East Gulf Coastal Plain Blackgum Dome SwampElement Identifiers NVCS association: Nyssa biflora / Ilex myrtifolia / Carex glaucescens - Eriocaulon compressum Forest Database Code: CEGL004720 Formation: Seasonally flooded cold-deciduous forest Alliance: NYSSA (AQUATICA, BIFLORA, OGECHE) POND SEASONALLY FLOODED FOREST ALLIANCE (I.B.2.N.e.9) Element Concept Summary: The canopy of this East Gulf Coastal Plain dome swamp community is strongly dominated by Nyssa biflora, often with scattered Taxodium ascendens, and sometimes low canopy height Ilex myrtifolia. The subcanopy is poorly developed, and consists of Ilex myrtifolia and Cyrilla parvifolia. Magnolia virginiana and Persea palustris may be present. Shrubs are typically not present or, at least, not abundant, but may include Lyonia lucida, Clethra alnifolia, Hypericum chapmanii, Hypericum brachyphyllum, Smilax laurifolia, and Smilax walteri. The herbaceous layer includes Eriocaulon compressum, Eriocaulon decangulare var. decangulare, Carex glaucescens, Lycopodiella alopecuroides, Coreopsis nudata, Juncus repens, Sabatia bartramii, Rhynchospora spp., Rhexia spp., Xyris spp., Woodwardia virginica, and Erigeron vernus. Tillandsia bartramii can be an abundant epiphyte. This association occurs in small seasonally to semipermanently flooded depressions surrounded by Pinus palustris - Pinus elliottii var. elliottii flatwoods. Fire periodically burns into the Nyssa ponds.

Swamp Tupelo Pond Forest (Allard 1990) B. in part Comments: Also see I.C.3.N.d for dome swamps with Pinus elliottii var. elliottii. Conservation Ranking & Rare Species GRank: G2G3 (97-06-19): Hydrologic alterations are the biggest threat to this type. Past ditching and draining have altered many examples. ORV traffic also poses a threat to vegetation and to the integrity of the hardpan underlying dome swamps. Fire is essential for the maintenance of a dome swamp community. Without periodic fires, hardwood invasion and peat accumulation can convert the swamp to bottomland forest or bog. Because these communities are typically wetter in the winter, burns during this time of year usually prove ineffective in maintaining this community.

It occurs in poorly developed sinkhole depressions in the Coastal Plain of Florida and Georgia, and is flooded long enough to preclude the presence of a significantly developed herb layer.
