Name: Pinus ponderosa / Purshia tridentata / Carex rossii Woodland
Reference: NatureServe Biotics 2019
Description: This woodland is found in the southern Blue Mountains, the Ochoco Range, and southeastern Oregon Cascades. Elevations are between 1020-1980 m (3350-6500 feet) with generally low steepness (0-50%) and a variety of aspects, but favoring southerly exposures in the Blue Mountains. Soils are sandy loams, silt, and loamy sand. The overstory is dominated by <i>Pinus ponderosa</i> with occasional <i>Juniperus occidentalis</i>. The shrub layer is characterized by <i>Purshia tridentata</i> and occasional <i>Mahonia repens</i>. The herbaceous layer is usually dominated by <i>Carex rossii</i>. Other herbaceous species include <i>Achnatherum occidentale ssp. occidentale</i> and <i>Elymus elymoides ssp. elymoides</i>. Occasionally, <i>Achillea millefolium</i> and <i>Fragaria virginiana</i> are present. This association is well-adapted to periodic surface fires which promote regeneration of <i>Pinus ponderosa</i>. It occupies warm and moist sites as compared to other <i>Pinus ponderosa / Purshia tridentata</i> associations.
