Name: Pinus ponderosa - Pseudotsuga menziesii / Penstemon fruticosus Woodland
Reference: NatureServe Biotics 2019
Description: Known only from a limited area in the eastern Cascades of Washington, this association is restricted climatically and to dry rocky soils derived from sandstone or basalt. An open canopy of <i>Pinus ponderosa</i> and <i>Pseudotsuga menziesii</i> trees with a sparse undergrowth of shrubs and herbaceous plants characterize this association. Shrub and/or herbaceous cover rarely exceed 20%. Hemi-sclerophyllous evergreen shrubs <i>Penstemon fruticosus, Ceanothus velutinus</i>, and <i>Mahonia nervosa</i> characterize this type, although deciduous shrubs <i>Holodiscus discolor</i> and <i>Spiraea betulifolia</i> are usually present but with low cover. <i>Balsamorhiza sagittata</i> and <i>Carex geyeri</i> are the most common herbaceous plants. This association is a small- to large-patch type that appears on dry rocky soils within a forest or woodland matrix.
