Name: Calamagrostis canadensis - Carex viridula - Cladium mariscoides - Lobelia kalmii Herbaceous Vegetation Reference: Midwestern Ecology Working Group... Description: This community is typically found on marly coastal sites in northern Lake Michigan, Lake Huron, and Lake Superior in the United States. These sites occupy embayments of open, sandy shorelines where limestone bedrock or cobble is at or near the surface. These sites have calcareous soils (with a pH as high as 8.2), resulting either from calcareous substrates, waterflow off adjacent limestone bedrock or limestone-rich till, or algal precipitation of calcium carbonate in the relatively warm, carbonate-saturated waters. These 'marly flats' contain a rich assemblage of calciphilic plants. Herbaceous species dominate parts of these areas. The dominant graminoid is Calamagrostis canadensis, but Carex viridula and Lobelia kalmii are key diagnostics of this type. Other diagnostic species include Cladium mariscoides, Hypericum kalmianum, Dichanthelium acuminatum var. lindheimeri (= Panicum lindheimeri), Argentina anserina (= Potentilla anserina), and Triglochin maritima. Scattered shrubs, such as Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda) or Myrica gale may be present, but shrub cover is less than 25%. In Wisconsin, in coastal estuaries of Lake Superior, common associates include Cladium mariscoides, Carex livida, and Triglochin maritima. Carex exilis is codominant at several sites. On Isle Royale, sedges dominate the vegetation. Cladium mariscoides is most abundant; other common herbs include Carex lacustris, Rhynchospora alba, and Utricularia intermedia. Myrica gale is the most abundant shrub. Sphagnum spp. form an incomplete cover.  Accession Code: VB.CC.25446.CALAMAGROSTISCA Plot-observations of this Community Concept: 0
