CEGL004655 Taxodium distichum / Zizania aquatica - Carex canescens ssp. disjuncta Tidal Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bald-cypress / Annual Wild Rice - Silvery Sedge Tidal Woodland
Colloquial Name: Mid-Atlantic Tidal Bald-cypress Woodland
Hierarchy Level: Association
Type Concept: This community is known from the Northwest River, Virginia. It occurs on oligotrophic, somewhat quaking peat at the upland edge of an extensive low marsh, where frequently flooded by wind tides. It retains standing water for most of the growing season and may receive groundwater seepage from adjacent uplands. Fire may also be important in the maintenance of this community. Taxodium distichum forms an open, stunted canopy. Shrubs dominate the upland edge, and are dominated by Morella cerifera, Clethra alnifolia, Lyonia ligustrina var. foliosiflora, and Toxicodendron radicans ssp. radicans. Away from the upland edge, Eleocharis rostellata, Eleocharis fallax, and Carex canescens ssp. disjuncta are the spring dominants. By late summer, Zizania aquatica and Eryngium aquaticum var. aquaticum are the aspect dominants. Other noteworthy herbaceous species include Cladium mariscoides, Rhynchospora glomerata, Nymphaea odorata, Pogonia ophioglossoides, Eriocaulon decangulare var. decangulare, Coreopsis falcata, Asclepias lanceolata, and Physostegia leptophylla.
