Observation Narrative
The habitat is a large quartzite talus/stone field. Deeply piled rocks and xeric conditions greatly limit species richness and diversity. No herbaceous species occur in the plot and dominant black birches are highly gnarled.
Plot location: Shenandoah NP: Boulderfield ca. 35 meters west of Austin Mountain Trail, ca. 0.15 miles north of its jct. with the Trayfoot Mountain Trail.
