Name:
Carex lasiocarpa - Carex oligosperma / Sphagnum spp. Herbaceous Vegetation
Reference:
Midwestern Ecology Working Group...
Description:
This graminoid poor fen community is found in the Great Lakes region of the United States and Canada, as well as elsewhere in central Canada. Stands are found in peatlands with low exposure to mineral-rich groundwater, including basin fens, shores above the level of seasonal flooding and larger peatlands. Water hydrology is saturated, and surface water is slightly acidic and nutrient poor. The vegetation is dominated by graminoids, with up to 25% shrub cover, and scattered trees. The dominant graminoid is Carex lasiocarpa, and typical associates include Carex chordorrhiza, Carex limosa, Carex oligosperma, Rhynchospora alba, Trichophorum caespitosum (= Scirpus cespitosus), and Scheuchzeria palustris. Forbs include Arethusa bulbosa, Symphyotrichum boreale (= Aster borealis), Calopogon tuberosus, Pogonia ophioglossoides, Sarracenia purpurea, and Solidago uliginosa. The low-shrub layer contains Andromeda polifolia, Betula pumila, Chamaedaphne calyculata, Larix laricina, Salix discolor, Salix pedicellaris, and Vaccinium oxycoccos. The moss layer is virtually continuous, and is dominated by Sphagnum capillifolium, Sphagnum fuscum, and Sphagnum magellanicum. Diagnostic features include the dominance of graminoids, particularly Carex lasiocarpa, the almost continuous layer of Sphagnum peat, and few minerotrophic indicators.
