Name: Populus tremuloides / Amelanchier alnifolia / Pteridium aquilinum Forest
Reference: NatureServe Biotics 2019
Description: This deciduous forest occurs on primarily on northerly and easterly exposures but has been seen on southeastern and southern exposures as well. It occurs at relatively low elevations in the mountains of northern Utah and western Wyoming. It is know from 2135 to 2193 m (7000-7195 feet) elevation. Soils are primarily derived from sandstone. It occurs on mid to lower slopes on up to 34% grades. The tree layer is almost exclusively <i>Populus tremuloides</i>. <i>Abies concolor</i> or <i>Abies lasiocarpa</i> may be present in the tree layer or as seedlings, but not in such abundance as to suggest eventual replacement of aspen dominance in the overstory. The tall-shrub stratum is dominated by <i>Acer grandidentatum, Prunus virginiana</i>, or <i>Amelanchier alnifolia</i>, or any combination of those species. Low shrubs, such as <i>Symphoricarpos oreophilus, Rosa woodsii</i>, or <i>Mahonia repens</i>, are also often present, sometimes in substantial amounts. The most distinctive feature is the abundance of <i>Pteridium aquilinum</i> in the herbaceous undergrowth. Forbs are often also present with <i>Osmorhiza</i> spp., <i>Galium boreale, Rudbeckia occidentalis</i>, and <i>Thalictrum occidentale</i>. Graminoids are also common with <i>Elymus glaucus, Bromus carinatus, Agrostis exarata, Calamagrostis rubescens, Juncus saximontanus, Carex laeviculmis</i>, and <i>Carex lenticularis</i>. This association is differentiated from the similar <i>~Populus tremuloides / Pteridium aquilinum</i> Forest (CEGL000597)$$ by the presence of an abundant tall-shrub layer.
