Name: Carex rupestris - Trifolium dasyphyllum Alpine Turf Reference: NatureServe Biotics 2019 Description: This southern Rocky Mountain association is found in upland subalpine and alpine environments along the Continental Divide and east of the divide in the Front Range. Sites are typically dry meadows and alpine turf at middle to lower alpine and around treeline often in transition areas with fell-fields. Stands often occur on flat and convex mid to upper slopes that are moderate to somewhat steep (20-40%), often in saddles (5-10%), that are moderately exposed to prevailing winds that keep sites snow free most of the winter. Aspects are variable. Substrates are moderately shallow, well-drained gravelly to cobbly, silty to sandy loams. There is often moderate cover of large and small surface rocks and bare ground, especially in transition areas with fell-fields. Sites are less mesic and soils coarser and less developed than <i>Kobresia myosuroides</i>-dominated alpine turf. Vegetation of this alpine turf association is characterized by a moderately dense to dense (&gt;50% cover) herbaceous layer dominated by <i>Carex rupestris</i> with <i>Trifolium dasyphyllum</i> and <i>Geum rossii</i> codominant. Other important species with lower cover include graminoids <i>Elymus scribneri, Calamagrostis purpurascens, Carex elynoides, Danthonia intermedia, Festuca brachyphylla, Poa glauca ssp. rupicola, Trisetum spicatum</i>, and forbs <i>Arenaria fendleri, Artemisia scopulorum, Tonestus pygmaeus, Oreoxis alpina</i>, and <i>Sedum stenopetalum</i>. <i>Minuartia obtusiloba, Paronychia pulvinata, Silene acaulis</i>, and other cushion plants are more evident in this turf. Cover of mat-forming dwarf-shrubs, such as <i>Artemisia arctica ssp. arctica</i> and <i>Paronychia pulvinata</i>, and moss and lichen is significant in some stands.  Accession Code: urn:lsid:vegbank.org:commConcept:30772-{E721E957-0607-42CC-A68E-F37EF96C0C79} Plot-observations of this Community Concept: 0
