CEGL000761 Pinus aristata / Ribes montigenum Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bristlecone Pine / Gooseberry Currant Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is found in northern Arizona, northern New Mexico, and Colorado on scree and cobbly soils from about 3050-3510 m (10,000-11,500 feet) in elevation. Limited plot data suggest that the association is not very species-rich. Pinus aristata is the dominant tree species, and Picea engelmannii is present in low abundance. The shrub layer is dominated by Ribes montigenum with 5-10% canopy cover. Juniperus communis is present but not abundant. Herbaceous species richness is low, and no species has high canopy cover or constancy values among the plots. The greater abundance of Ribes montigenum and the low abundance of Juniperus communis in this association differentiates it from ~Pinus contorta / Juniperus communis Woodland (CEGL000764)$$. The abundance of Trifolium dasyphyllum in ~Pinus aristata / Trifolium dasyphyllum Woodland (CEGL000762)$$ differentiates it from this association (CEGL000761), which has little or no Trifolium dasyphyllum.
Diagnostic Characteristics: Pinus aristata is dominant or is codominant with Picea engelmannii and/or Pinus flexilis in the overstory; and sparse shrubs dominate the understory with Ribes montigenum as the indicator species.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association has been described from data of only a few plots. The greater abundance of Ribes montigenum and low abundance of Juniperus communis in ~Pinus aristata / Ribes montigenum Woodland (CEGL000761)$$ differentiates it from the other Pinus aristata associations.
