| Landscape Narrative |
Across channel is an island with an extensive floodplain forest. Slightly higher elevation on channel shelf rapidly grades to more xeric herb communities dominated by Apocynum cannabinum and, higher up, Solidago gigantea.;Back channel shelf behind large island in the Shendoah River. This section is where it flows over phyllite ledges which forms a rapids zone. Community is an emergent herb zone with a near monoculture of Justicia americana which grows in patches here where it can "keep its feet wet," along flowing channels and standing pools, in bedrock cracks and gravel in the water. There is one battered Platanus occidentalis and one Fraxinus pensylvanica in the community.

| Representativeness |
Long, narrow plot captures community type on one side of a large flowing back channel. As usual, this is a near monoculture of Justicia americana with additional species representing microsites. This is an unusual occurrence because it is on bedrock rathe
