Observation Narrative
Plot is located on a rocky terrace with prairie inclusions, just below the confluence of Difficult Run and the Potomac River. Vegetation is a patchy shrubland of stunted trees with bedrock outcrops and grassy openings. The lower portion of the plot area was flooded this year. Species richness (110 taxa per 400 sq. m.) is very high.
