Fire Ecology

Research Questions
Although savannas, prairies and many wetlands are known to be fire-dependent, there is much debate concerning the frequency and intensity of repeated fire required to maintain plant species composition and structure. Our work asks how different fire frequencies regulate richness and composition of prairie and fen vegetation, how they structure woody vegetation, and how they affect fire-sensitive functional groups.
