On Tuesday, Jul. 23, and Friday, Jul. 26, from 8:30 a.m. to 10:00 a.m., join a group of area volunteers who will learn how to remove invasive plants from Hartman Park while protecting native plants. Volunteers are encouraged to wear long pants and bring their own work gloves, lopping shears, hand pruners, handsaws, clippers, mattock hoes and bottled water. The work parties are sponsored by the Town of Lyme and the Lyme Land Trust. To register, send an email to openspace@townlyme.org, but walk-ins are also welcome. For more information, go here.
