Name: Betula glandulosa / Carex spp. Wet Shrubland
Reference: NatureServe Biotics 2019
Description: This association is found on the west side of Glacier National Park in Montana, and is also known from several low-elevation sites in Waterton Lakes National Park in Alberta. This association is found at 1135 to 1540 m (3720-5049 feet) elevation on basin floors. Sites are flat to gently inclined peatlands. Soils are organic (sedge peat), seasonally flooded to saturated, and very poorly drained. <i>Betula glandulosa</i> dominates the shrub canopy in all stands, with up to 70% cover. <i>Dasiphora fruticosa ssp. floribunda</i> and <i>Salix serissima</i> occur less frequently with less than 10% cover. <i>Salix drummondiana</i>, along with several other tall shrubs and short <i>Picea engelmannii</i>, occur with very low constancy. <i>Carex</i> species characterize the herbaceous understory, individually having between 20 and 60% constancy. The <i>Carex</i> species with the highest average cover are <i>Carex interior, Carex lasiocarpa, Carex limosa</i>, and <i>Carex aquatilis</i>. Stands can contain a moisture gradient with <i>Betula glandulosa</i> on slightly higher and better drained ground, with a <i>Carex lasiocarpa</i>-dominated fen or other <i>Carex</i> species in the lowest and wettest area. <i>Trichophorum cespitosum</i> is infrequent but can have high cover (55%). Forbs common in peatlands are usually present, such as <i>Menyanthes trifoliata, Comarum palustre</i>, and <i>Petasites frigidus var. sagittatus</i>. Most stands are shallowly flooded with an average moss and lichen cover of only 20%, while the drier stands have high ground cover of moss and lichens.
