The Open Space Committee is seeking volunteers for a day of pruning and other trail maintenance at the Gertrude Cornish Town Forest on Plain Street. Members of the committee and the town’s Conservation Land Stewardship Group, along with other volunteers, will meet at the forest at 9 a.m. Saturday. Conservation agent Jennifer Carlino said the town has an $1,840 state grant to work with a forester, who will be thinning white pines in the forest before volunteers do the pruning. If enough people participate, the committee hopes to also mark new trails at the town-owned Lincoln Woods Conservation Area, which abuts the forest. “It’s great to get people out in the forest and to show how forest ecology can benefit from forestry management,” she said. “And it’s fun.” The event lasts until 2 p.m. Volunteers should bring water, lunch, snacks, gloves, loppers, pruning shears, a hand saw, and a shovel.
