"Changing Forest Dynamics — Told Through Plots and Tree Rings"
David A. Orwig is a Senior Ecologist at Harvard Forest who studies how forests grow, change, and recover from disturbance. His work uses tree rings and long-term monitoring to track the effects of storms, land use, and invasive insect pests on forest health and diversity. He leads a major Harvard Forest project that maps and measures 120,000+ trees and shrubs to reveal how New England’s woodlands are evolving.
