CEGL000593 Populus tremuloides / Lupinus argenteus Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Quaking Aspen / Silvery Lupine Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland type is found in small stands in the montane zone of the Bighorn Mountains of north-central Wyoming. Stands have been described from a variety of aspects at 2134 to 2365 m (7000-7760 feet) elevation. The vegetation has a simple structure, with an overstory of Populus tremuloides and a species-rich herbaceous usually dominated by Taraxacum officinale, Lupinus argenteus, and Trifolium sp., and containing Festuca idahoensis, Leucopoa kingii, Poa nervosa, and Achillea millefolium. Most stands are heavily grazed by livestock.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The validity of this type is uncertain. It has been described from four stands of the Populus tremuloides / Lupinus argenteus habitat type (Hoffman and Alexander 1976), and those four stands are dominated by exotic species, apparently at least partly as a result of heavy grazing by livestock. Native understory species with high constancy or substantial cover are Lupinus argenteus, Achillea millefolium, Festuca idahoensis, Leucopoa kingii, and Poa nervosa. The vegetation seems to resemble the Populus tremuloides / Stipa comata community type from Idaho and Utah (Mueggler 1988) more closely than it does any other association. Also compare ~Populus tremuloides / Juniperus communis / Lupinus argenteus Forest (CEGL000589)$$.
