The Starry Stonewort Collaborative was funded from 2017 – 2021 and has now reached the end of its grant funding and is no longer active. We sincerely thank everyone for their support and involvement. We hope that the many efforts to control starry stonewort across the Great Lakes basin and beyond will continue. The resource and information sections of this website will be kept online for your use, as is (they will not be updated) until October, 2022.   Information and help about invasive species of all kinds can be found at the Finger Lakes PRISM website:
