Forests are a dominant feature of the New England landscape. Join Karen Sebastian and the New England Wild Flower Society as we explore the history, changes in composition, and ecology of the New England forest from the Ice Age through European settlement. Learn to identify native New England trees, their habitats, and their communities. Explore the impact of natural and human disturbances on the forested landscape and learn to recognize stands of different ages. The course, which will generally meet at Garden in the Woods in Framingham, includes two weekend field trips to the Harvard Forest in Petersham and to the Arnold Arboretum. Tuesdays, September 27, October 4, 18, 25, 6:30-8:30 p.m.; Saturday, October 15, 12-4 p.m.; Saturday, October 22, 9 a.m.-1 p.m. $246 for NEWFS members, $290 for nonmembers.
