Name: Juncus drummondii - Carex spp. Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This plant association occurs at subalpine and alpine elevations in the Rocky Mountains. In alpine areas they occur on solifluction terraces where soil moisture is abundant and snow duration is 8.5 to 11 months. In the lower elevations associations are found in lush wet meadows, seeps on slopes, and adjacent to streams and ponds. It is also found on rocky, inclined (2-10% slope), southeast-oriented sites which are subxeric to mesic. Substrates are variable and range from skeletal soils with coarse fragments to loamy soils. Cover of small and large rocks and boulders may be low to highly significant with up to 50% soil surface. The vegetation is characterized by a moderately dense to dense herbaceous layer dominated by <i>Juncus drummondii</i> and by species of <i>Carex</i>. Common graminoids include <i>Carex nigricans, Carex pyrenaica</i> in the alpine stands; <i>Carex spectabilis(= Carex tolmiei), Deschampsia caespitosa, Hordeum brachyantherum</i>, and <i>Muhlenbergia richardsonis</i> in the lower elevations. The forb layer is typically sparser than the graminoid layer but may codominate. Species may include <i>Antennaria alpina, Caltha leptosepala, Epilobium anagallidifolium, Erigeron melanocephalus, Ligusticum filicinum</i>, and <i>Sibbaldia procumbens</i>. Typical forbs from lower elevations include <i>Polygonum bistortoides, Iris missouriensis</i>, and <i>Machaeranthera bigelovii (= Aster rubrotinctus)</i>. In the more xeric stands a moss layer dominated by <i>Polytrichum piliferum</i> can be present.  Accession Code: VB.CC.33813.CEGL001905 Plot-observations of this Community Concept: 0
