Observation Narrative
Plot is located in a >5 acre boggy swale supporting an exceptionally large open seepage wetland. The major ecological conditions and processes influencing the vegetation are sandy, nutrient poor soils, abundant groundwater seepage and frequent incendiary fires from military training. Shrubs and tree saplings her appear to be burned back to the ground at least annually, allowing herbaceous, light demanding plants to prevail. Dominance and species distributions within the wetland are quite patchy. Therefore the plot area was made considerably larger than that usually sampled (100 sq. m.) in this type of vegetation.
Quantico Marine Base Impact Area, Range 15. In swale between road and stream, ca. 0.2 mi southeast of Davids Crossroads.
