Name: Pinus ponderosa - Populus tremuloides / Carex spp. - (Poa spp.) Riparian Forest
Reference: NatureServe Biotics 2019
Description: This is a high-elevation ponderosa pine association found in the eastern Cascades of southern Oregon and the mountains of south-central Oregon between 1680 and 2105 m (5500-6900 feet) elevation. This is an open forest association with large <i>Pinus ponderosa</i> and <i>Populus tremuloides</i> trees and an open understory. In the tree understory <i>Juniperus occidentalis</i> is common, with occasional <i>Pinus contorta var. latifolia</i> and <i>Abies lowiana</i>. Shrubs occur at low cover, the most common shrubs include <i>Artemisia tridentata ssp. vaseyana, Amelanchier alnifolia, Symphoricarpos mollis, Mahonia aquifolium</i>, and <i>Ribes cereum</i>. The herbaceous layer is dominated by <i>Poa nervosa, Achillea millefolium, Elymus elymoides, Festuca idahoensis</i>, and <i>Fragaria virginiana</i>. Stands occur on all aspects and on gentle slopes (2-20%). This association supports lush vegetation adjacent to streambanks in bottoms with internal drainage. The soil surface is wet in spring and early summer, and the water table is near or at the surface year-round.
