This is a N-facing old growth ABGR stand with no sign of disturbance other than abundant sheep and bear trails. It is moderately steep but the convex slop , vegetation and trails make travel mostly easy. Understory vegetation is diverse. The downslope portion lacks trees and is mostly Acer glabrum, Alnus incana and Sorbus sp. Upper plot has small rock outcrop. Abundance code: 4.6; isidia > lobulate, young isidia conical, may be some M. exasperatula mixed in ; The site is obviously clean because hardwoods are old enough to host lichens but lack nitrophytes. Things like Usnea and Parmelia could be seen on 1 to 2 upper maples, but could not be reached. Conifer boles have a limited nuber of species: mostly LETVUL,. Substrate: ABGR br. Phenology: isidia.
