Name:
Carex lasiocarpa - Calamagrostis spp. - (Eleocharis rostellata) Herbaceous Vegetation
Reference:
Midwestern Ecology Working Group...
Description:
This rich graminoid fen community type is found in the midwestern prairie and prairie-forest border region of the United States. Stands are found on wet, saturated soils (but not seepage) with groundwater influence, or on lake margins and/or grounded or floating mats. Peat depths may be less than 0.5 m, and stands may be on shallow, highly decomposed sedge peat, or rarely on wet, mineral soil. Sphagnum spp. are typically absent. The graminoid layer is often dominated by Carex lasiocarpa, with associates of Carex aquatilis, Carex buxbaumii, Carex interior, Carex livida, Carex pellita, Carex sartwellii, Carex stricta, Decodon verticillatus, Dulichium arundinaceum, Eleocharis elliptica, Eleocharis palustris (= Eleocharis smallii), Eriophorum angustifolium, Glyceria grandis, Schoenoplectus acutus (= Scirpus acutus), and Schoenoplectus subterminalis (= Scirpus subterminalis). Eleocharis rostellata and Cladium mariscoides occur less frequently. Grasses include Calamagrostis canadensis and Calamagrostis stricta. Prairie and other herbs are present, such as Cardamine pratensis, Comarum palustre (= Potentilla palustris), Euthamia graminifolia, Galium labradoricum, Impatiens capensis, Lobelia kalmii, Lycopus uniflorus, Lysimachia thyrsiflora, Menyanthes trifoliata, Pedicularis lanceolata, and Triadenum fraseri. Brown mosses may include Leptodictyum riparium (= Amblystegium riparium), Calliergonella cuspidata, Campylium polygamum, Campylium stellatum, and Fissidens adianthoides. Shrub cover is variable and may exceed 25%. Betula pumila, Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda), Salix candida, Salix pedicellaris, and Spiraea tomentosa may be present. A more marly beach fen subtype is found in Indiana, and contains a combination of prairie and alkaline fen indicators. Western Ohio stands lack some of the more boreal species.
