Observation Narrative
This is the only Quercus montana-dominated oak/heath forest documented on Virginia's Eastern Shore to date. It constitutes a small portion of a relatively large patch of mostly deciduous "flatwoods" that is elsewhere better characterized as an acidic oak-hickory forest. The oak/heath stand occupies the steep slopes of a ravine and the high, sterile, convex upland at the top. Although no evidence of it was observed, this site is likely underlain by terrace gravels thrown up by the adjacent stream as it downcut its ravine millennia ago. The current stand probably regenerated from logging ca. 70 or 80 years ago; Pinus virginiana that regenerated with the oaks at that time is now decadent, dying, or dead. Quercus montana co-dominates with Q. velutina and Q. falcata in various size classes, with good regeneration present. Large Kalmia latifolia (15+ cm DBH) are prevalent on the steeper slopes, while deciduous ericads dominate the gentler upper slopes. No exotics or other disturbances were noted, excepting a very old road bed just west of the plot.
