Observation Narrative
Sample site is a relatively high, sandy, depositional bar along the Potomac River below Chain Bridge. It is located at a slightly higher elevation than the channel-shelf boulder bar sampled in GWMP009, and is adjacent to a disturbed, historically quarried slope now covered in exotic vegetation. Large, coarse forbs dominate the vegetation and exotics weeds, especially Datura stramonium and Artemisia annua, are abundant. This stand is very characteristic of vegetation occupying well-drained, sandy bars in the Potomac Gorge.
