click to update datacart
Name: Pinus aristata / Trifolium dasyphyllum Woodland Reference: NatureServe Biotics 2019 Description: This association is known only from the southern Arapaho National Forest in north-central Colorado, in the Front Range west of Denver. This association occurs from 3430 to 3550 m (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. This is a woodland association dominated by the evergreen needle-leaved tree <i>Pinus aristata</i>, averaging 40-50% cover. <i>Picea engelmannii</i>, 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 &lt;20%. The perennial forb <i>Trifolium dasyphyllum</i> clearly dominates, with 10-12% cover. The remaining herbaceous species are a mix of perennial graminoids and forbs; important species include the graminoids <i>Calamagrostis purpurascens, Carex siccata, Festuca brachyphylla</i>, and <i>Trisetum spicatum</i>, and the forbs <i>Achillea millefolium, Arenaria fendleri, Penstemon whippleanus, Polemonium pulcherrimum ssp. delicatum, Sedum stenopetalum</i>, and <i>Solidago simplex</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:29671-{545B2AFA-3C7A-486F-83CE-E36917A92344} Plot-observations of this Community Concept: 0
