Observation Narrative	This plot is located in a moderately large Shenandoah Valley sinkhole pond. The pond has three distinct environmental/vegetation zones: 1) open, deeply flooded center dominated by Nuphar advena; 2) slightly shallower margin dominated by Cephalanthus occidentalis and coarse graminoids; and 3) forested outer zone dominated by Acer rubrum, Nyssa sylvatica, Quercus palustris, and Carex barrattii. The plot captures vegetation of zone #2. Soils are deep mucky peats, recently exposed by draw-down of the water table. Sphagnum covers ca. 20% of the exposed soil surface.
