Name: Carex lasiocarpa - Carex oligosperma - (Lysimachia terrestris) / Sphagnum spp. Acidic Peatland Reference: NatureServe Biotics 2019 Description: This graminoid poor fen community is found in the central midwestern region of the United States and extreme southern Canada. Stands occur south of the Laurentian region, in ice block or kettle-hole depressions on sand plains and till plains. They almost always occur in basins that have small watersheds, which minimizes runoff from surrounding uplands. They can also occur in areas with sandy, nutrient-poor soils. The water surface is mildly acidic with moderately low available nutrient concentrations. The surface mat is generally flat. The vegetation is dominated by graminoids, with up to 25% shrub cover, and scattered trees. The dominant graminoid is typically <i>Carex lasiocarpa</i>, and common associates or codominants include <i>Carex oligosperma, Carex utriculata, Carex haydenii, Eriophorum virginicum</i>, and <i>Scheuchzeria palustris</i>. Forbs include <i>Maianthemum trifolium</i> and <i>Sarracenia purpurea</i>. In central-southern Wisconsin, characteristic forbs include <i>Lysimachia terrestris</i> and <i>Hypericum kalmianum</i>. The moss layer is virtually continuous, and is dominated by <i>Sphagnum</i> spp. (including <i>Sphagnum recurvum</i>). The low-shrub layer varies from open to more dense, and may contain <i>Andromeda polifolia, Chamaedaphne calyculata, Kalmia polifolia, Vaccinium macrocarpon</i>, and <i>Vaccinium oxycoccos</i>. Taller shrubs or small trees are scattered and may include <i>Betula pumila, Larix laricina, Salix pedicellaris</i>, and <i>Spiraea tomentosa</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:34042-{D7E71928-64E4-4A07-90F4-BB6AEF7ED40C} Plot-observations of this Community Concept: 0
