Tune in today at 10:00 AM! We’re going LIVE for NYISAW to share a behind‑the‑scenes look at our water chestnut (Trapa natans) pull and talk about how this invasive plant forms dense floating mats that crowd out native species and disrupt freshwater ecosystems.

LIISMA is excited to collaborate with our partners at the New York State Department of Environmental Conservation (DEC), highlighting the teamwork that makes it possible.

📅 When: Wednesday, June 10, 2026 at 10:00 AM
📍 Where: Wawapek Preserve (Mowbray Lane, Cold Spring Harbor)
💪 Why: Invasive vines pose a major threat to our woodlands. As they climb, they block out vital sunlight, trap rot-inducing moisture, harbor pests, and can even strangle tree trunks. Come out and help the NSLA reach their goal of freeing 250 trees from destructive vines by July 4th!
