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 exclusively occupied 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 #1. Soils are deep mucky peats, still submerged even at this late date. An alga (probably Chara sp.) is abundantly submerged in this zone.
