Bristlecone Pine Forest (Hudsonian Life Zone)

Non-technical description: A high-elevation, Bristlecone Pine forest with few shrubs. Trees decline in height to dwarfed, gnarled, prostrate individuals deformed by the wind near timberline.

In other areas, the Hudsonian Life Zone is a spruce-fir association where common species include Engelmann spruce (Picea engelmanni), alpine fir (Abies lasiocarpa) and Great Basin Bristlecone Pine (Pinus longaeva). For the most part, we have only Bristlecone Pine  and a few Limber Pine (Pinus flexilis) in this life zone. The understory usually is open, but may include Wax Currant (Ribes cereum), Bunchgrasses, and Common Juniper (Juniperus communis), a low-growing shrub-juniper. Trees decline in height to dwarfed, gnarled, prostrate individuals deformed by the wind near timberline. Deciduous trees in this life zone include Quaking Aspen (Populus tremuloides).
