Jack Witham has been the on-site Associate Scientist for the Holt Research Forest in Arrowsic, Maine since its inception in 1983. He has a B.S. in Wildlife Management (University of Maine 1976) and a M.S. in Public Policy (University of Southern Maine 1996). At the forest he is involved in research, outreach, stewardship, and supervision; application of research results to regional forestry issues is one of his principal interests. His previous research examined the impacts of pesticide spraying and lake acidification on forest birds and ducks.
In 1989, Jack helped found the Lower Kennebec Regional Land Trust (LKRLT). He is president of LKRLT, which to date has protected more than 1,200 acres of tidal marshes and uplands. In 2000, Jack won the 19th annual Professional Employee Achievement Award, sponsored by the Professional Employees Advisory Council at the University of Maine.
