fire effects on rare plants in longleaf pine communities.Specifically, I am working on Macbridea alba, Harperocallis flava, Scutellaria floridana, and Echinacea laevigata (not longleaf systems).I am also working in the fall-line sandhills of South Carolina to develop strategies for restoring structure and composition in the ground layer vegetation of altered longleaf pine communities.Sandhills work includes evaluating the effects and interactions of mechanical treatments and prescribed fire on midstory reduction, and describing life histories and establishment requirements for common sandhills herbs.I am working with others to develop a monitoring strategy for Allium tricoccum (ramps) and to model population processes of this species in the Southern Appalachians.

A Roadmap to Recovery for Degraded Longleaf Pine Plant Communities

Less than 3 percent of the historical longleaf pine ecosystem remains; although much of the southeastern United States has the potential for rec ...
