Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Basin Wildrye Bottomland Wet Meadow
Colloquial Name: Basin Wildrye Bottomland Wet Meadow
Hierarchy Level: Association
Type Concept: This is a herbaceous, alkali meadow community dominated by Leymus cinereus. This association is found in alkali meadows throughout the Great Basin and arid portions of California between 1220 and 2900 m (4000-9500 feet) elevation. It is restricted to saline, permanently saturated bottomlands or the lower portions of alluvial slopes between 1400-3000 m elevation. Leymus cinereus is the sole or dominant grass in the herbaceous layer. Pseudoroegneria spicata, Bromus tectorum, Achnatherum hymenoides, Koeleria macrantha, Poa secunda, Hesperostipa comata, Achnatherum thurberianum, and/or Pascopyrum smithii may be present. Emergent shrubs may be present. Grasses are <1.5 m, and cover is open.
