Abstract

    This is a field-based study of intermediate wind disturbance (i.e., blowdown) effects on forest structure, composition, and carbon dynamics. Under Professor William Keeton's supervision, field crews collected data at four sites at multiple points in time. One of the primary outcomes is a journal article in Ecological Applications.
