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…
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.

Our Aquatic Invasive Species Learning Experience (AISLE) has empowered over 100 participants to protect New York’s freshwater ecosystems. Through hands-on learning and the Water Protectors initiative, volunteers are adopting local waterbodies, monitoring for invasive species, and building a community of informed stewards. With Year three on the horizon, AISLE continues to grow—and you’re invited to join the movement!
New York State is offering exciting funding and research opportunities to support environmental conservation and invasive species management.
Gardeners and landscapers in the St. Lawrence and Eastern Lake Ontario region should be alert—box tree moth is on the move. First detected in New York in 2021, this invasive pest can defoliate and kill boxwood shrubs within weeks. Its caterpillars hide deep in the foliage, making early detection critical. Cornell IPM offers resources for identifying and managing this pest, including organic treatment options and alternative plant suggestions.
The Nature Conservancy, in partnership with the Jefferson County Soil and Water Conservation District, is leading a bold reforestation effort in Jefferson County—one of New York’s top areas for tree planting. As part of the state’s goal to plant 680 million trees by 2040, this collaboration is testing innovative landowner incentives and planting strategies to scale up reforestation, restore ecosystems, and fight climate change.
Parrotfeather (Myriophyllum aquaticum) may look stunning in garden ponds, but this invasive aquatic plant is spreading rapidly across North America. With its feathery foliage and ability to form dense mats, it outcompetes native species and disrupts ecosystems. Recently detected in Onondaga County, early action is key to preventing its costly spread and protecting New York’s waterways.
Researchers at SUNY Oswego’s Aquatic Conservation Laboratory are teaming up with SLELO PRISM to track invasive species in the Lake Ontario watershed using eDNA technology. This innovative approach helps detect threats early—before they spread—boosting efforts to protect native ecosystems.
A new initiative, Seeds of Stewardship, is taking root across Jefferson, Lewis, and St. Lawrence counties. Led by Cornell Cooperative Extension of Jefferson County, the project aims to build a regional native seed network that supports eco-systems, restores habitats, and strengthens our connection to the land and water.
The New York Natural Heritage Program manages iMapInvasives, tracking invasive species and their impact on rare species. A shared map viewer helps PRISM staff target biodiversity protection efforts.
The New York Natural Heritage Program is collaborating with organizations in Great Lakes states to enhance knowledge of vernal pools by utilizing new mapping tools and community science, and recruiting volunteers for a new community science program called NY POOLS!
The energy was electric at SUNY Oswego’s Sheldon Hall Ballroom on June 12th, as over 100 passionate attendees gathered for the most successful Eastern Lake Ontario Invasive Species Symposium to date! With 20 dynamic presenters, 14 engaging exhibitors, and a keynote address from the renowned Robin Wall Kimmerer, the event was a vibrant celebration of collaboration, innovation, and ecological stewardship.

At SLELO PRISM, collaboration is more than a strategy, it’s our foundation. This season, we took a meaningful step to strengthen that foundation by launching our 2025 Partner Engagement Survey.
