CEGL003151 Juniperus grandis / Artemisia tridentata Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Juniper / Big Sagebrush Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is known from the Sierra Nevada, ranging from the Lake Tahoe area south to at least Kaiser Pass (southern Sierra). It is primarily an eastside association but is known from the west side from Sonora Pass south. This association is a xeric middle- to high-elevation type. Stands generally range between 2288 and 2593 m (7500-8500 feet) and occur on southeast and southwest aspects. Slopes are commonly less than 30%. It is typically found on upper slopes and ridges. Stress indexes are higher than most other vegetation in the montane zone. This association forms open woodlands with a shrubby understory of Artemisia tridentata. Total vegetative cover is high due to abundant understory species. The principal tree species are Juniperus grandis, Pinus jeffreyi, Pinus contorta; shrubs are Artemisia tridentata, Ribes cereum, Symphoricarpos rotundifolius var. parishii, and Ceanothus cordulatus. Herbs include Monardella odoratissima, Erysimum capitatum var. perenne, Gayophytum eriospermum, and Castilleja applegatei.
