This variable woodland association has only been described from the Ochoco Mountains in central Oregon. The association occurs at elevations between 1100 and 1770 m (3600-5800 feet). Sites are considered transitional between true riparian and upland and are usually flat to slightly concave. Soils are derived from alluvium, ash deposited on colluvium, or mixtures of both. They are near water sources such as streams, springs, or wet meadows. Surface horizons range from fine sandy loams to clay loams. <i>Populus tremuloides</i> cover ranges between 38 and 83%. <i>Pinus ponderosa</i> may also occur in the upper canopy but is less than 40% cover. The shrub layer is dominated by <i>Symphoricarpos albus</i> which covers 7-70%. Other shrubs are markedly absent. <i>Elymus glaucus</i> and less commonly, <i>Poa pratensis</i>, may each reach 25% cover. Forbs usually associated with this community include <i>Achillea millefolium var. occidentalis (= Achillea lanulosa), Osmorhiza</i> spp., <i>Aquilegia formosa, Galium boreale, Galium mexicanum ssp. asperrimum (= Galium asperrimum)</i>, and <i>Maianthemum stellatum</i>. |

This Rocky Mountain montane riparian woodland association is known from Montana, Idaho and Colorado. Elevations range from 1100 to 2590 m (3600-8500 feet). Stands occur on floodplains and benches along drainages and adjacent lower hill slopes in narrow valleys. Stream channels are typically narrow and steep, but also include major streams and rivers. Substrates are usually well-drained soils with clay loam to sandy loam textures derived from various alluvial or colluvial parent materials. Ground surface has high cover of litter. The vegetation is characterized by the overstory tree canopy dominated by <i>Pseudotsuga menziesii</i> with <i>Cornus sericea</i> prominent in the shrub understory. Other tree species present include <i>Abies concolor, Abies lasiocarpa, Acer negundo, Juniperus scopulorum, Picea engelmannii, Picea pungens, Populus angustifolia, Populus balsamifera ssp. trichocarpa</i> or <i>Populus tremuloides</i>. The lush shrub layer is dominated or codominated by <i>Cornus sericea</i> with 10-75% cover. Other common shrubs include <i>Acer glabrum, Amelanchier alnifolia, Alnus incana, Mahonia repens, Prunus virginiana, Quercus gambelii, Rosa woodsii, Salix exigua, Spiraea betulifolia</i>, and <i>Symphoricarpos</i> spp. The herbaceous layer is sometimes sparse due to the dense shrub canopy, but when the shrub canopy is disturbed graminoids such as <i>Poa pratensis, Calamagrostis rubescens</i>, or <i>Elymus glaucus</i> dominate. Forb diversity is typically high with common forbs including <i>Actaea rubra, Fragaria virginiana, Geranium</i> spp., <i>Heracleum maximum, Maianthemum</i> spp., <i>Osmorhiza</i> spp., and <i>Thalictrum occidentale</i>. |
