Description: This is a restricted alliance found in high elevations of the Black Hills. Sites in this alliance have a closed canopy of ~Picea glauca$, often with lesser amounts of ~Populus tremuloides$ and ~Pinus ponderosa$. The latter two species are remnants from earlier successional stages and do not reproduce successfully (Hoffman and Alexander 1987). There is a prominent low-shrub layer in this alliance. Its most common constituents are ~Arctostaphylos uva-ursi, Juniperus communis, Linnaea borealis, Mahonia repens, Rosa acicularis, Shepherdia canadensis$, and ~Symphoricarpos albus$. The herbaceous layer is less dense. It typically contains ~Achillea millefolium, Fragaria virginiana, Galium boreale, Hedysarum alpinum$, and ~Oryzopsis asperifolia$. Mosses and lichens are common in this alliance. ^This alliance occurs on moderate (28-63%) slopes on loamy soils (Johnston 1987). It generally occurs at the higher elevations in the Black Hills and has been sampled from 1737-2040 m (5700-6693 feet) (Hoffman and Alexander 1987). Most sites are on northeast- to northwest-facing slopes, but other aspects are possible.
