Get a head start on invasive control this year by learning to identify invasives in the early season. This New England Wild Flower Society course, co-sponsored by the Arnold Arboretum of Harvard University, provides an introduction to about 40 of the most common invasive non-native plants in our local landscapes. Through lecture, discussion, power-point presentation, herbarium specimens, and a walk outside at Garden in the Woods in Framinham, become familiar with identification clues as well as the habits of a number of these plants that are so disruptive of natural ecosystems. Discuss management techniques for many of these species, on both a home and a landscape scale. The “Invaders†issue of the Society’s magazine as well as the Field Guide to Invasive Plants in Massachusetts will be available for purchase at a discount. The session will take place Sunday, April 17 from 12:30 – 4:30, and will cost $48 for members of the sponsoring organizations, $58 for non-members. Register online at www.newfs.org.
