Name: Pinus aristata / Trifolium dasyphyllum Woodland Reference: Western Ecology Working Group of... Description: This is a woodland association dominated by the evergreen needle-leaved tree Pinus aristata, averaging 40-50% cover. Picea engelmannii, another coniferous tree, is present as scattered individuals. Seedlings and saplings of either species are infrequent and shrubs are absent from most stands. The herbaceous understory layer is moderately sparse, with total cover averaging <20%. The perennial forb Trifolium dasyphyllum clearly dominates, with 10-12% cover. The remaining herbaceous species are a mix of perennial graminoids and forbs; important species include the graminoids Calamagrostis purpurascens, Carex siccata (= Carex foenea), Festuca brachyphylla, and Trisetum spicatum, and the forbs Achillea millefolium, Arenaria fendleri, Penstemon whippleanus, Polemonium pulcherrimum ssp. delicatum, Sedum stenopetalum, and Solidago simplex. Known only from the southern Arapaho National Forest in north-central Colorado, in the Front Range west of Denver. This association occurs from 11,240-11,645 feet elevation, just below timberline, on moderate to steep slopes of varying aspects. Sites can be characterized as harsh and xeric, with desiccating winds and broadly fluctuating temperatures. Soils are derived primarily from granitic parent materials. They are minimally developed Typic Cryorthents: shallow, coarse-textured (sandy loams), and with rocks on the surface.  Accession Code: VB.CC.20434.PINUSARISTATATR Plot-observations of this Community Concept: 0
