Name: Abies lowiana - Pinus ponderosa / Purshia tridentata Woodland
Reference: NatureServe Biotics 2019
Description: This woodland community is found in the East Cascade region of central and southern Oregon and extreme northern California. Typical elevations are between 1250-1800 m (4100-5886 feet). It occurs on a high variety of slopes and aspects with coarse sand and loamy sand soils. <i>Pinus ponderosa</i> generally dominates south aspects while <i>Abies lowiana</i> prevails on north aspects and higher elevations. <i>Purshia tridentata</i> is most common at lower slopes. At the upper elevations within its range, <i>Arctostaphylos patula</i> or <i>Ceanothus velutinus</i> may dominate. Common herbs include <i>Chamerion angustifolium, Apocynum androsaemifolium, Carex rossii</i>, and <i>Elymus elymoides ssp. elymoides</i>. This association becomes increasingly dominated by <i>Abies lowiana</i> in the absence of fire, which typically kills the younger fire-sensitive firs.
