Plant for Pollinators Webinar #4: The Extraordinary Caterpillar – Nature’s Tiniest Superhero!

Stream Assessment Training – FREE

Summit Free Public Library 75 Maple Street, Summit, NJ

Unless there's obvious pollution in the river or stream, to the untrained eye, the water may look healthy. But is it? This free training session, led by Sandra LaVigne, GSWA Director of Water Quality Programs, will provide you with all the necessary skills to make your own determinations. An indoor classroom session teaches you how to conduct visual and biological stream assessments, identify macroinvertebrates, and recognize environmental factors that could impact stream health. An outdoor session lets you practice your new-found skills at a local stream site. By afternoon, you will be fully trained in visual and biological stream assessment. And if you are ready to take that next step, consider becoming a stream monitoring volunteer! Tools and supplies will be provided. It gets a little messy so wear your boots and bring clean shoes to change into afterward. Preferred volunteers are 15 or older. This free training session is held in conjunction with the AmeriCorps New Jersey Watershed Ambassador Program.

Full Moon Hike at the Refuge

Blue Moon Hike at the Refuge

Great Swamp National Wildlife Refuge - Bluebird Parking Lot Bluebird Parking Lot, Great Swamp National Wildlife Refuge, NJ, United States

Experience the Great Swamp like never before under the rare glow of a Blue Moon. While the moon won't actually change color, this celestial event occurs when a single calendar month—in this case, May 2026—features two full moons instead of one. Because the lunar cycle is approximately 29.5 days, the timing occasionally "laps" our 31-day months, giving us a "bonus" full moon that only appears once every two to three years. We’ll explore the vibrant nocturnal world of the swamp—listening for the chorus of cicadas and spring peepers, watching for the silhouettes of owls, and soaking in the serene atmosphere of the marsh after dark. It’s a unique opportunity to connect with the watershed during a truly "once in a blue moon" moment. Be sure to wear appropriate footwear, dress for the weather, and bring a reusable water bottle and snacks if you so choose. Registration is required. IMPORTANT -- WAIVER: Per our special use permit, the refuge is asking for the hike participants to fill out a liability form before attending. Please complete and email this form to [email protected] when you register for this hike.  Please email Izzy ([email protected]) with questions or cancellations. Ticket sales end on 3/2/2026 at […]
