Forests & Plants


Connie Harrington, Silviculturist & Tree Physiologist

- Ph.D., University of Washington (Seattle)
- USDA Forest Service Scientist
- A silviculturist studies how trees interact with each other and how changing a tree’s neighborhood influences how it grows and the other plants that grow with it. A tree physiologist studies the biological processes that influence tree growth.

Rich Hallett, Forest Ecologist

- Ph.D., University of New Hampshire
- USDA Forest Service Scientist
- A forest ecologist is concerned with the survival of the forests, how trees and people ‘get along,’ and how we can help each other.

Michael Gavazzi, Biological Scientist

- M.S., Virginia Tech
- USDA Forest Service Scientist
- A biological scientist is a jack of all trades. I work with other researchers in diverse disciplines to study forest ecosystems response to prescribed burning, climate change, and natural and man-made disturbance.

Katherine J. Elliot, Forest Ecologist

- Ph.D., University of Maine
- USDA Forest Service Scientist
- A forest ecologist studies interactions among plants, animals, energy, water, and nutrients. A forest ecologist also studies how all of these things relate to patters and processes in forest ecosystems.
