Eelgrass once grew in abundance in Barnegat Bay, New Jersey, where it was harvested, dried and used for insulation in houses, such as the governor's summer mansion in Island Beach State Park. A blight decimated the eelgrass, which ended harvesting of the plant. The plant is making a gradual comeback.
