CEGL004975 Quercus lyrata / Betula nigra / Pleopeltis polypodioides ssp. michauxiana Pond Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Overcup Oak / River Birch / Resurrection Fern Pond Forest
Colloquial Name: Sinking Pond Overcup Oak Swamp Forest
Hierarchy Level: Association
Type Concept: This forest is found in an apparently unique isolated upland depression of the Eastern Highland Rim of Tennessee. The only example of this seasonally flooded forest community is known from Sinking Pond, Coffee County, Tennessee; it is inundated for 6 months of the year in winter and spring. The water may be up to 4.5 m deep at its greatest depth. Soils are Fragiaquults of the Guthrie series. In areas of 1 m or greater depth, Quercus lyrata (up to 130 cm dbh) forms a nearly single-species community. In shallower areas other species may be found; these include Quercus phellos, Liquidambar styraciflua, Nyssa aquatica, Nyssa biflora, Betula nigra, Acer rubrum, Cephalanthus occidentalis, Styrax americanus, Aronia arbutifolia, and Campsis radicans. No herbaceous ground layer exists. Mosses, lichens and epiphytic Pleopeltis polypodioides ssp. michauxiana can often be found on tree trunks.

Floristics: In areas of 1 m or greater depth, Quercus lyrata (up to 130 cm dbh) forms a nearly single-species community. This species is adapted to the seasonally deeper water, and these adaptations give it a competitive advantage (Wolfe 1996). In shallower areas other species may be found; these include Quercus phellos, Liquidambar styraciflua, Nyssa aquatica, Nyssa biflora, Betula nigra, Acer rubrum, Cephalanthus occidentalis, Styrax americanus, Aronia arbutifolia, and Campsis radicans. No herbaceous ground layer exists. Mosses, lichens and epiphytic Pleopeltis polypodioides ssp. michauxiana can often be found on tree trunks.

Environmental Description: This vegetation occurs in Sinking Pond, a compound sink in the karst landscape of the Barrens of Coffee County, Tennessee (Wolfe 1996). This seasonally flooded forest is inundated for six months of the year in winter and spring. The water may be up to 4.5 meters deep at its greatest depth. Soils are Fragiaquults of the Guthrie series. The water level in Sinking Pond has been measured to rise 2 m in less than 24 hours (Wolfe 1996).
Geographic Range: This association is restricted to the karst landscape of the Barrens of Coffee County, Tennessee (Interior Low Plateau).
