Half of this plot is composed of a recently thinned A. amabils and T. heterophylla pole sized forest that is open. The other half is composed of very dense T. heterophylla regeneration with occasional P. menziesii of pole size and small log size projecting above. There are also a few A. rubrus within the dense T. heterophylla and a few T. plicta of pole size distributed around the whole plot. There are many carpet mosses. The dominant lichens in the open forest are dominated by P. glauca and H. apinnata, with significant populations of P. stenophylla and P. herrei. The dense T. heterophylla was pretty much void of lichens, though there was more H. tubulosa to the north of the plot. The P. menziesii and T. heterophylla that project above the T. heterophylla dense regen. yielded the only S. globosus and very long Usnea sp.. Slope 14%. Aspect 338°. Abundance code: 3; Seen only in dense Tsuga heterophylla regrowth. Substrate: TSHE br.
