Observation Narrative	Plot placed on a very steep, sheet-eroded ravine slope supporting a floristically depauperate hemlock - hardwood forest. Although adelgids are present, they have done relatively little damage to the hemlocks in this stand. Soil chemistry data indicate extremely acidic, infertile conditions that are inconsistent with the mapped geology (amphibolite) of this site.
