Dr. Buma is interested in the process of change in natural systems. In particular, his work focuses on disturbances like fire, wind, and landslides, and the subsequent change in species composition and ecosystem functioning. His work spans from Alaska to Chile, generally focusing on high elevation and high latitude forested systems, species migration, and carbon/water cycling. As a National Geographic Explorer, he is also interested in science communication, historical ecology, and telling interesting stories to the public about the natural world.
