CEGL001980 Phlox pulvinata - Trifolium dasyphyllum Alpine Fell-field
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Cushion Phlox - Alpine Clover Alpine Fell-field
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This alpine cushion-plant vegetation association has been named from Carter Mountain on the eastern side of the Absaroka Mountains in northwestern Wyoming. Stands of this type occur on moderately steep slopes in the lee of ridgetops. Soils are loamy to sandy loam in texture, moderately deep, stony throughout, and provide less water than soils on other topographic positions in the area. The vegetation, as described by standing crop rather than cover, consists mainly of Phlox pulvinata and Trifolium dasyphyllum, with Artemisia scopulorum, Lomatium cous, Oxytropis parryi, Phlox multiflora, and Arenaria congesta as common species. Graminoids (mainly Poa spp., Koeleria macrantha, Carex elynoides, and Carex obtusata) produce less standing crop than do the cushion forbs.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is based on measurements of standing crop and descriptions of soils in 4 stands on Carter Mountain. Virtually nothing else is known about this type. More information might show that it is best considered merely a patch in a larger alpine vegetation type, rather than a distinct association.
