Name: A.1427
Reference: EcoArt 2002
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)$$ and the III.B.2.N.e ~~Morella (cerifera, pensylvanica) - Vaccinium formosum$ Shrubland Alliance (A.1010)$$ (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.
