Name: Populus tremuloides / Juniperus communis / Carex geyeri Forest Reference: NatureServe Biotics 2019 Description: This deciduous forest is known from the southern and central Rocky Mountains and northern Colorado Plateau where it occurs on mountain slopes. Elevations range from 2400-2700 m (8000-9000 feet). Stands occur on gentle to moderately steep slopes (&lt;40%) with southeastern aspects. Substrates are variable, but soils tend to be well-drained loams or silty loams. Litter covers much of the ground surface. The vegetation is characterized by a moderately dense to dense tree canopy dominated by <i>Populus tremuloides</i>, a low-shrub layer (&gt;10% cover) with <i>Juniperus communis</i> dominant or at least prominent, and a <i>Carex geyeri</i>-dominated herbaceous layer. Several other shrubs, such as <i>Mahonia repens, Paxistima myrsinites, Symphoricarpos oreophilus</i>, or <i>Symphoricarpos rotundifolius</i>, may also be present in the low-shrub layer. Scattered conifers may be present in the tree canopy, and occasional <i>Amelanchier alnifolia</i> and conifer saplings are present but do not form a tall-shrub layer. The moderate herbaceous layer is mostly graminoids and characteristically dominated by <i>Carex geyeri</i> or <i>Calamagrostis rubescens</i>, but other graminoids present may include <i>Achnatherum occidentale, Elymus trachycaulus, Festuca thurberi</i>, and the introduced perennial grass <i>Poa pratensis</i>. Forb cover is typically low but may be moderately diverse.  Accession Code: urn:lsid:vegbank.org:commConcept:29497-{890C6591-ABDB-4C2F-993B-60685BACBD70} Plot-observations of this Community Concept: 0
