Observation Narrative
Very dry outcrop habitat on bedrock terrace along, and approximately 12 m in elevation, above the Potomac River. The habitat is periodically scoured by large floods (~7 to 12 year return interval). Vascular vegetation is sparse. Lichens, especially Xanthoparmelia cf. conspersa, Dimelaena oreana, and various crustose species, are dominant over most of the plot. Several small pools are present.
