Midwestern Ecology Working Group...
Description:
This aspen forest type is found in the Rocky Mountains and Black Hills of the western United States. It occurs on slope crests and midslopes with sandy loam, loam, or clay loam soils from approximately 1545 to 2720 m (5100-8980 feet) in elevation. Aspects are highly variable, and slopes are primarily gentle (0-20%) but may also be steep (50-100%). This association is dominated by <i>Populus tremuloides</i>. Conifers are sparse when present and can include <i>Pseudotsuga menziesii, Pinus contorta, Pinus ponderosa</i>, and <i>Picea glauca</i> in the Black Hills. The shrub layer can be a rich multilayered mixture of medium- and low-height shrubs. <i>Prunus virginiana</i> is often dominant or codominant with <i>Amelanchier alnifolia</i>. Additional shrub associates can include <i>Acer grandidentatum, Ribes inerme, Ribes oxyacanthoides ssp. setosum (= Ribes setosum), Rosa woodsii, Cornus sericea, Paxistima myrsinites, Rubus parviflorus, Symphoricarpos occidentalis</i>, and <i>Symphoricarpos oreophilus</i>. Herbaceous species can have low cover due to the well-developed shrub layer but commonly include <i>Agastache urticifolia, Aralia nudicaulis, Bromus carinatus, Carex sprengelii, Calamagrostis rubescens, Carex geyeri, Elymus glaucus, Fragaria virginiana, Galium boreale, Geranium viscosissimum, Maianthemum stellatum, Osmorhiza depauperata, Osmorhiza berteroi (= Osmorhiza chilensis), Rudbeckia occidentalis, Senecio serra</i>, and <i>Thalictrum fendleri</i>. Diagnostic features of this association are <i>Populus tremuloides</i> dominant in the canopy and <i>Prunus virginiana</i> well-represented in the shrub layer.
