Description:
This alliance, which is found in the eastern and southeastern United States, inhabits seasonally flooded marshes or emergent zones of upland depression ponds. The vegetation is dominated by ~Scirpus cyperinus$, or at least with substantial cover of this species. The habitat of this alliance may have a pronounced seasonal fluctuation in water level, becoming saturated to ponded in the winter and often drying completely in the summer. The vegetation is typically dominated by patches or zones of ~Scirpus cyperinus$; other species present may include ~Carex$ spp., ~Dichanthelium$ spp., ~Dulichium arundinaceum, Glyceria$ spp., ~Juncus$ spp., ~Leersia$ spp., ~Panicum rigidulum, Rhynchospora$ spp., and ~Thelypteris palustris$, as well as other species of ~Scirpus$ including ~Scirpus microcarpus (= Scirpus rubrotinctus)$ and ~Scirpus atrovirens$. The vegetation may consist of monospecific clumps of the component species, either scattered in the marsh or around the pond margin. Mats of ~Sphagnum$ mosses may be prominent in some examples (e.g., ~Sphagnum lescurii, Sphagnum pylaesii, Sphagnum cuspidatum, Sphagnum palustre$, and ~Sphagnum recurvum$. Some examples may have scattered woody plants, including shrubs and small trees such as ~Acer rubrum, Alnus serrulata, Cephalanthus occidentalis, Rosa palustris$, and ~Nyssa sylvatica$. To the north, ~Vaccinium corymbosum$ is a typical associate, while ~Hibiscus moscheutos, Itea virginica, Liquidambar styraciflua, Pinus taeda$, and ~Quercus phellos$ occur more frequently in the southern portion of the range. Sparsely distributed shrubs in montane examples may include ~Vaccinium$ spp. and ~Leucothoe racemosa$. The floristics and physiognomic expression may vary with context and management. In a burned or mowed context, examples of this vegetation type may grade down into other wetland herbaceous types, but in a more forested context may grade into upland depression forests.
