Name: Populus tremuloides / Senecio bigelovii var. bigelovii Forest Reference: Western Ecology Working Group of... Description: This plant association is an infrequently occurring community in the Rampart Range and the Wet Mountains of the Front Range of Colorado. It occurs at elevations ranging from 2620-2755 m (8600-9040 feet) on gently sloping east-, west-, or northeast-facing swales on cool, moist sites. The overstory is dominated by Populus tremuloides (50-75% cover) with a minor tree understory of Abies concolor (<3% cover), Picea pungens (0-10% cover), Pinus contorta (<3% cover), and Pseudotsuga menziesii (<3% cover). Total shrub cover ranges from 1-30% and may include Arctostaphylos uva-ursi (0-10% cover), Juniperus communis (0-15% cover), and Rosa woodsii (0-15% cover). The herbaceous layer consists of 22% cover graminoids and 71% cover forbs. The forbs are diverse, but Senecio bigelovii var. bigelovii (= Ligularia bigelovii) is always present with at least 20% cover (20-45%); other forbs that may be present with high cover are Achillea millefolium (2-15%), Aconitum columbianum (0-10%), Symphyotrichum laeve (= Aster laevis) (0-15%), Fragaria virginiana (10-20%), Geranium richardsonii (5-25%), Pedicularis procera (= Pedicularis grayi) (0-15%), Potentilla gracilis (0-30%), Thalictrum fendleri (0-20%), and Vicia americana (0-30%).  Accession Code: VB.CC.23296.POPULUSTREMULOI Plot-observations of this Community Concept: 0
