Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Thick-spike Wheatgrass - Silvery Lupine Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: These sparse grasslands are dominated by Elymus lanceolatus, which is a cool-season, rhizomatous perennial grass. Total cover rarely exceeds 20%. Additional grass species that occur with high constancy but low cover include Leymus cinereus, Pseudoroegneria spicata, and the introduced annual grass Bromus tectorum. Very scattered patches of 1- to 2-m tall shrubs are occasionally present and include Artemisia tridentata and Chrysothamnus viscidiflorus. Lupinus argenteus is characteristic of this plant community although it often occurs with very low cover. Several other forb species also tend to be constant but sparse in this vegetation type. They include Allium acuminatum, Crepis acuminata, Lomatium triternatum, and Phlox longifolia. Sites are flat to gentle slopes with dry, deep loess or sandy soils. This association is often found in a patchwork with sand dunes and dune shrublands. Summers are typically hot and dry, with most precipitation falling during October through May.

Classification Comments: This plant community description is based on data from Craters of the Moon (Bell et al. 2009) and on related plant communities that have been previously described. The description provided herein may vary slightly from similar plant communities found elsewhere due to the local scale at which data were collected. Additional global information will be added as it becomes available.
This association is uncommon at Craters of the Moon National Monument and Preserve. Due to the limited spatial extent of occurrence and associated low sample size, the classification of this plant community is considered provisional. Consequently, the characteristic species list for this association at Craters of the Moon is also limited.
