Description: This is a sagebrush opening in <i>Pinus contorta</i> or <i>Pinus ponderosa</i> forests in the East Cascades and Modoc Plateau of south-central Oregon and northeastern California. It is found between 1465 and 1495 m (4800-4900 feet) in elevation on very deep Mazama ash deposits under 5-7 inches of loamy sand. <i>Artemisia tridentata ssp. vaseyana</i> is the dominant shrub, with up to 10-30% cover in the Deschutes National Forest and 55% in the one plot from central Oregon. <i>Achnatherum occidentale (= Stipa occidentalis)</i> is the only grass reported from this community in central Oregon, while <i>Carex rossii</i> and <i>Elymus elymoides</i> were occasional in the East Cascades. Prominent forbs are <i>Eriogonum flavum, Eriogonum umbellatum, Eriogonum ovalifolium, Polygonum phytolaccifolium, Lupinus</i> spp., <i>Eriophyllum lanatum</i> and <i>Antennaria dimorpha</i>.
