Research Interests and Lab Responsibilities
Stephen Smith is a Plant Ecologist at the Cape Cod National Seashore, with expertise in plant physiology and plant community ecology.Stephen received a B.S. degree from Florida State University and an M.S and a Ph.D. from the University of Miami. After spending 5 years working on the restoration of the Florida Everglades, he assumed his current position with the National Park Service in 2002. Stephen's current activities are focused on understanding the dynamics of spatial and temporal variability within plant communities in all the different ecosystems (forests, heathlands, dune grasslands, vernal ponds, lakes, salt marshes, lagoons, nearshore marine systems) within the Seashore. A large part of this work involves assessments of salt marsh ecosystem structure and function in response to tidal restoration and causes and consequences of salt marsh dieback.Other responsibilities include exotic and rare plant management.
