ST. LAWRENCE EASTERN LAKE ONTARIO PARTNERSHIP FOR REGIONAL INVASIVE SPECIES 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.

Winter forests hold a quiet magic, and at the heart of that beauty stands the eastern hemlock—an essential tree now facing a growing threat. This blog explores why hemlocks matter, what’s at risk if we lose them, and how you can take action this winter to help protect these irreplaceable trees.
The Nature Conservancy and SLELO-PRISM are excited to announce an opportunity for our partners to submit nominations for special project funding!
SLELO PRISM holds our annual Virtual Hike Challenge (VHC). The challenge, happening November through March, pairs winter hiking with simple instructions to help keep an eye out for hemlock woolly adelgid (HWA). HWA is an invasive forest pest that is confirmed to be present in Oswego County and is spreading along the Eastern Lake Ontario shoreline.
