Spartina patens - Festuca rubra Herbaceous Vegetation

Description:
This oligohaline to mesohaline marsh occurs as a narrow band at the border between high salt marsh and the adjacent uplands in northern New England. Salinity input is a result of irregular flooding by spring tides and storm surges with freshwater input from runoff or groundwater discharge. Substrate is peat that is drier than that of high salt marsh vegetation. Small pannes tend to form in this marsh; they can be rather temporary. Local dominants include Agrostis stolonifera, Juncus gerardii, and Spartina patens. Associated species include Symphyotrichum novi-belgii (= Aster novi-belgii), Solidago sempervirens, Festuca rubra, Spartina pectinata, and Schoenoplectus robustus. In wetter areas, Carex paleacea can be strongly dominant. In ponded, but less frequently flooded areas, Schoenoplectus tabernaemontani (= Scirpus tabernaemontani) and/or Juncus balticus var. littoralis (= Juncus arcticus var. littoralis) can be locally dominant. Species occurring less frequently can include Schoenoplectus pungens, Distichlis spicata, Triglochin maritima, Argentina anserina (= Potentilla anserina), Carex hormathodes, Ranunculus sceleratus, Panicum virgatum, Amaranthus cannabinus, Hierochloe odorata, Elymus virginicus, Teucrium canadense, Iris versicolor, Cuscuta gronovii, Impatiens capensis, Acorus calamus, Calystegia sepium, Typha angustifolia, Sanguisorba canadensis, and Phragmites australis. Local pannes can form within this marsh community with distinctly different species composition.
