Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Twin-flower Sandwort Alpine Fell-field
Colloquial Name: Sandwort Alpine Fell-field
Hierarchy Level: Association
Type Concept: This alpine fell-field herbaceous association occurs in the Rocky Mountains of Colorado and New Mexico. 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 can occur on mid- to high-slope ridges, drainage channels, colluvial slopes, interfluves, and saddles. Elevation ranges from 3475 to 3875 m with southeast-, southwest-, and west-facing slopes that can range from 0-30°. Sites are generally rocky with rock (0-40%) and gravel (3-60%). Soils are well-drained sandy loams or somewhat poorly drained loams. In general, the presence of deer, sheep, and pika grazing was observed. The total herbaceous layer cover ranges from 10-60%, with 10-20% graminoid cover and 10-60% forb cover. Dominant graminoid Carex elynoides has up to 20% cover. Other common graminoids at low cover include Festuca brachyphylla and Trisetum spicatum. Dominant forbs at low cover include Minuartia obtusiloba, Silene acaulis var. subacaulescens, Geum rossii var. turbinatum, and Trifolium dasyphyllum.
