Nature Detectives Hike

Great Swamp National Wildlife Refuge - Orange Trailhead approx 77 Meyersville Rd., Green Village (Harding Township), NJ, United States

What's hiding on the forest floor? What's going on in the trees? Let's do some detective work and make some discoveries together! The Great Swamp National Wildlife Refuge is the perfect place to learn how to identify animals from their tracks, scats (yes, poop) and other clues. Spy on secret hideouts used by birds, insects, and other woodland creatures. Discover the dining preferences of deer, raccoons, and even coyotes by putting a magnifying glass to some scat. All this detective work is easier than you think. And let’s face it, it’s fun being outdoors in the summer! Recommended for all, but especially children 5 to 12 years old accompanied by an adult. We will meet at the head of the Orange Trail at the end of Meyersville Rd., Green Village. The lot is small, so please consider carpooling and be mindful when parking. This event is free for our GSWA members. For non-members, a suggested $10 donation for adults and $5 for children 6-17 is appreciated.

Pre-Thanksgiving Day CMA Cleanup

Great Swamp Watershed Association's CMA 1 Tiger Lily Ln, Morristown, NJ, United States

This is a great opportunity to preemptively give back before Thanksgiving! We could use your help putting our 73-acre wetlands reserve to bed for the winter. At the Conservation Management Area (CMA) there's no shortage of things to accomplish on our honey-do list. We need to mulch and edge our trails, haul out old boardwalk lumber, clean up our seating areas, and more. A crisp, autumn morning is a fabulous time to get outside and get your hands dirty. We will provide you with all the tools you need to participate for as long as you like!
