Observation Narrative
Plot captures diverse woodland vegetation on a rocky, frequently scoured shore along the Potomac River above Great Falls. Species richness is high, as is the cover and frequency of exotic weeds. Nevertheless, this is an apparently rare and recurrent vegetation type on high-gradient bedrock shores of the Potomac above the fall line.
