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. Artemisia tridentata ssp. tridentata dominates the shrub layer of the plant communities in this association. Total vegetation cover is low to moderate and tends to be higher in the shrub stratum than in the herbaceous stratum. Festuca idahoensis is abundant in the understory and may occasionally codominate this association. Other shrub species are occasionally present and may include Chrysothamnus viscidiflorus, Purshia tridentata, and other Artemisia tridentata subspecies. The herbaceous layer is diverse and variable, providing low to moderate cover. In addition to Festuca idahoensis, associated graminoids generally include, but are not limited to, Pseudoroegneria spicata, Poa secunda, and the introduced grass Bromus tectorum, which typically occurs at relatively low cover. Forbs are variable, provide sparse cover, and may include Allium spp., Crepis acuminata, Delphinium spp., and Phlox spp. Sites supporting is shrubland may include sloping fans, footslopes, rolling hills, and deep, well-drained alluvial bottomlands. Soils are deep, fine- to medium-textured alluvial soils with some source of subirrigation during the summer season, but moderately deep upland soils with ample moisture storage also support these shrublands. The range of this shrubland association is likely further constrained by the environmental requirements of Festuca idahoensis.
