Description:
This bog birch - leatherleaf shrub, moderately rich to poor fen is found in the northern Great Lakes region of the United States and Canada, and probably elsewhere. 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. The shrub cover is at least 25%, dominated by a combination of Betula pumila and ericaceous shrubs, including Andromeda polifolia, Chamaedaphne calyculata, Ledum groenlandicum, and Vaccinium oxycoccos. Other minerotrophic shrubs include Lonicera villosa, Rhamnus alnifolia, Rubus arcticus ssp. acaulis (= Rubus acaulis), Rubus pubescens, and Salix pedicellaris. Scattered, small (2-10 m) tree stems of Larix laricina, Picea mariana, and Thuja occidentalis are present at low cover. There is a diverse forb, graminoid, and moss cover, at least in the richer examples of this type. The graminoids include Carex chordorrhiza, Carex lasiocarpa, Carex leptalea, and Eriophorum viridicarinatum. Forbs include Drosera rotundifolia, Equisetum fluviatile, Maianthemum trifolium, Menyanthes trifoliata, Comarum palustre (= Potentilla palustris), Sarracenia purpurea, and Solidago uliginosa. The moss layer contains Aulacomnium palustre, Pleurozium schreberi, Sphagnum angustifolium, and Sphagnum capillifolium. Less frequent are Campylium stellatum, Sphagnum fuscum, and Tomentypnum nitens. Diagnostic features include the combination of Betula pumila and ericaceous shrubs in the shrub layer, and both minerotrophic and oligotrophic graminoid and forb species.
