Long-term weather patterns, including day and night temperatures, precipitation, air pressures, and wind direction, that effect a change in climate is part of a program called “Climate, Trees & Ecosystems,” that is taking place on Thursday, Aug. 22, at 7 p.m. in The Center for Moosehead History, 6 Lakeview St., downtown Greenville.

The program provides a fascinating account of the physiological responses of northeastern forests to long-term weather patterns and an historical overview of the data that has been collected over decades of field research.

Jay Wason, assistant professor of Forest Ecosystem Physiology at the University of Maine, will present information about climate patterns in relation to forests and ecosystems. Sean Birkel, research assistant professor at the University of Maine and Maine State Climatologist, will provide an overview of Maine’s climate, general impacts, and what may be expected in the future.

Dr. Wason joined the University of Maine School of Forest Resources faculty in 2018. Prior to that, he was a post-doctoral research associate at the Yale School of Forestry and Environmental Studies. His research centers on the physiological responses of northeastern forests to climate conditions. He is especially interested in spruce-fir forests.

Professor Birkel’s expertise is in climate and ice sheet modeling, with research including Pleistocene glaciation, Maine historical climatology, and today’s changes in the environment.
