CEGL001495 Purshia tridentata / Pseudoroegneria spicata Shrub Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Antelope Bitterbrush / Bluebunch Wheatgrass Shrub Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This plant association is described from sites in the Eastern Cascades, Blue Mountains, and Bitterroot Valley ecoregional sections. Stands are also reported from the southwestern portion of the Idaho Batholith section. The association occurs on steep, south-facing, mid to upper slopes at 580 to 1680 m (1900-5500 feet) elevation (typically at higher elevation in the eastern portion of the range). Soils are typically dry, shallow, and rocky. A high exposure of rock and surface soil is common. Relatively open stands of Purshia tridentata occur with Pseudoroegneria spicata and Balsamorhiza sagittata. Poa secunda and Lomatium dissectum are often also present.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The association is described as a classification of natural potential vegetation by Daubenmire (1970), Johnson and Simon (1987), and Mueggler and Stewart (1980). Hall (1973) did not differentiate sites with the potential for Festuca idahoensis.
