Name: Bromus marginatus - Pseudoroegneria spicata Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This is a mesic to subhygric, diverse grassland found uncommonly in the lower subalpine region of Waterton Lakes National Park, Alberta. This association occurs on moderately steep midslopes at elevations near 1725 m (5650 feet) on easterly aspects. Soils are derived from coarse fluvial or hard rock calcareous parent material and are characterized as either Cumulic Humic Regosols or Eluviated Eutric Brunisols. These are generally moderately well-drained, coarse-textured soils developed on morainal or rock landforms. Litter and small rock dominate the ground surface. This herbaceous association is dominated by several grass and forb species. Overall herbaceous cover ranges between 90-100% with heights less than 0.5 m. Dominant species, averaging between 8-25% cover, include <i>Pseudoroegneria spicata, Bromus marginatus, Lomatium triternatum, Phleum pratense, Poa palustris</i>, and <i>Eurybia conspicua (= Aster conspicuus)</i>. Other common herbaceous species include <i>Lupinus sericeus, Osmorhiza occidentalis, Calochortus apiculatus, Valeriana dioica, Achillea millefolium, Aquilegia flavescens, Fragaria virginiana, Galium boreale, Hedysarum sulphurescens, Thalictrum occidentale</i>, and <i>Zigadenus elegans</i>. Cover of <i>Erigeron peregrinus, Anemone multifida</i>, and <i>Geranium viscosissimum</i> may be conspicuous in certain areas. Low shrubs may also be present with very low cover. Cover of nonvascular species averages 5%.
