CEGL001216 Salix lasiolepis / Barren Ground Wet Shrubland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Arroyo Willow / Barren Ground Wet Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This plant association typically occurs in narrow valley bottoms throughout Nevada, in southern Utah, southwestern Idaho, and southeastern California. Stands occur on stream benches (channel bars that have become elevated due to sediment accumulation), as stringers along moderate gradient channels, and occasionally around sloping springs. Salix lasiolepis creates a dense overstory. Ribes aureum and Rosa woodsii are sometimes present with low cover. Herbaceous undergrowth is sparse due to shading, xeric soil conditions, or possibly grazing pressure and no species has high cover or constancy.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: The classification of this association is based on data from southern Utah (Padgett et al. 1989), Nevada (Manning and Padgett 1995), and southwestern Idaho (Moseley 1998, Moseley et al. 1998). Species composition and soils are similar in all classifications. It is less clear whether or not landforms are equivalent.
