Hierarchy Level:  Association

Type Concept: This lodgepole pine woodland is known from Glacier National Park, Montana, and Waterton Lakes National Park, Alberta. Occurrences are found predominately on middle portions of gentle to steep slopes of various aspects. These mesic sites are usually situated on glacial or thin colluvial deposits between the elevations of 970 and 1720 m (3180-5639 feet). Soils tend to be well-drained Orthic Regosols. The ground surface is mostly covered with litter, duff, and wood. This woodland association is dominated by a pole to mature open tree canopy of Pinus contorta (35% average cover); its average height varies between 10 and 15 m. Tree seedlings of Picea engelmannii and Abies lasiocarpa have low constancy. Spiraea betulifolia, Rubus parviflorus, and Symphoricarpos albus are typically present within the short-shrub layer. The lush herbaceous layer is dominated by a mix of mesic-site indicators of varying constancy, including Angelica spp. (Angelica dawsonii and Angelica arguta), which are nearly always present, and Galium triflorum, Heracleum maximum, Osmorhiza occidentalis, Streptopus amplexifolius, and Actaea rubra. Numerous graminoids and other forbs contribute cover to this layer, most with inconspicuous cover. Common species include Chamerion angustifolium, Arnica cordifolia, Thalictrum occidentale, Calamagrostis rubescens, and Galium boreale.
