Name: Carex elynoides - Lupinus argenteus Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: 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 <i>Carex elynoides</i>-dominated turf. <i>Festuca brachyphylla ssp. brachyphylla</i> is a commonly associated grass species. Important herbaceous species include <i>Lupinus argenteus, Phlox pulvinata, Potentilla diversifolia, Minuartia obtusiloba</i>, and <i>Ivesia gordonii</i>. The leeward, concave microtopography of these sites allows greater snow accumulation, compared to the environmentally associated community, <i>Carex elynoides - Oxytropis sericea</i>. Soil disturbance resulting from the burrowing of rodents that utilize 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> Herbaceous Vegetation (CEGL001856)$$.
