Research Interests
Use of dendrochronolog to investigate factors involved in tree diebacks and declines. These factors include invasive pests, climate, and site characteristics.

William Livingston is an Associate Professor of Forest Resources, as well as the Associate Director of Undergraduate Programs for the School of Forest Resources.  His research, teaching, and outreach activities revolve around the health of forests both in Maine and across the country. His research involves assessing relationships between climate and tree pests, relating stand history and development to pest problems and tree health in island spruce stands, and investigating the cause of white pine decline. Livingston’s research and teaching activities are based on the concept that Maine’s forests provide an ideal living classroom in which to investigate how land use history affects the health of today’s forests and to evaluate the impacts of invasive species.

The goal of Livingston’s SSI project (Mobilizing to Fight an Invasive Insect) is to study and facilitate the ways that Wabanaki basketmakers, tribes, state and federal foresters, various university researchers, landowners and others come together to prevent, detect, and respond to the emerald ash borer (EAB). The EAB is a potentially devastating invasive threat to all three species of ash trees found in Maine, and since 2002 has moved from Michigan east to New York.
