Name:
Antennaria lanata - Juncus parryi Alpine Meadow Alliance
Reference:
NatureServe Biotics 2019
Description:
This vegetation is characterized by a ground layer of <i>Antennaria lanata</i> and/or <i>Juncus parryi</i>, herbaceous perennials less than 30 cm in height. Regardless of dominance, the associated herbaceous species are very similar and include <i>Arenaria capillaris, Carex breweri, Carex nigricans, Carex phaeocephala, Carex scirpoidea, Carex spectabilis, Festuca brachyphylla, Hieracium gracile, Juncus drummondii, Luetkea pectinata, Lupinus arcticus ssp. subalpinus, Lupinus latifolius, Luzula piperi, Luzula spicata, Minuartia obtusiloba, Oreostemma alpigenum, Polygonum bistortoides</i>, and <i>Sibbaldia procumbens</i>. <i>Cassiope mertensiana, Phyllodoce empetriformis</i>, and <i>Salix cascadensis</i> may form a very sparse shrub layer. Lichens and bryophyte species are often abundant, including <i>Cetraria islandica, Cladonia pyxidata, Lepraria neglecta, Polytrichum juniperinum</i>, and <i>Polytrichum piliferum</i>. This alliance occurs in snowmelt basins and subalpine meadows of the Cascade Range at 1800-2200 m elevation. These habitats receive abundant precipitation (100-250 cm) and accumulate very heavy snowpacks in winter. These sites are subirrigated by snowmelt during most of the short growing season.
