Join naturalist and avid outdoor enthusiast Jeff Adams for a winter walk featuring identification tips and natural history facts for some of the trees and shrubs along Walden's shore. We’ll discuss different techniques for identification of bare trees/ shrubs like branching, buds, bark, galls, and persistent leaves and fruit. We may also see some non-woody plants that remain erect in winter. Sturdy hiking boots are recommended. Registration required, with a maximum of 25 people. After the first 25 sign ups, the others will be wait-listed. This event is co-sponsored by the Friends of Walden Pond. Email walden.programs@mass.gov to register, or call 978-405-2082.
