Observation Narrative	Plot location: crest of east ridge of Bull Run Mountain, 1.29 km NE of Beverly Mill. Marked with a metal tree tag. See form/report for sketch. Rock types present: no surface rocks present. This plot is similar to BULL050P but is located on a sub-level crest and has many fewer pines. The open Quercus montana-dominated forest has very low species-richness and nearly lacks herbaceous plants because of poor, dry, densely humus-mantled soils and intense competition from colonial ericads. Among the latter, Gaylussacia baccata is the prevalent species, with Kalmia latifolia and Vaccinium pallidum also common. Judging from the number of charcoal fragments unearthed while collecting soil samples, past fires on this ridge were frequent and/or large.
