Salix glauca Shrubland
Reference:
Western Ecology Working Group of...
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 well-drained Regosolics, with or without calcareous sandstone gravels. Stands can occur as a uniform shrubland or within ribbons that alternate with talus and scree. Stands are dominated Salix glauca with 25-60% cover. Co-occurring shrub species are highly variable. In Glacier National Park, Spiraea betulifolia, Amelanchier alnifolia, Penstemon fruticosus, Dasiphora fruticosa ssp. floribunda, Symphoricarpos occidentalis, and Arctostaphylos uva-ursi can be present with 5-15% cover. Abies lasiocarpa seedlings may also be present in the shrub layer with low cover. In southeastern Montana, stands had no other shrubs present. Graminoid cover is low (1-15%) with Festuca campestris, Bromus inermis, Poa alpina, or Elymus caninus (= Agropyron caninum). Forb cover can be high with several species combined contributing to the high cover of 30-60%. Species present may include Aquilegia flavescens, Hedysarum sulphurescens, Heracleum maximum, Thalictrum occidentale, Anemone multifida, Chamerion angustifolium, Oreostemma alpigenum (= Aster alpigenus), Castilleja miniata, Clematis occidentalis, Valeriana sitchensis, and Synthyris pinnatifida.
