See all events for Earth Month (and Invasive Species Month) here: April is invasive species and earth month! Help remove invasive species with The Discovery Museum at Great Hill conservation land. We will remove as many invasive plants as possible between 1pm to 3pm. Some plants range from easily being pulled from the ground to removing with tools like shovels and pruners. Please sign up and review what to bring HERE. Park at the trail head (204 Main Street) or at the Discover Museum. Note that children must be supervised!
