Common (Translated Scientific) Name: Utah Juniper - (Singleleaf Pinyon) / Desert Ceanothus Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This pinyon-juniper woodland association is currently described from Grand Canyon-Parashant National Monument Arizona. More survey and classification work are needed to fully characterize this type. It occurs at 1800 to 2050 m (5890-6700 feet) elevation on gently sloping (1-9°) sideslopes and high-level plateaus. It seems to often favor north-facing aspects, but can also occur on east- and south-facing slopes as well. Soils tend to be moderately to well-drained clay silt loams that are typically derived from basalt or limestone parent materials. The tree canopy is comprised primarily of Juniperus osteosperma with some occasional Pinus monophylla. Many stands support a sparse subcanopy consisting mostly of Juniperus osteosperma. Ceanothus greggii is the characteristic shrub species in this association, and Artemisia tridentata also occurs in most stands at low cover. Various other shrub species, such as Cylindropuntia whipplei, Quercus gambelii, Purshia stansburiana, and Gutierrezia sarothrae, frequently occur. Bouteloua gracilis, Poa fendleriana, Elymus elymoides, and Bouteloua curtipendula are the dominant grasses in a sparse herbaceous understory. Penstemon linarioides, Camissonia sp., Eriogonum umbellatum, and Hymenoxys richardsonii are common forb species. This association can occur over large areas, often as part of an extensive network of various Juniperus osteosperma - Pinus monophylla vegetation types.
