Name: Salix reticulata / Caltha leptosepala Dwarf-shrubland Reference: Western Ecology Working Group of... Description: This wetland association has been documented from the alpine of three mountain ranges in southwestern Montana. Elevations range from 2950-3090 m. This minor community has been described exclusively from north-facing slopes, which are uncommon in the north/south-trending ranges where it is found. The three known sites are on gentle to steep, soil-mantled solifluction slopes that are subirrigated by late-persisting snowfields lying above. The typically clay soils are low in coarse fragment content (<10%) and derived from limestone parent materials. Stands are unevenly distributed, and seemingly appropriate habitats are often occupied by <i>Salix arctica</i>-dominated dwarf-shrublands. The lush dwarf-shrub layer averages 70% cover and is dominated by <i>Salix reticulata</i>. <i>Salix rotundifolia ssp. dodgeana</i> or <i>Salix arctica</i> may be common also. The herbaceous layer is dominated by the perennial forb <i>Caltha leptosepala</i>, which averages 22% cover and 100% consistency. Several other forbs are present with lower consistency and cover. <i>Silene acaulis</i> was the only other forb with over 10% cover. There is also a sparse graminoid layer (>20% cover) composed of <i>Carex haydenii</i> and <i>Poa alpina</i> (the most consistent species) and <i>Carex nova, Carex scirpoidea, Deschampsia caespitosa</i>, and <i>Luzula spicata</i>, all with at least 5% average canopy cover. Diagnostic of this alpine wetland is the dominance of the dwarf-shrub <i>Salix reticulata</i> and the forb <i>Caltha leptosepala</i>.  Accession Code: VB.CC.32549.CEGL001435 Plot-observations of this Community Concept: 0
