Hosted by the St. Lawrence Eastern Lake Ontario Partnership for Regional Invasive Species Management (SLELO PRISM), the Eastern Lake Ontario (ELO) Invasive Species Symposium provides an opportunity to connect with field professionals and expand your knowledge of invasive species management.
The symposium will be held on June 12th, 2025 at SUNY Oswego’s Sheldon Ballroom in Oswego, NY. This year’s symposium theme is Adaptive Approaches for Terrestrial and Aquatic Invasive Species Management focusing on Traditional Ecological Knowledge (TEK), climate change, and restoring biodiversity.
