Harpswell Invasive Plant Partnership (HIPP) Workday. Meet at Williams Field on Harpswell Heritages Land Trust’s Curtis Farm, 1554 Harpswell Neck Road, Harpswell. Help restore our native plant habitats. Free pizza afterwards. If you speak French or Portuguese, even better, as we’ll be bringing a refugee family to join in on the work. Bring water, bug repellent, sunscreen, gloves and your favorite gardening hand tools (clippers, hand saws, etc.). FMI email #email@example.com">firstname.lastname@example.org.
