Green crabs are very common in Massachusetts. If you find a crab shell on the beach in New England, chances are it belonged to a green crab. Green crabs contribute to coastal erosion by burrowing through marsh grass, prey upon shellfish found at the beach, and uproot eelgrass in surrounding bays. However, this species is also a delicacy and eating this delicious crab could help mitigate its environmental impact.

During the summer of 2021, GreenCrab.org, with support from Save the Harbor/ Save the Bay and the Department of Conservation and Recreation’s Better Beaches Grant Program, presented six pop-up events on beaches in the Metro Boston area. The pop-up series informed beachgoers about green crabs, an introduced species that causes major problems for local sea life and coastal environments. Pop-ups featured a sculpturally modified tent crafted from repurposed fishing materials by Boston-based public artist Carolyn Lewenberg, and free green crab coloring books created by Boston-based graphic designer Eileen Riestra.
