By investigating microfossils (pollen, diatoms) and other deposits (e.g. charcoal) that accumulate in calm sedimentary environments such as natural ponds and wetlands, it is possible to reconstruct changes in plant communities, climate, and disturbance processes over thousands of years. We collaborate with scientists at the Harvard Forest and Emerson College to reconstruct environmental change.

Current Projects (led by Wyatt Oswald):

• Post-glacial vegetation change in New England in response to climate change, soils, and topography

• Holocene vegetation and fire history at Umpawaug Pond in Redding, CT
