Name: Picea glauca Black Hills Forest Alliance
Reference: NatureServe Biotics 2019
Description: This is a restricted alliance found in high elevations of the Black Hills and possibly Bighorn Mountains of Wyoming and South Dakota, and dominated by <i>Picea glauca</i>, with or without <i>Populus tremuloides</i> and <i>Pinus ponderosa</i>. The latter two species are remnants from earlier successional stages and do not reproduce successfully. There is a prominent low-shrub layer with common constituents including <i>Arctostaphylos uva-ursi, Juniperus communis, Linnaea borealis, Mahonia repens, Rosa acicularis, Shepherdia canadensis</i>, and <i>Symphoricarpos albus</i>. The herbaceous layer is less dense and typically contains <i>Achillea millefolium, Fragaria virginiana, Galium boreale, Hedysarum alpinum</i>, and <i>Oryzopsis asperifolia</i>. Mosses and lichens are common. This type is also found in limited areas of floodplains in the Black Hills where <i>Picea glauca</i> occurs with <i>Betula papyrifera</i> and <i>Populus tremuloides</i>. <i>Corylus cornuta</i> is a common understory shrub. This alliance occurs on moderate (28-63%) slopes on loamy soils. It generally occurs at the higher elevations in the Black Hills and has been sampled from 1737-2040 m (5700-6693 feet). Most sites are on northeast- to northwest-facing slopes, but other aspects are possible.
