Name:
Spartina patens - Eleocharis parvula Marsh
Reference:
NatureServe Biotics 2019
Description:
This brackish, interdunal swale and overwash community of the northeastern Atlantic Coast occurs in low areas behind primary or secondary sand dunes. The substrate is sand with little or no organic accumulation. The water source for this wetland community is variable, including seasonally high groundwater table, salt spray, and sporadic tidal overwash, resulting in widely variable salinity levels. The dominant species is generally <i>Spartina patens</i>, but it can be <i>Eleocharis parvula, Schoenoplectus pungens, Cyperus polystachyos</i>, and/or <i>Juncus articulatus</i>. Associated species depend on salinity and hydrology and can include <i>Leptochloa fusca ssp. fascicularis, Bolboschoenus maritimus, Bolboschoenus robustus, Mikania scandens, Juncus ambiguus, Juncus scirpoides, Ptilimnium capillaceum, Rumex maritimus, Symphyotrichum subulatum, Chenopodium rubrum, Pluchea odorata, Hibiscus moscheutos, Polygonum ramosissimum, Triglochin maritima, Panicum virgatum, Bolboschoenus robustus</i>, and <i>Argentina anserina</i>. <i>Iva frutescens</i> and <i>Baccharis halimifolia</i> may occur on hummocks within the swale. Mats of blue-green and/or brown algae can proliferate across the soil surface.
