GROTON — As summer fades and cooler temperatures arrive, New England prepares for one of its most spectacular annual displays: the changing of the leaves. But what actually causes the brilliant reds, oranges and yellows that transform the landscape each fall? And why do some years produce more vibrant foliage than others?
Those questions and more will be explored during “The Science of Autumn Foliage with David Govatski,” a virtual program from 7 to 8 p.m. on Tuesday, Sept. 29, via Zoom.
Govatski, a naturalist with more than 20 years of experience, will take a closer look at the science behind autumn color, including why leaves change, which pigments create the various colors and what environmental factors influence the intensity of foliage. He will also discuss the significance of the seasonal transformation, the potential effects of climate change on New England’s fall foliage, and the economic and health benefits the region receives from its annual autumn display.
Govatski spent 33 years with the U.S. Forest Service, working as a forester, silviculturist and forest fire management officer in locations across the country. Since retiring, he has worked as an expedition ship naturalist in Alaska and Iceland. He is also a co-author of “Forests for the People – The Story of the Eastern National Forests” and remains active in conservation and environmental organizations.
The program is being offered via Zoom, and registration is required by visiting the Groton Public Library’s calendar at gpl.org. Registrants will receive a link to the webinar by email. The program will also be recorded, with a recording emailed to participants within 48 hours. The program is made possible by the Groton Public Library Endowment Trust and presented in cooperation with several area libraries.
