Name: Populus tremuloides / Spiraea betulifolia Forest Reference: Western Ecology Working Group of... Description: This aspen forest type is found on gently sloping or rolling topography, at higher elevations in the Central Core, Limestone Plateau, Minnekahta Foothills and Bear Lodge Mountains of the Black Hills in the United States. It has also been found in western Montana in Glacier National Park. In the Black Hills, aspen stands are best developed and extend to lower elevations (1586-1740 m) in the northern part of the range, including the Bear Lodge Mountains. In northwestern Montana, this type was found at 1537 m (5040 feet) on a moderately steep, south-facing talus slope composed of limestone and dolomite rocks. This type can have a moderately closed to closed canopy. <i>Populus tremuloides</i> is the dominant tree. <i>Picea glauca, Pinus contorta</i>, or <i>Pinus ponderosa</i> may occur in this community as emergent trees. Understory composition was found to be quite variable in stands surveyed. Shrub cover typically is heavy and diverse, with <i>Spiraea betulifolia</i> and <i>Mahonia repens</i> often codominant. Other shrubs frequently present include <i>Amelanchier alnifolia, Arctostaphylos uva-ursi, Prunus virginiana, Rosa woodsii, Shepherdia canadensis</i>, and <i>Symphoricarpos albus</i>. The herbaceous stratum also is diverse, and forb cover often is greater than graminoid cover. <i>Symphyotrichum laeve (= Aster laevis), Lathyrus ochroleucus</i>, and <i>Monarda fistulosa</i> are among the more abundant species. The one stand sampled in Glacier National Park had no herbaceous species present.  Accession Code: VB.CC.33045.CEGL000607 Plot-observations of this Community Concept: 0
