Observation Narrative
This open but nevertheless well-developed pine-oak/heath forest is notable for its scattered stems of Quercus marilandica, which abounds on Smith Mountain. Pine attains secondary importance to oak in this stand, and Pinus pungens is almost entirely absent, although it is more frequent in other stands on the flanks of this monadnock. A dense heath layer is co-dominated by Gaylussacia baccata and Vaccinium pallidum. Plot contains several large, steeply dipping (ca. 60 degrees), almost exfoliating boulders sparsely vegetated with graminoids.
0 - 2 - litter
2 - 12 - duff, thick in fine roots and partially decomposed organic matter (occasionally to 20+ cm deep)
12 - medium brown moist, silty clay loam; clay content and frequency of lenses of oxidized material increase with depth

Robust heath layer suggests the long absence of fire.
