The Chapter hosted its fifth annual Earth Day activity last spring, an event that now involves kids in large groups, and is in evidence in more than half of the Tri-County Regional School Board’s (TCRSB) schools. During the event, which is organized and supported by the Chapter, students learn about watershed ecosystems and habitat management. TCRSB teachers, with Tusket River TUC members at their side, take their classes out to do various age-appropriate activities designed to introduce young people to the concepts of watershed stewardship.
