CEGL001854 Carex elynoides - Lupinus argenteus Alpine Turf
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Blackroot Sedge - Silvery Lupine Alpine Turf
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is known from broad, gentle alpine ridges of east-central Idaho. The association occurs on gentle to moderately steep ridgetops. Sites are immediately downwind of windward ridgecrest exposures at 2870-3290 m (9400-10,800 feet) elevation. Seasonal snow accumulation is low. The community is characterized by a short, dense, fibrous-rooted Carex elynoides-dominated turf. Festuca brachyphylla ssp. brachyphylla is a commonly associated grass species. Important herbaceous species include Lupinus argenteus, Phlox pulvinata, Potentilla diversifolia, Minuartia obtusiloba, and Ivesia gordonii. The leeward, concave microtopography of these sites allows greater snow accumulation, compared to the environmentally associated community, Carex elynoides - Oxytropis sericea. Soil disturbance resulting from the burrowing of rodents that utilize winter snow cover gives rise to consistently greater abundance of Lupinus argenteus in this type (CEGL001854) compared to ~Carex elynoides - Oxytropis sericea Alpine Turf (CEGL001856)$$.

Classification Comments: The association is treated by a number of studies that have employed a range of different field methods and analytical techniques within limited portions of the range (Rust 1997a). Carex elynoides alpine turf communities are described for east-central Idaho by Caicco (1983), Moseley (1985), Urbanczyk (1993), Richardson and Henderson (1999), and Cooper et al. (1997).
