Observation Narrative	Tsuga canadensis dominates the overstory along this very steep and treacherous slope above Chopawamsic Creek. No plot was laid out due to very steep slope and active erosion. The releve area surveyed approximates 5-6 ares; cover estimates must be treated with caution. Many Tsuga individuals have narrow, poorly developed crowns with abundant dead lower branches, but this stand is otherwise in excellent condition and may have persisted large free from anthropogenic disturbance for three centuries or more. One tree was aged at 300+ years; an increment core was very difficult to read, and multiple examinations yielded a range of 280-330, so this estimate may be conservative. No regeneration of Tsuga is evident, however. There is no evidence of infestation by hemlock woolly adelgid. Parent material exhibits even steeper bedding plane than the slope and is actively exfoliating. Ground cover is sparse owing to slope declination, thinness of soil, and abundance of outcrops. At crest of ridge vegetation grades into stand dominated by Quercus and Carya spp., and some of the larger oaks on the edge of the slope contribute cover in the area sampled. Seepage along outcrops and the sheltered condition of slope provide a suitable microhabitat for pteridophytes. No soil sample was collected and trees were not measured. Directions to plot: Follow gravel road along Chopawamsic Creek from Russell Road. Park just before fifth crossing of creek and follow creek upstream. Tsuga canadensis dominates the steep NW-facing slope above the creek for ca. 100 m.
