Reference: EcoArt 2002
Description: This alliance occurs in the alpine tundra in the mountains of Colorado. Stands are found in a wide altitudinal range between 3320 and 3760 m elevation on wet sites along streamlets. Soils have a large percentage of organic matter, primarily partially decomposed plant material, and are saturated with water for most of the year. The soil profile has only one horizon. The vegetation in the alliance occurs in small stands on permanently wet sites. ~Rhodiola rhodantha (= Sedum rhodanthum)$ and ~Rhodiola integrifolia (= Sedum integrifolium)$ dominate the herbaceous canopy. ~Carex capillaris, Juncus triglumis$, and ~Poa arctica$ are common associates. The moss layer has a moderate to dense cover. A number of moss species are present, including ~Bryum turbinatum, Calliergon stramineum, Drepanocladus aduncus, Grimmia mollis (= Hydrogrimmia mollis)$, and ~Polytrichastrum alpinum$.
