Event Description

One of RBG’s Courses & Workshops

This beginner level workshop is for trail-walkers eager to learn to identify the trees they most frequently encounter. Led by Nadia Cavallin, we’ll get to know 10 trees by name, learn about the wonders of their natural history, and discover the basics of using a botanical key so you can continue IDing new trees on your own. Inclement weather date: July 17.

Fee: $25 + Service Fee.

(Members 10% off*)
Please pre-register before July 6*
