What can the presence (or absence) of greenery teach about the layered history of a place? Together, we walk and analyze the changing landscape, guided by evidence from significant trees in the neighborhood. The discussion addresses local inhabitants’ relationship to native plants over generations. This Native Plant Trust outdoor session with Courtney Allen takes place Wednesday, September 30 from 1:30 – 3:30. $30 for NPT members, $36 for nonmembers. Masks required. Meeting location will be shared following registration at http://www.nativeplanttrust.org/events/tracing-landscape-history-cambridge/
