Common (Translated Scientific) Name: Threetip Sagebrush / Idaho Fescue Shrub Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This description is based on occurrences at Craters of the Moon National Monument and Preserve in Idaho. Additional global information will be added as it becomes available. Throughout the range of this vegetation type, Artemisia tripartita ssp. tripartita dominates the shrub layer and has at least 10% canopy cover. Total vegetation cover can range between 25 and 75%, and is roughly evenly divided between the shrub and herbaceous strata. Festuca idahoensis codominates this association and has a cover of at least 5%. Other shrub species may occasionally be present, but Chrysothamnus viscidiflorus is the only associated shrub species with high constancy. The herbaceous layer is diverse and variable, providing substantial cover. In addition to Festuca idahoensis, associated graminoids generally include, but are not limited to, Poa secunda, Pascopyrum smithii, Pseudoroegneria spicata, and the introduced grass Bromus tectorum. Bromus tectorum is not consistently present but may occur at moderate cover levels where it exists. Forbs are variable and provide sparse cover. Phlox hoodii is the only forb species that is present with high frequency in this association. Sites are gentle to moderately steep colluvial slopes and alluvial benches. Substrates are variable but are typically moderately deep, well-drained soils with sandy clay loam, sandy loam and loam textures. The ground surface has high cover of large and small rocks, low to moderate cover of litter, and occasionally high cover of bare ground.
