Observation Narrative
Directions to plot and tree tag:
Follow ravine from where it intersects Otter? Creek. Plot is on north side, about ½ way upslope. Tagged tree is a Pinus strobus of60 cm dbh with tag #325. Conduit is at a bearing of_16_ degrees and _9.5 m from tree.
Plot location was pre-selected by the project's stratified random sampling design.
This is a rich community on fertile soil on a south-facing slope. The geology seems to be sandstone, but the species present on the slope (Asimina triloba, Celtis occidentalis, Cercis Canadensis, Ulmus rubra) suggest high calcium or magnesium content. Pinus strobus towers over most of the other trees.
