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

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…

-SLELO PRISM SHOWCASE-

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.. 

 

The SLELO PRISM strives to implement successful and innovative projects, delivering targeted approaches to invasive species spread prevention, early detection, management, restoration, and outreach. Learn more about our staff and how our roles support our program. 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…

 Celebrating Volunteers Who Make Conservation Possible

Volunteers are at the heart of conservation success. This fall, SLELO PRISM celebrated their contributions during its first Volunteer Appreciation Event and launched the Volunteer Engagement & Impact Program (VEIP). Designed around the growth of a healthy ecosystem, the program recognizes volunteer service, stewardship, and conservation impact through five achievement levels. Whether restoring habitat, removing invasive species, or supporting community science, volunteers continue to make a lasting difference across the region.

 Species Spotlight: Laurel Wilt

Laurel wilt, a deadly tree disease spread by the invasive redbay ambrosia beetle, threatens several members of the laurel family, including New York’s native sassafras and spicebush. While currently limited to Long Island, tracking its spread remains important for protecting forest health across the state. Read this article to learn what signs to look for and how to report it.

Growing Healthy Watersheds Through Tree Planting and Planning

Jefferson County Soil and Water Conservation District is working hard to strengthen ecosystems across the region. This year, approximately 60,000 trees were planted through collaborative reforestation efforts that improve water quality, wildlife habitat, and climate resilience. At the same time, science-based watershed planning is helping communities identify priorities and prepare for future environmental challenges. Together, restoration and planning are building healthier watersheds and stronger landscapes for generations to come.

Linking Undergraduate Ecology to Conservation Practice

A partnership between SUNY Oswego and SLELO PRISM is giving students hands-on experience in ecological research and conservation. Working at Deer Creek Boat Launch, students are investigating invasive species impacts, collecting field data, and helping restore habitat through direct management activities. Along the way, they are developing valuable research skills while contributing information that can support future conservation efforts. The collaboration demonstrates the power of connecting education with real-world environmental stewardship.

From an Aging Dam to a Living Waterway

Restoring aquatic connectivity requires balancing the needs of native species with the prevention of invasive species spread. Through work on the Little Salmon River and lessons learned from Black Creek, Syracuse University students are exploring how engineering solutions can support fish passage while limiting sea lamprey movement. The project highlights the importance of collaboration, thoughtful planning, and community stewardship in managing waterways. Protecting rivers means considering both ecological restoration and invasive species prevention.

Monitoring From Above

Seeing conservation from a new perspective! Drone surveys help track invasive species, monitor habitat changes, and can improve management efforts in our region. This season, imagery revealed significant expansion of a non-native American lotus population, which led to a collaborative removal effort. Looking ahead, new partnerships and image-recognition tools may further improve monitoring and conservation outcomes. This emerging technology is giving us powerful new tools to protect the landscapes we love.
