G624 Western North American Interior Ruderal Grassland & Shrubland Group
Type Concept Sentence: This group includes grasslands dominated by the non-native grass Elymus repens and is known from disturbed valley bottoms, alluvial flats, fans and lower valley wall sites in western Colorado and northwestern Montana.
Common (Translated Scientific) Name: Western North American Interior Ruderal Grassland & Shrubland Group
Colloquial Name: Western North American Interior Ruderal Grassland & Shrubland
Hierarchy Level: Group
Type Concept: This montane, mesic to subhygric herbaceous group has low overall species diversity due to the dominance of Elymus repens, an exotic rhizomatous grass. Elymus repens is a highly invasive species in mesic areas and tends to exclude other species once established. Overall herbaceous cover ranges from 25-85% with Elymus repens clearly dominating with 5-80% cover. This group occurs in western Colorado, northwestern Montana, and southern Idaho. Sites include disturbed valley bottoms, alluvial flats, fans and lower valley wall sites between 1450 and 2300 m in elevation.
