CEGL005929 Pinus contorta / Cornus sericea Swamp Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Lodgepole Pine / Red-osier Dogwood Swamp Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland association is found on cool, moist sites in the mountains of the northern Rocky Mountains of western Montana and southern Alberta. This community occurs from 823 to 1628 m (2700-5340 feet) in elevation across its range. It is restricted to flat or gently sloping alluvial terraces or benches and, less frequently, moist toeslopes. Stands may be temporarily flooded in the spring, and due to the location in riparian zones, the water table is usually within 1 m of the surface. Water flow and aeration in the rooting zone are usually good. The vegetation is characterized by an overstory tree canopy dominated by Pinus contorta. Populus tremuloides, Populus balsamifera ssp. trichocarpa, or Betula papyrifera are often present in the canopy. Picea engelmannii may be present in the understory but does not form a significant part of the tree canopy. Shrub cover is typically high, with Cornus sericea usually the dominant shrub. Other shrubs such as Acer glabrum, Alnus incana, Amelanchier alnifolia, Linnaea borealis, Ribes lacustre, Rosa woodsii, Rubus parviflorus, various Salix spp., Shepherdia canadensis, and Symphoricarpos albus are often present. Herbaceous cover is low, but forb species richness is often high. Common forbs include Fragaria virginiana, Galium spp., Osmorhiza berteroi, Maianthemum stellatum, Senecio triangularis and Thalictrum occidentale.

Classification Comments: This seral Pinus contorta association was included in concepts of Picea / Cornus stolonifera Habitat Type (Hansen et al. 1995). The Sierra Nevada Pinus contorta / Cornus stolonifera Forest stand described by Manning and Padgett (1995) is possibly a different association. The Picea / Cornus stolonifera Community Type reported by Youngblood et al. (1985a) for eastern Idaho and western Wyoming does not include any sampled stands with Pinus contorta as a seral component. This association appears to be a relatively dry riparian association. Flooding does not seem to be an important factor for its occurrence, but high water tables are important.

Floristics: This woodland is characterized by an overstory tree canopy dominated by Pinus contorta. Populus tremuloides, Populus balsamifera ssp. trichocarpa, or Betula papyrifera are often present in the canopy. Picea engelmannii may be present in the understory but does not form a significant part of the tree canopy. These sites are typically too low in elevation to have much presence of Abies lasiocarpa. Shrub cover is typically high, with Cornus sericea usually the dominant shrub. Other shrubs such as Acer glabrum, Alnus incana, Amelanchier alnifolia, Linnaea borealis, Ribes lacustre, Rosa woodsii, Rubus parviflorus, various Salix spp., Shepherdia canadensis, and Symphoricarpos albus are often present. Herbaceous cover is low, but forb species richness is often high. Common forbs include Fragaria virginiana, Galium spp., Osmorhiza berteroi (= Osmorhiza chilensis), Prosartes trachycarpa (= Disporum trachycarpum), Maianthemum stellatum, Pteridium aquilinum, Senecio triangularis, and Thalictrum occidentale.

Environmental Description: This woodland is found on cool, moist sites in the mountains of the northern Rocky Mountains. This community occurs from 823 to 1628 m (2700-5340 feet) in elevation across its range. It is restricted to flat or gently sloping alluvial terraces or benches and, less frequently, moist toeslopes. The alluvial soils are usually finer-textured with high organic content and gleying and mottling. Stands may be temporarily flooded in the spring, and due to its location in riparian zones, the water table is usually within 1 m of the surface. Water flow and aeration in the rooting zone are usually good.
Geographic Range: This riparian woodland association occurs in the northern Rocky Mountains of western Montana and extends north into Alberta, Canada.
