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 Salix arctica-dominated dwarf-shrublands. The lush dwarf-shrub layer averages 70% cover and is dominated by Salix reticulata. Salix rotundifolia ssp. dodgeana or Salix arctica may be common also. The herbaceous layer is dominated by the perennial forb Caltha leptosepala, which averages 22% cover and 100% consistency. Several other forbs are present with lower consistency and cover. Silene acaulis was the only other forb with over 10% cover. There is also a sparse graminoid layer (>20% cover) composed of Carex haydenii and Poa alpina (the most consistent species) and Carex nova, Carex scirpoidea, Deschampsia caespitosa, and Luzula spicata, all with at least 5% average canopy cover. Diagnostic of this alpine wetland is the dominance of the dwarf-shrub Salix reticulata and the forb Caltha leptosepala.  Accession Code: VB.CC.25502.SALIXRETICULATA Plot-observations of this Community Concept: 0
