Hierarchy Level:  Association

Type Concept: This lower-elevation woodland association has only been described from Bandelier National Monument in north-central New Mexico. The current description is based on data received from there and will be updated when additional inventory data are available. This association occurs between 1820 and 1970 m (5960-6470 feet) elevation on northeasterly through southeasterly to southwesterly aspects with moderate solar exposure. Sites vary from moderately steep (22%) shoulders of plateaus to steep (50%) canyon escarpment sideslopes. Stands typically occur on shallow, often rocky soils or rock outcrops derived from soft rhyolitic tuff parent material or sandstone. Hence, ground surfaces are mainly dominated by rock, cobbles, and gravel with scattered litter and bunchgrasses. This short-statured coniferous woodland varies from very open (20% canopy cover) to partially closed-canopied stands (50%) dominated by Juniperus monosperma. Other mature trees species are accidental or absent, but scattered Pinus edulis seedlings and saplings can occur. Understories are typically sparsely vegetated. While shrubs can be common, they seldom exceed 5% cover and usually include deciduous Cercocarpus montanus and Quercus x pauciloba, rosetophyllous Yucca baccata, and the succulents Opuntia polyacantha, Opuntia phaeacantha, and Cylindropuntia imbricata. The herbaceous layer is poorly represented and characterized by scattered grasses and forbs among the rocks and boulders. Among the 20 herbs reported for the association, Bouteloua curtipendula, Bouteloua gracilis, and Bahia dissecta are the most frequent.
