Observation Narrative
Directions to plot and tree tag:
Tree is about 25m from BR Parkway on a NW bearing. Tagged tree is a Quercus rubra of 38 cm dbh with tag #314. Conduit is at a bearing of 312 degrees and 4 m from tree.
Plot location was pre-selected by the project's stratified random sampling design.
This is a mixed softwood-hardwood community with extensive cover of heaths and almost no herbs. The pines are the largest trees (>40cm dbh) and there are a few large oaks like the witness tree, but many of the trees are just barely trees.
