This alliance occurs in the alpine tundra on windblown summits and ridges in the mountains of central Colorado. Stands are found above 3900 m on cold, dry microsites in rock crevices and on outcrop ledges primarily on southwest-facing slopes. Soils are young and poorly developed due to low soil temperature, low soil moisture during the summer, and a short growing season. The majority of the ground surface is covered with rock. ~Claytonia megarhiza$ is the dominant species. ~Draba fladnizensis, Draba lonchocarpa, Sagina saginoides, Silene acaulis, Festuca brachyphylla, Poa alpina$, and ~Poa lettermanii$ are common associates. A cryptogam layer is present with ~Hypnum revolutum, Bryoerythrophyllum recurvirostre$, and ~Physcia musigena$ the most constant species. |

Phlox diffusa Herbaceous Alliance

accession code: VB.CC.24187.PHLOXDIFFUSAHER

This alliance occurs on somewhat xeric alpine sites in the mountains of the Pacific Northwest, between 1800 and 2400 m in elevation. These communities typically occur at sites where snowmelt occurs early and plants are exposed to frequent freezing and thawing in the spring. Frost heaving is common and may result in striped patterns of bare substrate and vegetation perpendicular to the mountain slopes. Soils are typically skeletal and excessively drained. These communities are dominated by Phlox diffusa, which forms scattered mats of vegetation less than 20 cm high. Associated species include other mat-formers such as Arenaria capillaris, Eriogonum pyrolifolium, Douglasia laevigata, and Paxistima myrsinites. Paxistima is a taller shrub at lower altitudes, but is a prostrate dwarf-shrub in these habitats. Other herbaceous species include Arabis cobrensis, Collinsia parviflora, Carex spectabilis, Penstemon procerus, Erigeron aureus, Lupinus lepidus, and Antennaria alpina. |
