Observation Narrative	Plot positioned in the oldest part of a large eastern hemlock stand on a very steep, erosive bluff subtended by Bull Run. Continuous surface sheet-erosion apparently limits the establishment of woody seedlings and herbs. Tree recruitment is much denser on adjacent, convex or less steep parts of the bluff. Hardwoods, including Fagus grandifolia, Quercus montana, and Quercus alba, attain greater importance as overstory co-dominants elsewhere in the stand. Evidence of hemlock woolly adelgid is minimal at this site.
