Boston is celebrating World Wetlands Day throughout the month of February with a series of self-guided walks at inland wetlands and urban wild sites at Canterbury Brook, the Roslindale Wetlands, and Sherrin Woods. Boston’s wetlands are a critical part of green infrastructure contributing to climate resiliency and reducing heat island effects. Mayor Walsh and the Boston City Council have proclaimed February 2nd as World Wetlands Day. The day commemorates the signing of the Ramsar Convention, an international treaty for the conservation and sustainable use of wetlands and this year is the 50th anniversary.
