Squam Watershed Invasive Species Collaborative

Five organizations form the Squam Watershed Invasive Species Collaborative (SWISC), an effort to combat terrestrial invasive species in the Squam Watershed through both education and removal efforts. By combing expertise, volunteer recruitment, and work days, the members of the collaborative will better manage Squam Watershed properties for invasive species.
