Teaming Up To Stop The Spread Of Invasive Species

The mission of the St. Lawrence-Eastern Lake Ontario (SLELO) Partnership for Regional Invasive Species Management (PRISM) is to protect native habitats, biodiversity, natural areas, and freshwater resources by using a collaborative and integrated approach to invasive species management with emphasis on: prevention, early detection, rapid response, education and outreach.

Our work is a collaborative effort among multiple partners. Our work is focused on priority initiatives identified by our partnership. These priorities guide our strategic planning and actions and are aligned with our mission to protect our lands and waters from the impacts of invasive species. Read More..
