Subalpine Ashy Exposed Mountain Slopes 30-45" PZ Cryic Bitterroot Metasedimentary Zone

Description

Vegetation is typically forb-rich, with forbs often contributing more to overall herbaceous cover than graminoids. Tall forb-dominated mesic meadows are typically composed of a wide diversity of genera. At more subalpine elevations, Senecio triangularis, Erigeron peregrinus, Erythronium grandiflorum, Ligusticum species, Veratrum viride and Valeriana species are important forbs. Natural burrowing mammal disturbance regimes can increase forb diversity. Early successional stages may be dominated by Agastache urticifolia, Fragaria virginiana, Urtica dioica, Achillea millefolium, and other forbs, and small amounts of mesic grasses such as Bromus carinatus and Deschampsia cespitosa.
