Name: Juncus dichotomus Seasonally Flooded Herbaceous Alliance Reference: Eastern Ecology Working Group of... Description: This alliance encompasses rush-dominated vegetation of small, interdunal, very shallow, seasonally flooded basins. The 'dune swales' of the related Vaccinium macrocarpon Saturated Dwarf-shrubland Alliance (A.1094) (Sneddon et al. 1994) share some species with this alliance, such as Lycopodiella appressa, Utricularia subulata, and Drosera intermedia. However, sedges and rushes rather than Vaccinium macrocarpon are more characteristic of the Juncus dichotomus Seasonally Flooded Herbaceous Alliance (A.1427). Associates include Andropogon virginicus, Juncus dichotomus, Juncus canadensis, Juncus biflorus, Juncus scirpoides, Drosera intermedia, Fimbristylis autumnalis, Linum medium, Schoenoplectus pungens (= Scirpus pungens), and Solidago sempervirens. Soils are characterized by a shallow organic layer overlying sands. The water table is generally high (from 10-50 cm from the surface). This alliance occurs in close association, and often as part of a finely textured mosaic, with the III.A.2.N.i Morella cerifera Saturated Shrubland Alliance (A.1906) and the Morella (cerifera, pensylvanica) - Vaccinium formosum Seasonally Flooded Shrubland Alliance (A.1010) (which is not known from south of Maryland). Further data analysis will be required to establish the status and range of this alliance with greater confidence.  Accession Code: VB.CC.25211.JUNCUSDICHOTOMU Plot-observations of this Community Concept: 0
