Name:
Salix glauca Wet Shrubland
Reference:
NatureServe Biotics 2019
Description:
This cold-deciduous, mesic, subalpine shrubland occurs on moderate to steep slopes at elevations between 1770 and 3000 m (5800-9900 feet), in areas of snow catchment, fluvial and colluvial landforms, talus and scree in avalanche paths. Stands are mesic and can be temporarily flooded by seasonal runoff. Soils are thin, poorly developed and well-drained with or without calcareous sandstone gravels. Stands can occur as a uniform shrubland or, in the alpine, within ribbons that alternate with talus and scree. Stands are dominated by <i>Salix glauca</i> with 25-60% cover. Co-occurring shrub species are highly variable. In Glacier National Park, <i>Spiraea betulifolia, Amelanchier alnifolia, Penstemon fruticosus, Dasiphora fruticosa ssp. floribunda, Symphoricarpos occidentalis</i>, and <i>Arctostaphylos uva-ursi</i> can be present with 5-15% cover. <i>Abies lasiocarpa</i> seedlings may also be present in the shrub layer with low cover. In southeastern Montana and in Grand Teton National Park, stands had no other shrubs present. Graminoid cover is low (1-15%) with <i>Festuca campestris, Bromus inermis, Poa alpina, Trisetum spicatum</i>, or <i>Elymus trachycaulus</i>. Forb cover can be low to high with several species combined contributing 10-60%. Species present may include <i>Aquilegia flavescens, Hedysarum sulphurescens, Heracleum maximum, Thalictrum occidentale, Anemone multifida, Antennaria umbrinella, Arenaria congesta, Erigeron</i> sp., <i>Potentilla gracilis, Chamerion angustifolium, Oreostemma alpigenum, Castilleja miniata, Clematis occidentalis, Valeriana sitchensis</i>, and <i>Synthyris pinnatifida</i>.
