Recently, we met with our new Lower Hudson PRSIM partner, Sarah Martinez, of The Nature Conservancy in New York. Sarah gave us a tour of Eugene and Agnes Meyer Preserve in Westchester County, where she showed us the preserve’s meadows, which are mowed every other year to tamp down the growth of invasive species and promote native species (like milkweed and goldenrod), as well as its forest, where they set up a Hemlock Health Monitoring Plot this year for hemlock woolly adelgid.

We are eager for them to discover successful meadow management tips from our partners and see how the health of their hemlocks changes over time. Thank you, Sarah, for showing us around and sharing your knowledge about this lovely spot!

Last month, we held our spring Lower Hudson PRISM Partner Meeting at Cornell Cooperative Extension of Rockland. With education and outreach as the theme, the meeting was chock-full of presentations, workshops, tabling demonstrations, and even a surveying dog training game!

Presentation topics ranged from “Invasive Species Communication” to “Designing Public Programs,” plus a keynote presentation on “Climate-Smart Invasive Species Management and Policy” led by Bethany Bradley, Co-Director of the Northeast Climate Adaptation Science Center and Professor of Invasion Ecology & Biogeography at UMass-Amherst.

Partners offered some uniquely engaging tabling demonstrations like forest biodiversity Jenga (a huge hit!), native seed bomb making, spotted lanternfly vacuuming, and more.

We also had special guest, Stevie the NY-NJ Trail Conference Conservation Dog, help introduce the Volunteer Dog Surveyor Program, where volunteer handlers and pets sniff out invasive species.

Thank you to everyone who joined us and to CCE-Rockland for hosting!

Building community and resilient ecosystems! Earlier this month, our Invasives Strike Force Crew Leader, Griffin, and Program Manager, Ryan, enthusiastically participated in I Love My Park Day along the Old Croton Aqueduct. Together with a long list of partners, this day was carefully planned out in the weeks prior to amplify efforts where work has taken place at previous I Love My Park Day events. Dozens of individuals from local families, clubs, and organizations gathered to support Friends of the Old Croton Aqueduct’s Diane Alden and her vision to enhance healthy, native ecosystems along the trail.

Participants were divided into groups to focus on continuous sections; families and children pulled garlic mustard to their hearts' content while those with a bit more elbow grease focused on removing larger invasive shrubs. The Invasives Strike Force’s group pulled over 400 invasive plants and a whopping 24 pounds of garlic mustard! As usual, the event was a resounding success, combining community engagement with immediately visible results of trail and ecosystem improvement.

United by nature, driven by purpose: It’s , and we’re celebrating our incredible volunteers who power our work all year long! 🌿💚

We kicked things off last Saturday at our annual , where we championed our volunteer community and presented awards to the trail superheroes who go above and beyond. The sun was shining, the skies were bright, and the room radiated pure joy. ✨ Take a look at a few of the photos, and congrats to all our awardees!

Volunteers are the beating heart of the Trail Conference, driving our mission forward every day. Last year alone, more than 2,000 volunteers contributed 80,000+ hours across the region—painting blazes, restoring habitats, completing invasive species surveys, and maintaining miles of public pathways across the Northeast. 🥾🌲

And yet, volunteering is about more than just the tasks at hand. It’s a way to connect with nature and one another by caring for the outdoors together.

Irene Sheldon, a dedicated volunteer with our Stewardship Department and the 2026 recipient of the Joan Ehrenfeld Award for Responsible Stewardship, said it best:

“This isn’t just volunteering; it’s a job in the woods I absolutely love! Surveying invasive species for the Trail Conference is a joy thanks to the organization’s constant support, mentorship, and unwavering enthusiasm. I look forward to each new season!”

It’s volunteers like Irene, and supporters like you, who make protecting our shared trail lands possible. THANK YOU for all that you do! 🙌

🌍 Happy Earth Day! 🌿💙

Today, we celebrate the beauty and resilience of our planet—and commit to protecting it for generations to come! One way to safeguard natural spaces is by preventing the spread of invasive species. These plants and animals can disrupt ecosystems, but small actions make a BIG impact!

✨ Here’s how YOU can help: 🌱 Clean gear before & after hiking, paddling, or fishing. 🚫 Never release pets or plants into the wild. 🔎 Learn to identify & report invasive species to NY iMapInvasives. Get involved with the and our many partners!

Together, we can keep our parks, forests, and waterways thriving! 🌊🌳 Join the movement and make every day Earth Day! 🌎💪

Pine warblers flit as flickers fly overhead in a freshwater wetland tucked betwixt and between thunderous highway overpasses. You would never know you were in the heart of New York City while walking these wooded pathways - with birdsong replacing the endless thrum of city life. This thoughtfully restored area is one of many established and maintained by new Lower Hudson PRISM partner, Randall's Island Park Alliance (RIPA). We had the pleasure of touring this site, along with several other habitats RIPA stewards, including a saltwater marsh bustling with birds and fiddler crabs, an array of native and cultivated gardens, and an urban forest - all situated on this island between Manhattan, the Bronx, and Queens.

As a new partner, RIPA is excited to expand its knowledge on invasive species management and restoration techniques to benefit the many ecosystems this unique park is home to. We are so excited to have them join our partnership and cannot wait to see the work they accomplish in the coming seasons!
