Moss and Lichens of the PNW

If you’ve explored anywhere in the Portland area, you’ve probably noted how green it is. The trees and the ferns provide much of the green, but so do the lichens and moss. Join instructor Ruth Williams as she takes you on a walking exploration of the most common tiny green wonders you will see on local trails. Learn what makes each of them unique and how to identify common species. This event is corrdinated by Hoyt Arboretum, and registration is required through their website.
