Starry Stonewort Collaborative

The Starry Stonewort Collaborative is a program that brings together and increases the capacity of researchers, collaborators and concerned citizens to further understand and control the invasive aquatic species Starry Stonewort (Nitellopsis obtusa or SSW). Left unchecked this invader can harm natural ecosystems, push out native species, and clog up waterways.

To help fight SSW, the Collaborative uses a framework of 40+ scientists, stakeholders, and resource managers from across the Great Lakes basin who supply local support through outreach efforts, resource exchanges, and data collection. Through these partners, the Collaborative runs programs like the Macrophyte Survey, which utilizes citizen scientists to gather data on the location of aquatic invasive species, and trains an ever increasing number of people about SSW. For additional support, the Collaborative uses a smaller Expert Panel who reviews papers, recommends control and management practices, and provides educational webinars.

The Collaborative also works with other organizations, like the United States Geological Survey Nonindigenous Aquatic Species program (USGS-NAS) and iMapInvasives, to create more comprehensive and accessible records of the locations of starry stonewort infestations.
