Observation Narrative
Directions to plot and tree tag:
Tree is about 70m E of BR Parkway, just NW of Humpback Rocks Picnic Area. Tagged tree is a Quercus rubra of 55 cm dbh with tag #493. Conduit is at a bearing of 278 degrees and 4.4 m from tree.
Plot location was pre-selected by the project's stratified random sampling design.
This is an oak-hickory forest in which many large trees have died due to gypsy moths. The shrub layer is very dense everywhere except for the seepy area at the center of the plot. The herb layer is very dense and rich in the seepy area.
