Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Arroyo Willow / Woods'' Rose / Mixed Herbs Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This riparian willow shrubland association is reported in north-central Nevada and the Mojave Desert of California. It is also reported from the Blue Mountains, northern Basin and Range, Columbia Basin, and eastern slope of the Cascade Range in Oregon. Sites are on gentle slopes at around 1692 m (5550 feet) elevation with western aspects. The vegetation is characterized by a Salix lasiolepis-dominated, dense tall-shrub canopy with a short-shrub layer (1-2 m tall) codominated by Rosa woodsii and Artemisia tridentata. Other common shrubs include Cornus sericea and Ericameria nauseosa. Clematis ligusticifolia, a vine, is often present. The herbaceous layer is composed of mixed forbs and graminoids such as Hordeum brachyantherum, Leymus cinereus, Phlox longifolia, Polygonum argyrocoleon, and Ranunculus cymbalaria. However, most sampled stands are dominated by the introduced annual grass Bromus tectorum and introduced perennial herb Cirsium vulgare.

Floristics: The vegetation is characterized by a Salix lasiolepis-dominated, dense tall-shrub canopy with a short-shrub layer (1-2 m tall) codominated by Rosa woodsii and Artemisia tridentata. Other common shrubs include Cornus sericea (= Cornus stolonifera) and Ericameria nauseosa. Clematis ligusticifolia, a vine, is often present. The herbaceous layer is composed of mixed forbs and graminoids such as Hordeum brachyantherum, Leymus cinereus, Phlox longifolia, Polygonum argyrocoleon, and Ranunculus cymbalaria.
