CEGL001668 Pseudoroegneria spicata - Eriogonum heracleoides Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bluebunch Wheatgrass - Parsnip-flower Buckwheat Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is described from stands located in the upper Hells Canyon region. Similar stands are located in the Seven Devils and eastern Salmon River mountains. The association occurs on moderately steep to steep, southeast- to southwest-facing, mid to upper slopes at 1310 to 1710 m (4300-5600 feet) elevation. Soils are derived from basalt rock and colluvium. Pseudoroegneria spicata - Eriogonum heracleoides is the highest elevation Pseudoroegneria spicata-dominated plant association. Eriogonum heracleoides is well-represented in the open bunchgrass stands. Melica bulbosa is often present. Consistently associated forbs are Achillea millefolium, Frasera albicaulis, Penstemon venustus, and Lupinus caudatus. Sites are more moist and cool compared to other Pseudoroegneria spicata-dominated habitats. High-elevation Festuca idahoensis - Pseudoroegneria spicata communities are often adjacent.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Though the association is well documented within the Hells Canyon region (Johnson and Simon 1987), data presented by Mueggler and Harris (1969) suggest the association has not been documented throughout the entire extent of the expected range.

Floristics: Pseudoroegneria spicata dominates and Eriogonum heracleoides is well-represented in the open bunchgrass stands. Melica bulbosa is often present. Consistently associated forbs are Achillea millefolium, Frasera albicaulis, Penstemon venustus, and Lupinus caudatus.

Environmental Description: The association occurs on moderately steep to steep, southeast- to southwest-facing, mid to upper slopes at 1310 to 1710 m (4300-5600 feet) elevation. Soils are derived from basalt rock and colluvium. Pseudoroegneria spicata - Eriogonum heracleoides is the highest elevation Pseudoroegneria spicata-dominated plant association. Sites are more moist and cool compared to other Pseudoroegneria spicata-dominated habitats.
Geographic Range: The association occurs in a cluster of stands located in the southeastern Wallowa Mountains (Johnson and Simon 1987), and a few isolated, dispersed stands are tentatively identified for the central Idaho Batholith and southern Bitterroot Mountains ecoregional sections and within the Seven Devils Mountains (unpublished data, Idaho Conservation Data Center, Mueggler and Harris 1969).
