Name: Carex elynoides - Oxytropis sericea Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This plant association is known from broad, gentle alpine ridges of east-central Idaho. The association occurs on gentle to moderately steep ridgetops. Sites occur on windward ridgecrest exposures at 2870-3290 m (9400-10,800 feet) elevation. The association occurs on convex microtopographical features. Seasonal snow accumulation is low. Sites are frequently blown snow-free in winter. The community is characterized by a short, dense, fibrous-rooted <i>Carex elynoides</i>-dominated turf. <i>Poa secunda</i> and <i>Poa glauca ssp. rupicola</i> are commonly associated grass species. Important herbaceous species include <i>Oxytropis sericea, Phlox pulvinata, Potentilla diversifolia, Agoseris glauca</i>, and <i>Eritrichium nanum</i>. A similar association, ~<i>Carex elynoides - Lupinus argenteus</i> Herbaceous Vegetation (CEGL001854)$$, occurs on adjacent downwind sites. Concave microtopography of <i>Carex elynoides - Lupinus argenteus</i> sites appears to allow greater snow accumulation. Soil disturbance resulting from the burrowing of rodents that utilize this winter snow cover gives rise to consistently greater abundance of <i>Lupinus argenteus</i> in <i>Carex elynoides - Lupinus argenteus</i> compared to <i>Carex elynoides - Oxytropis sericea</i>.
