Observation Narrative
Directions to plot and tree tag:
Park at "wormy chestnut" shop. Walk on road toward quarry ~130m. Take slope NW up to ridgeline. Stand is on spine of ridge just before it begins to ascend steeply to the summit. Tagged tree is flagged pink. Tagged tree is a Quercus rubra of 43 cm dbh with tag #170. Conduit is at a bearing of 80 degrees and 4.5 m from tree.
Plot location was selected in the field by DNH Ecologists, targeting area of ultramafic geology.
Sample targets small area of ultramafic geology near park boundary and adjacent to quarry. Top of W-tending side ridge. Mostly dominated by Carya ovata with red oak, white oak, chestnut oak, outcroppings of flaggy olivine (?). Approximately 15m E of plot, where ridge rises, more massive rock starts (mapped as amphibolite).
