Description: This is an open woodland found in the eastern Cascades ecoregion in south-central Oregon. This association occurs at elevations between 1525 and 1950 m (5000-6400 feet) in eastern Oregon. Slopes vary from 5-40%. Sites are usually on convex topography over andesite, basalt, or rhyolite. Soils are gravelly silt loams to gravelly clay, and are well-drained. <i>Pinus ponderosa</i> is the major tree cover, varying from 5-50%. <i>Abies lowiana</i> often occurs at the upper elevational phases of this association but remains &lt;10% cover. <i>Juniperus occidentalis</i> may occur at &lt;10% cover. <i>Wyethia mollis</i> occurs at &lt;30% cover except in recently disturbed sites where it may be over 50% cover. Other shrubs usually found are <i>Purshia tridentata</i> and <i>Amelanchier alnifolia</i> usually exist at low cover values. <i>Achillea millefolium</i> is usually found up to 10% cover. A number of other forbs and grasses can be found. No single grass species (<i>Elymus elymoides</i> and <i>Poa nervosa</i>) covers more than 10%.
