Name: Populus tremuloides / Acer glabrum Forest Reference: Western Ecology Working Group of... Description: This uncommon forest association is found in a mountainous region east of the Continental Divide in central Colorado. Stands probably also occur in north-central New Mexico where it may be seral to conifer forests with Acer glabrum-dominated understories. Sites are described as north- to northeast-facing, moist-wet alluvial terraces at 2800 m elevation. Slopes are moderately steep and undulating. Soils are saturated or poorly drained. The tree canopy is characterized by a nearly closed canopy of the broad-leaved deciduous tree Populus tremuloides. Populus balsamifera may be present in some stands. The understory is very lush, with both shrub and herbaceous layers having over 100% cover. Shrubs are primarily broad-leaved deciduous, with Acer glabrum being the characteristic and dominant species. Occasionally Acer glabrum may reach tree stature. Other important tall shrubs include Sambucus racemosa, Prunus virginiana, Ribes montigenum, and Mahonia repens. The herbaceous layer is dominated by perennial forbs, such as Artemisia franserioides, Erigeron eximius, Maianthemum stellatum, Osmorhiza depauperata, Oreochrysum parryi (= Solidago parryi), and Thalictrum fendleri. Species richness is moderately high for aspen associations. Diagnostic of this forest association is the tree canopy dominated by Populus tremuloides with an Acer glabrum-dominated tall-shrub layer.  Accession Code: VB.CC.23938.POPULUSTREMULOI Plot-observations of this Community Concept: 0
