Observation Narrative
This sample is located in the same stand as SURR006 but is located on a flat adjacent to the main channel of the Blackwater River. More light penetrates the tree canopy here and patches of exposed sandy alluvial support an abundance of draw-down herbs. The occurrence of the state-rare plant Mitreola petiolata is noteworthy.
