Name: Salix arctica - Salix petrophila / Caltha leptosepala Dwarf-shrubland
Reference: Western Ecology Working Group of...
Description: This mesic alpine dwarf-shrubland is found at 2800 to 3050 m (9200-10,000 feet) elevation in ranges of the Intermountain Basin of northern Nevada and in the Rocky Mountains of western Wyoming. Sites are on gentle, northerly slopes. It is found on mesic sites and is one of the wettest associations in ~<i>Salix arctica - Salix nivalis - Salix reticulata</i> Dwarf-shrubland Alliance (A3176)$$. The dwarf-shrub is creeping along the ground and is rarely taller than 12.7-20.3 cm (5-8 inches), forming the dwarf-shrub layer. Snowmelt keeps the site wet to saturated for much of the growing season. The vegetation is characterized by the dominance of the dwarf-shrub <i>Salix arctica</i> or <i>Salix petrophila (= Salix arctica ssp. petraea)</i>, sometimes with <i>Salix reticulata</i> and with <i>Caltha leptosepala</i> as a dominant forb. Other common species include <i>Antennaria</i> spp., <i>Astragalus alpinus, Carex elynoides, Erigeron peregrinus, Gentiana calycosa, Festuca brachyphylla, Packera dimorphophylla, Pedicularis groenlandica, Polygonum bistortoides, Ranunculus eschscholtzii, Sibbaldia procumbens</i>, and <i>Senecio crassulus</i>.
