Invasive Plants
During the recent years, we controlled invasive plant populations on eight islands (Inner Sand Island, Ship Island, Bar Island, Trumpet Island, Little Marshal Island, Upper Flag Island, Compass Island, Spectacle Island). Our methods to control these invasive plants favored, when possible, removal of flowering stems and seed heads to prevent establishment of new plants, digging or pulling of whole plants, as well as, depending on site location, a combination of applying seawater, foliar spraying with vinegar-based solutions (20% vinegar with clove oil and citrus oil), and application of aluminum sulfate. Application of herbicides were used to control some of the invasive species in certain locaitons as well, and methodologies were site and species specific. We will continue the collaborate closely with Maine Coastal Islands NWR to control selected populations.
