Reference:
Western Ecology Working Group of...
Description:
This association is described from subalpine meadows in Wyoming and eastern Idaho and is expected to occur in northern Utah. Elevation ranges from 2400 to 2720 m (7900-10,400 feet). It occurs adjacent to small stream channels, near small seeps and springs, on toeslopes, moist sites on lower slopes, and flat benches in narrow to moderately wide valley bottoms. Above treeline this association is common on gentle to steep slopes on talus debris in the Bridger Wilderness, Wyoming. Soils are deep Mollisols with fine-loamy textures. Soils are well-drained but moist throughout the growing season. Stands are often narrow strings limited to the streambank and are dominated by <i>Mertensia ciliata</i>. Other forbs present are highly variable and include <i>Arnica latifolia, Rudbeckia occidentalis, Senecio triangularis, Valeriana occidentalis, Erigeron peregrinus, Mitella pentandra, Parnassia fimbriata, Rhodiola rhodantha (= Sedum rhodanthum), Heracleum maximum, Delphinium x occidentale, Geranium richardsonii, Hymenoxys hoopesii (= Helenium hoopesii), Saxifraga odontoloma, Senecio crassulus, Thalictrum occidentale</i>, and <i>Lupinus argenteus</i>. Graminoids present include <i>Bromus carinatus, Phleum alpinum, Carex microptera, Juncus balticus, Elymus caninus (= Agropyron caninum), Poa trivialis</i>, and <i>Deschampsia caespitosa</i>. A few <i>Salix</i> shrubs may be creep into this association from nearby or adjacent wetland shrublands.
