John Campbell

Research Ecologist, U.S. Forest Service



John Campbell is a Research Ecologist with the US Forest Service, Center for Research on Ecosystem Change in Durham, New Hampshire. His work unit manages the Hubbard Brook Experimental Forest where he is involved in maintaining the long-term hydrological and meteorological record. He received B.S. and M.S. degrees in Natural Resources from the University of New Hampshire and a Ph.D. in Environmental and Forest Biology from the State University of New York – College of Environmental Science and Forestry. His research focuses on hydrological and biogeochemical processes in forest watersheds that affect water quality and quantity. His work includes analyses of long-term field measurements, shorter-term field experiments, laboratory studies and modeling, and has been performed at multiple scales ranging from small plots to global syntheses. The goal of his research is to understand ecosystem responses to natural and human disturbances to help inform land management decisions and policies.

Gary Lovett

Forest Ecologist, Cary Institute of Ecocsystem Studies


Gary Lovett is a Forest Ecologist at the Cary Institute of Ecosystem Studies and the lead Principal Investigator for the Hubbard Brook Long Term Ecological Research (LTER) program. He received a B.S. in Biology from Union College and a Ph.D. in Biology/Plant Ecology from Dartmouth College. His research focuses on how disturbances—particularly air pollution, introduced pests and pathogens, and climate change—impact forest ecosystems. He does field research on these topics in New York's Catskill Mountains and Hudson Valley, and at the Hubbard Brook Experimental Forest. 




Topic: Invasive Forest Pests
Non-native forest insects and diseases imported through global trade are one of the most severe and urgent threats to the health of Northeastern forests. These pests cost the country billions of dollars each year and cause serious ecological damage. This talk will discuss the background of the problem, the ecological and economic consequences, and what can be done to prevent new forest pests from entering the country.

Lindsey Rustad

Team Leader/Research Ecologist, U.S. Forest Service



Lindsey Rustad is a Research Ecologist with the US Forest Service in the Northern Forest Science & Applications unit in Durham, New Hampshire, and the Forest Service Team Lead at the Hubbard Brook Experimental Forest. She received a B.A. in Philosophy from Cornell University, an M.S. in Forest Science from the Yale School of Forestry and Environmental Science, and a Ph.D. in Plant Science from the University of Maine. Her research investigates how human disturbances are impacting the forests of northeastern North America, particularly through climate change and acid deposition. Her approach emphasizes the need for multidisciplinary collaboration in order to understand how ecosystems are responding to global change. Dr. Rustad is also passionate about integrating art and science to share ecological data with a broader audience.



Topic: Freezing Trees: Impacts of Ice Storms on Northern Forests

Ice storms are a major cause of distrubance in the Northeastern US, striking as frequently as every 2-5 years. But these storms are difficult to predict—scientists don't know when or where they will occur next. Despite their influential role in shaping forest ecosystems and the services they provide, knowledge of ice storms remains relatively limited. This talk describes the findings of a new study at the Hubbard Brook Experimental Forest that is using a suite of tools, including creating artificial ice storms, to study the impacts of these storms on northern hardwood forests. This research is providing the scientific community, land managers, and the concerned public greater insight on the effects of these powerful, frightening, and curiously aesthetic extreme winter weather events.
