Name: Populus balsamifera ssp. trichocarpa / Calamagrostis canadensis Forest
Reference: Western Ecology Working Group of...
Description: This association is currently known from one low-elevation site in Waterton Lakes National Park, Alberta. It was sampled at 1440 m (4721 feet) on a gently sloping fluvial fan. The stand occurs on temporarily flooded, but well-drained, Orthic Humic Regosol soil. Multi-aged <i>Populus balsamifera ssp. trichocarpa</i> dominates this association, with 20% cover in the tree canopy and up to 10% cover in the subcanopy and young tree layers. <i>Populus tremuloides</i> is subdominant, with up to 10% cover in both canopy and reproduction layers. <i>Symphoricarpos occidentalis</i> dominates a short-shrub layer with 30% cover, while <i>Rosa woodsii</i> and <i>Spiraea betulifolia</i> are also present. Tall grasses dominate the herbaceous layer, although a diverse mix of both tall and ground-layer forbs are also present. The most important grasses are <i>Calamagrostis canadensis</i> and <i>Elymus glaucus</i>, each with 15% cover, and <i>Phleum pratense</i> with 10% cover. The most abundant forbs are <i>Cirsium arvense, Chamerion angustifolium, Eucephalus engelmannii</i>, and <i>Galium triflorum</i>. Less abundant forbs include <i>Actaea rubra, Fragaria virginiana, Geranium richardsonii, Heracleum maximum</i>, and <i>Viola canadensis</i>. The ground cover is primarily litter and duff with 5% cover of mosses.
