Sites include stream terraces, low slopes and high slopes on north, east and northwest aspects. Substrates are rocky with variable soil drainage composed of sandy loam, loamy sand, clay loam, and silty clay.

Other canopy associates may include Pinus flexilis and Pinus longaeva at low covers. A sparse canopy of Juniperus scopulorum and Cercocarpus ledifolius may be present. The understory is characterized by an open shrub layer dominated by Symphoricarpos oreophilus. Other shrub associates may include Acer glabrum, Apocynum cannabinum, Arctostaphylos patula, Artemisia tridentata ssp. vaseyana, Ceanothus martinii, Chrysothamnus viscidiflorus, Gutierrezia sarothrae, and Holodiscus dumosus. The herbaceous layer is sparse without apparent dominants.
