Though schooled in classical botany, medical biochemistry, organic and radio-nuclear chemistry, as well as experimental surgery, Diana Beresford-Kroeger’s thoughts about trees are anything but classical. She has a collection of ideas, some radical, for how trees can be used to affect climate change as well as human health. According to Beresford-Kroeger, we have yet to fully understand the function and contribution of trees. In this lecture Diana will espouse the intrinsic values of particular trees, explain her hopes for reforesting the planet, and share some of the lore that fuels her passion to continue her research on trees. This lecture, taking place Thursday, May 20, from 7 – 8:30 pm in the Hunnewell Building of the Arnold Arboretum in Jamaica Plain, is co-sponsored with The Wellesley College Friends of Horticulture, and costs $15 for members of the sponsoring institutions, $20 for non-members.
