Observation Narrative ? Thinly wooded area at west end of a large cliff on slope flanking the upper part of Field Hollow. The sampling site encompasses two ledges separated by a near-vertical face approximately 1.5 m high. This area transitions to the east into more open cliff vegetation of similar composition. Moss mats and thin pockets of colluvium support most of the vascular plants in the plot. The putatively exotic grass Poa compressa is one of the most abundant herbs. Some Alliaria petiolata has invaded the deepest colluvium on the lower ledge.
