Name: Pinus ponderosa - Quercus garryana / Balsamorhiza sagittata Woodland Reference: NatureServe Biotics 2019 Description: This mixed evergreen-deciduous woodland occupies hot, dry sites between 645-1060 m elevation on the eastern slope of the Oregon Cascades. Stands normally grow on ridges and upper slope positions of south-facing hillsides. Temperatures are very warm during the growing season and precipitation is low. These conditions limit the cover of trees and shrubs. The tree canopy is dominated by <i>Pinus ponderosa</i> and <i>Quercus garryana</i> with an occasional <i>Pseudotsuga menziesii</i>. Average tree cover is 50%, with <i>Pinus ponderosa</i> slightly more dominant than <i>Quercus garryana</i>. Trees are short and sparse. The shrub layer is also quite sparse, generally confined to small amounts of <i>Ceanothus prostratus, Ceanothus integerrimus</i>, or <i>Symphoricarpos</i> sp. Average cover of shrubs is only about 5%. The herbaceous flora is diverse, with <i>Balsamorhiza sagittata</i> the diagnostic species. <i>Lupinus caudatus</i> and <i>Lomatium triternatum</i> are always present and conspicuous. The graminoid layer is dominated by <i>Festuca idahoensis</i> and <i>Pseudoroegneria spicata</i>. This association has sparser shrub cover than ~<i>Pinus ponderosa - Quercus garryana / Purshia tridentata</i> Woodland (CEGL000883)$$.  Accession Code: urn:lsid:vegbank.org:commConcept:29790-{96796281-3E4E-4885-B877-58B8D3FE749C} Plot-observations of this Community Concept: 0
