Name: Pinus ponderosa - Populus tremuloides / Carex spp. - (Poa spp.) Forest
Reference: Western Ecology Working Group of...
Description: This is a high-elevation Ponderosa pine association, found between 5500 and 6900 feet. It occurs 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. This is an open forest association with large Pinus ponderosa and Populus tremuloides trees and an open understory. In the tree understory Juniperus occidentalis is common, with occasional Pinus contorta var. latifolia and Abies concolor. Shrubs occur at low cover, the most common shrubs include Artemisia tridentata ssp. vaseyana, Amelanchier alnifolia, Symphoricarpos mollis, Mahonia aquifolium (= Berberis aquifolium), and Ribes cereum. The herbaceous layer is dominated by Poa nervosa, Achillea millefolium, Elymus elymoides, Festuca idahoensis, and Fragaria virginiana.
