Andrienne Kovasi and I will be leading the annual lichen walk at Mt. Pisgah Arboretum Jan 18, 2020, 10:00-12:00. Meet at the Visitors Center below the parking lots. We will mosey along through riparian oaks then climb slowly through a Doug-fir forest, then along the edge of the oak savannah, ending up at the silo to look at the amazing Chaenotheca population there. The walk happens in rain or shine.
