Our mission is to protect the natural and agricultural resources of Long Island and Staten Island by reducing the threat of invasive species.

The Long Island Invasive Species Management Area (LIISMA) is a voluntary association of public and private land managers working together to prevent the spread of invasive species.

We recently spent time working on a restoration project aimed at building resilience against invasive swallow-wort by introducing native plant species that can help support healthier, more diverse habitats. Restoration efforts like this play an important role in strengthening ecosystems and supporting local biodiversity for years to come.

A huge thank you to Long Island Native Plant Initiative (LINPI) and Dropseed Native Landscapes for their generous native plant donations, which helped make this project possible.

Our recent Partners Meeting & Workshop was a complete success! SWIPE to see what we got up to…

Highlights from the day:

Kassidy Robinson (LIISMA, Conservation Area Manager) showed us how quick action on emerging Phragmites stands at Bellows Pond supports native plants populations.

Arden Blumenthal (NYNJTC Conservation Dog Program Coordinator) and her canine partner, Peat “The Kool-Aid Man”stole the show with a live demo on how conservation dogs are sniffing out invasive species aiding the the detection of emerging species!

Michael Farina (Conservation Biologist) walked us through the Marine Nature Study Area, giving us a reminder of why persevering our rare coastal ecosystems is so crucial.

Thank you to everyone who joined us!
