Creating resilient lands and waters while protecting biodiversity through invasive species prevention and management

The St. Lawrence-Eastern Lake Ontario (SLELO) Partnership for Regional Invasive Species Management (PRISM) is in cooperation with The New York State Department of Environmental Conservation and more than twenty-three regional partner organizations. Our mission 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.

You can help prevent and manage invasive species, too! Join our protectors by taking the Pledge to Protect against invasive species. We’ll arm you with the information you need to protect our region, based on the outdoor environments you live, work and play in. Protectors receive monthly emails with simple steps to take, education on invasive species and badges to share on social media. Read More…

Discovering populations of invasive species before they become too large to manage, known as Early Detection, gives a strategic advantage to prevention and management initiatives. You can aid early detection efforts in the St. Lawrence Eastern Lake Ontario Region by joining our Invasive Species Volunteer Surveillance Network (VSN), and by joining other volunteer opportunities we offer.  Read More…
