Name: Larix laricina / Chamaedaphne calyculata / Carex lasiocarpa Shrubland
Reference: Midwestern Ecology Working Group...
Description: This tamarack / ericaceous scrub poor fen is found in the northern Great Lakes region of the United States and into central Canada. Stands occur on peatlands with low exposure to minerotrophic groundwater including basin fens, shores above the level of the seasonal flooding, and larger peatlands. The water regime is saturated, and the substrate is fibric to mesic peat. The microtopography is low to intermediate hummocks with hollows. The vegetation is an open fen dominated by ericaceous shrubs, sedges, and <i>Sphagnum</i> spp. The scattered tree layer of <i>Larix laricina</i> and <i>Picea mariana</i> >2 m is less than 10%. The low-shrub layer is dominated by <i>Betula pumila, Chamaedaphne calyculata, Larix laricina, Salix discolor</i>, and <i>Salix pedicellaris</i>. The herb layer is somewhat low in diversity, with graminoids including the dominant <i>Carex lasiocarpa</i>, as well as <i>Carex chordorrhiza</i> and <i>Carex limosa</i>. <i>Carex oligosperma</i> may also occur. Forbs include <i>Sarracenia purpurea, Maianthemum trifolium</i>, and <i>Menyanthes trifoliata</i>. Mosses include <i>Sphagnum capillifolium, Sphagnum fuscum</i> and <i>Sphagnum magellanicum</i>. Diagnostic features include the ericaceous and tree scrub cover, the somewhat lower species diversity compared to richer fens, and <i>Carex lasiocarpa</i> more common than <i>Carex oligosperma</i>.
