Observation Narrative
Plot location: Along a branch 0.5 miles SSW of Pleasant Valley Church and 0.9 miles WSW of junction Blackwater Road and Head of River Road. Plot center is a double ash tree flagged at 1.8m.
This plot is situated ca. 0.3 miles upstream of plot NLAR027 on the same headbranch, and lies entirely above the limits of wind-tidal flooding. The swamp forest here is dominated almost exclusively by Fraxinus pennsylvanica, with Nyssa biflora and Taxodium distichum virtually absent from the stand. The reasons for this compositional change are not entirely clear, but may include differences in substrate, hydrology, and/or disturbance history.
