In the high Cascades of Washington, from the Stuart Range north into perhaps British Columbia, this association occurs mostly between the upper Chelan drainage to Mount Stuart. This may best be described as a parkland landscape often located near wetlands. It has a very open tree canopy usually with less than 25% cover. <i>Larix lyallii</i> is always present and often accompanied by <i>Abies lasiocarpa, Picea engelmannii, Pinus albicaulis</i>, or <i>Tsuga mertensiana</i>. Dwarf-shrubs dominate the ground cover, typically with less than 50% total cover. <i>Vaccinium deliciosum</i> and <i>Cassiope mertensiana</i> are always present, often with <i>Phyllodoce empetriformis, Luetkea pectinata</i>, or <i>Vaccinium scoparium</i>. Graminoids, such as <i>Luzula glabrata var. hitchcockii (= Luzula hitchcockii), Carex nigricans</i>, or <i>Vahlodea atropurpurea (= Deschampsia atropurpurea)</i>, commonly appear among the short shrubs. |

This riparian woodland association is found along creeks around the periphery of the Columbia Basin in Washington, Oregon and Idaho, primarily along the northern and southeastern edges. These are generally floodplain woodlands at low to mid elevations, in low-gradient valleys, or on terraces in narrower valleys, ranging from 4.5 m (15 feet) to over 305 m (1000 feet) wide. Streams are generally small, ranging from 1.5 to 9 m (5-30 feet) wide. Stands are dominated by <i>Pinus ponderosa</i> in the overstory, generally the only tree, averaging 36% cover. Rarely <i>Pseudotsuga menziesii, Populus tremuloides, Abies grandis</i>, or <i>Juniperus occidentalis</i> are present. <i>Symphoricarpos albus</i> dominates the understory, with 34% cover. In some stands, <i>Crataegus douglasii</i> may also be an important understory tall shrub, and <i>Prunus virginiana</i> or <i>Rosa</i> species are also not uncommon. Forbs and grasses dominate the forb layer. Most stands have been impacted by cattle, and as a result, <i>Poa pratensis</i> is dominant, along with other non-native grasses such as <i>Dactylis glomerata</i> and <i>Bromus orcuttianus</i>. However, native grass species including <i>Elymus glaucus, Elymus trachycaulus, Calamagrostis rubescens</i>, or <i>Bromus carinatus</i> are often present. Important forbs include <i>Maianthemum stellatum, Fragaria virginiana, Galium boreale</i>, and <i>Achillea millefolium</i>. |
