Description:
This moderately rich shrub fen is found across the eastern boreal region of Canada and the adjacent U.S., including in the northern Great Lakes region. The shrub cover is at least 25%, dominated by a combination of <i>Betula pumila, Myrica gale</i>, and ericaceous shrubs, including low to moderate cover of <i>Andromeda polifolia, Chamaedaphne calyculata, Ledum groenlandicum</i>, and <i>Vaccinium oxycoccos</i>. Other minerotrophic shrubs include <i>Lonicera villosa, Rhamnus alnifolia, Rubus arcticus ssp. acaulis, Rubus pubescens</i>, and <i>Salix pedicellaris</i>. Scattered, small (2-10 m) tree stems of <i>Larix laricina, Picea mariana</i>, and <i>Thuja occidentalis</i> are present at low cover. There is diverse forb, graminoid, and moss cover, at least in the richer examples of this type. The graminoids include <i>Carex chordorrhiza, Carex lasiocarpa, Carex leptalea</i>, and <i>Eriophorum viridicarinatum</i>. Forbs include <i>Comarum palustre, Drosera rotundifolia, Equisetum fluviatile, Maianthemum trifolium, Menyanthes trifoliata, Sarracenia purpurea</i>, and <i>Solidago uliginosa</i>. The moss layer contains <i>Aulacomnium palustre, Pleurozium schreberi, Sphagnum angustifolium</i>, and <i>Sphagnum capillifolium</i>. Less frequent are <i>Campylium stellatum, Sphagnum fuscum</i>, and <i>Tomentypnum nitens</i>. Stands are found on the margins of water tracks of large peatlands, or in the interior of small basins that are relatively isolated from runoff, or on shores of northern and boreal rivers, with occasional flooding.
