CEGL000810 Pinus flexilis / Leucopoa kingii Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Limber Pine / Spike Fescue Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland association is present on dry slopes of various aspects and ridgetops between 1585 and 2990 m (5200-9800 feet) elevation throughout the mountains of western and southern Wyoming and north-central Colorado. It is an incidental type in east-central Idaho, found bordering nonforested communities between 2380 and 2685 m (7800-8800 feet) elevation on severe, windy, south-facing slopes. It is also described as an incidental type in extreme southern Montana. Stands are frequently observed as linear strips located between drier nonforested communities and more moist sites of Pseudotsuga, Abies, and Picea on steep slopes of coarse limestone and sandstone soils. The average litter depth is less than 7.62 cm (3 inches). Soils are usually calcareous with a moderate to high percentage of bare soil and rock. Stands are dominated by an open canopy of widely spaced Pinus flexilis with various amounts of Pseudotsuga menziesii. Shrubs that are frequently present but have low coverage include Artemisia tridentata, Ribes cereum, and Symphoricarpos oreophilus. The understory is usually codominated by bunchgrasses Leucopoa kingii and Pseudoroegneria spicata ssp. spicata. Other herbaceus vegetation includes Astragalus miser, Balsamorhiza sagittata, Carex rossii, and Crepis acuminata.

Classification Comments: This association should be compared to ~Pinus flexilis / Mahonia repens Woodland (CEGL000811)$$ in Utah. ~Pinus flexilis / Pseudoroegneria spicata Woodland (CEGL000813)$$ is similar to this association and is widely distributed east of the Continental Divide. In the Beaverhead National Forest, Montana, it is found between 1341 and 2012 m (4400-6600 feet) elevation in similar soils of limestone and sandstone.

Geographic Range: This woodland association is present throughout western Wyoming (Absaroka and Wind River ranges) and in southeastern Wyoming and north-central Colorado in the Medicine Bow Range. In east-central Idaho it is found in the southern end of the Lemhi and Beaverhead ranges. It is also described as an incidental type in extreme southern Montana.
