CEGL000808 Pinus flexilis / Juniperus osteosperma Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Limber Pine / Utah Juniper Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland association occurs in the Pryor Mountains of south-central Montana and may also occur in adjacent Wyoming. Stands are locally common on mid to upper slopes and benches between 1310-1615 m (4300-5300 feet) elevation. This type occurs on shallow soils, derived from calcareous sandstone with a pH >7.5. Ground cover is largely gravel and rock, often exceeding 70%, with over 10% cover of bare soil. The open overstory canopy includes a low cover of Pinus flexilis and Juniperus osteosperma. The undergrowth is characterized by a sparse short-shrub layer of Artemisia nova, Gutierrezia sarothrae, and Petrophytum caespitosum; the perennial bunchgrass Pseudoroegneria spicata; and the cactus, Opuntia polyacantha.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is based on 10 plots from the Pryor Mountains described by DeVelice and Lesica (1993), and has not been found elsewhere. Survey of similar habitats in the Bighorn Mountains in Wyoming may locate new stands.
