CEGL003142 Juncus parryi - Phyllodoce breweri Alpine Snowbed
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Parry''s Rush - Purple Mountain-heath Alpine Snowbed
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This herbaceous association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this alpine shrub/grassland association are found at about 3110 m (10,200 feet) of elevation on moderate to steep midslopes. Aspects are east, and soils are well-drained silt loams derived from metamorphic parent material. Sites are fairly stony and tend to accumulate deep snowpacks that persist until about late July. Based on limited quantitative data for this description, this association is characterized by an open canopy of Phyllodoce breweri over a graminoid/forb layer. Canopy height is less than 0.5 m. Scattered emergent individuals of Pinus albicaulis may be present. Carex exserta is the dominant graminoid, but Juncus parryi is diagnostic. Traces of other graminoids may be present including Achnatherum nevadense, Elymus elymoides, and/or Poa secunda. Forbs are scattered and sparse with Antennaria rosea attaining the most cover at 2.5%. Traces of the forbs Arabis platysperma, Monardella odoratissima, and/or Penstemon heterodoxus may be present.
