CEGL001964 Geum rossii Alpine Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Ross'' Avens Alpine Meadow
Colloquial Name: Ross'' Avens Dry Alpine Meadow
Hierarchy Level: Association
Type Concept: This alpine meadow association occurs in the mountains of Idaho, Wyoming, Colorado, Utah and Nevada. This description is based on information from Great Sand Dunes National Park and Preserve in Colorado. Additional global information will be added as it becomes available. This association occurs in cirque and valley floors, high colluvial slopes, and along ridgelines. The elevation ranges from 3700 to 3835 m on predominantly northwest-facing slopes. Slopes are generally steep and very rocky. Soils are well-drained and sandy loam or silt loam in texture. Ground surface cover can be variable with bare soil, litter and duff, gravel, rock, bedrock, and mosses. The herbaceous layer dominates this association with Geum rossii var. turbinatum ranging in cover from 20 to 50%. Artemisia scopulorum is also found within the majority of sites surveyed with up to 10% cover. Carices are present within all of the sampled sites with a wide variety of species including Carex heteroneura, Carex haydeniana, Carex elynoides, Carex microptera, Carex siccata, and Carex albonigra.
