Name: Carex oligosperma - Carex lasiocarpa Acidic Graminoid Bog & Fen Alliance
Reference: NatureServe Biotics 2019
Description: This alliance, found in eastern boreal Canada and north-central and northeastern United States, is composed of weakly minerotrophic peatlands dominated by graminoids. <i>Carex lasiocarpa</i> and <i>Carex oligosperma</i> are typically dominant. Associated species include <i>Carex chordorrhiza, Eriophorum</i> spp., <i>Rhynchospora alba, Scheuchzeria palustris</i>, and <i>Trichophorum cespitosum</i>. <i>Sphagnum</i> spp. form a moderate to nearly continuous ground cover. Shrubs and small trees are common. <i>Betula pumila, Chamaedaphne calyculata, Larix laricina, Ledum groenlandicum, Picea mariana</i>, and <i>Salix</i> spp. are the most abundant. Stands are found in depressions on deep peat (&gt;1 m) that receives minimal nutrient-rich runoff from surrounding uplands. The surface water is slightly to strongly acidic (typically pH is &lt;5.5). The microtopography consists of low to intermediate hummocks and hollows.
