Ready for the first guided nocturnal invertebrate treasure hunt of the year? Join Docent Naturalists Debbi Brusco, Jack Owicki, Vivian Neou, and Ray Curiel on this moderately-paced meander along the Spring Ridge and Betsy Crowder trails with extended stops to observe smaller wildlife and their signs. Once it gets dark, you'll listen for night creatures and try to identify who you’re hearing. This activity is geared toward adults but attentive children ten years and older are welcome. Bring snacks for a brief break and a flashlight that has a red light or red filter if you have it. Reservations are required and will be accepted on or after March 27 at 12:00 p.m. (Noon) and close April 9 at 2:00 p.m.
