CEGL004653 Taxodium distichum / Cephalanthus occidentalis / Juncus repens Swamp Woodland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Bald-cypress / Common Buttonbush / Lesser Creeping Rush Swamp Woodland

Colloquial Name: Lake Drummond Pondshore

Hierarchy Level:  Association

Type Concept: This community occurs on the sandy and peaty, seasonally flooded shores of Lake Drummond (Great Dismal Swamp National Wildlife Refuge) and Outer Coastal Plain vernal ponds in Virginia. Taxodium distichum forms an open canopy (averaging about 50% cover). The shrub stratum is dominated by Cephalanthus occidentalis and seedlings of Taxodium distichum, with Clethra alnifolia, Eubotrys racemosa, Toxicodendron radicans ssp. radicans, and Acer rubrum also present. Herbaceous species typical of forested swamps, such as Triadenum walteri, Bidens discoidea, and Cuscuta compacta, occupy the peaty bases of trees and shrubs. Larger areas of exposed sand support Juncus repens, Eleocharis quadrangulata, Panicum verrucosum, Fuirena pumila, Cyperus polystachyos var. texensis, Cyperus odoratus, Fimbristylis autumnalis, Lindernia dubia, Echinochloa muricata, and Panicum dichotomiflorum.

Classification Comments: This association was originally described from Lake Drummond, Virginia, at Great Dismal Swamp NWR and has since been found at other seasonally flooded basin ponds of the Outer Coastal Plain of Virginia (G.P. Fleming pers. comm. 2005). It is related to ~Taxodium distichum - Taxodium ascendens / Panicum hemitomon Swamp Woodland (CEGL004466)$$ which is found along the shorelines of blackwater lakes in North Carolina. Merger of these types was considered in January 2005 and decided against because of the following perceived floristic differences. Taxodium ascendens does not occur in Virginia, and Panicum hemitomon and Cyrilla racemiflora do not occur in pond or lakeshore habitats there (G.P. Fleming pers. comm. 2004). Though the Taxodium species is ambiguous and the tree base herbs are similar, CEGL004466 does not have Cephalanthus occidentalis, and Panicum hemitomon and Cyrilla racemiflora are pretty important components of it.
