Name: Picea engelmannii / Trifolium dasyphyllum Forest Reference: NatureServe Biotics 2019 Description: This association is known only from the Front Range of north-central Colorado. It occurs from 3300-3450 m (10,810-11,320 feet) elevation, just below krummholz timberline, on moderately steep north-facing slopes that are mostly convex to undulating. Sites can be characterized as relatively xeric, cold and exposed. Soils are derived primarily from granitic colluvial parent materials; they are minimally developed Typic Cryorthents: shallow, coarse-textured (sandy loams), and with rocks on the surface. This is a forest association typically dominated by the evergreen needle-leaved tree <i>Picea engelmannii</i>, both in the canopy and as seedlings and saplings in the understory. <i>Abies lasiocarpa, Pinus flexilis</i>, and <i>Pinus aristata</i> are minor components in the canopy and very infrequent in the understory. There is no shrub layer. The herbaceous understory layer is sparse, with total cover averaging &lt;15%. The perennial forbs <i>Trifolium dasyphyllum</i> and <i>Trifolium parryi</i> are the only abundant herbaceous species, averaging 6% and 3% cover, respectively. The remaining herbaceous species are a mix of perennial graminoids and forbs; important species include the graminoids <i>Festuca brachyphylla</i> and <i>Trisetum spicatum</i>, and the forbs <i>Arenaria fendleri, Penstemon whippleanus, Pyrola minor</i>, and <i>Sedum stenopetalum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:29286-{CB700B06-86EB-4024-8CF2-93158AD516D4} Plot-observations of this Community Concept: 0
