Description: This successionally intermediate alliance occurs in the Black Hills and western and northwestern United States. This description is strongly based on the portion of this alliance that occurs in the Black Hills. This is a mixed evergreen - deciduous forest composed of short to moderately tall trees. Sites can be on gentle to steep slopes and have any aspect. The canopy is variable, ranging from moderately open to closed. Younger stands typically have dense ~Populus tremuloides$ with ~Pinus ponderosa$ mixed in. As the stands age, ~Populus tremuloides$ is slowly reduced and ~Pinus ponderosa$ becomes dominant. ~Betula papyrifera$ and ~Picea glauca$ may be minor components of the canopy. The shrub layer contains species such as ~Arctostaphylos uva-ursi, Juniperus communis, Prunus americana, Prunus pensylvanica, Prunus virginiana, Rubus idaeus, Sorbus scopulina$, and ~Vaccinium scoparium$. ~Aralia nudicaulis, Castilleja sulphurea, Clematis columbiana, Geranium richardsonii, Oryzopsis asperifolia, Pteridium aquilinum$, and ~Sedum stenopetalum$ are found in the herbaceous stratum. Stands of this alliance typically develop after a crown fire or other disturbance has removed the ~Pinus ponderosa$ overstory.
