Name: Pinus ponderosa / Purshia tridentata / Festuca idahoensis Woodland Reference: Western Ecology Working Group of... Description: This association is a widespread woodland community which is a dominant part of the landscape in the eastern Cascades, and occurs as patches throughout the Blue Mountains, and in Idaho, northeastern Washington and Montana. Elevations vary between 780-1740 m (2550-5700 feet) on all aspects with slopes usually less than 35%. Soils are a mixture of sand, loam, and silt. These woodlands are dominated by <i>Pinus ponderosa</i> (5-60% cover) with occasional <i>Pinus contorta, Juniperus occidentalis</i>, or <i>Cercocarpus ledifolius</i> (less than 10% cover). The shrub layer is characterized by <i>Purshia tridentata</i> up to 50% cover with occasional <i>Arctostaphylos patula, Ericameria bloomeri</i>, and <i>Ceanothus integerrimus</i>. The herbaceous layer is usually dominated by <i>Festuca idahoensis</i> (5-40% cover) with minor herbs such as <i>Elymus elymoides ssp. elymoides (= Sitanion hystrix), Achnatherum occidentale ssp. occidentale (= Stipa occidentalis), Lupinus</i> spp., <i>Achillea millefolium</i>, and <i>Fragaria virginiana</i>. Fires have historically maintained <i>Pinus ponderosa</i> while thinning fire-sensitive subordinate trees and shrubs.  Accession Code: VB.CC.33186.CEGL000195 Plot-observations of this Community Concept: 0
