CEGL002069 Salix lemmonii / Mesic Graminoids Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Lemmon''s Willow / Mesic Graminoids Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This riparian shrubland occurs in the Sierra Nevada, Carson and Sweetwater ranges of western Nevada, the Wildhorse Range of northern Nevada, and in the Teton Range of western Wyoming. Elevation ranges from 2045-2660 m (6700-8720 feet). It occurs on stream terraces, benches or on seeps in narrow to wide valleys, on low- to moderate-gradient slopes. Stream channels are often wide and only slightly sinuous. This is a tall willow shrubland dominated by Salix lemmonii. Other shrubs present include Salix geyeriana and Salix lutea intermixed in the upper canopy, with Ribes inerme occasionally occurring as a sub-shrub canopy. The herbaceous undergrowth is moderate to dense with several graminoid species; none are singly dominant, but graminoid cover is greater than that of any forbs present. Typical graminoid species are Carex pellita, Carex nebrascensis, Carex simulata, Carex hoodii, Poa pratensis, and/or Calamagrostis canadensis. Forbs, when present, are sparse or low-growing species not visible due to the dense graminoid cover. Forb species in Nevada indicate moist surface conditions and include Mimulus guttatus, Mentha arvensis, Polemonium caeruleum, and Cardamine spp. In Wyoming, sampled stands were disturbed from grazing and had dry-condition indicator forb species present such as Eriogonum umbellatum, Achillea millefolium, Potentilla pulcherrima, and Symphyotrichum ascendens.

Floristics: This is a tall willow shrubland dominated by Salix lemmonii. Other shrubs present include Salix geyeriana and Salix lutea intermixed in the upper canopy, with Ribes inerme occasionally occurring as a sub-shrub canopy. The herbaceous undergrowth is moderate to dense with several graminoid species; none are singly dominant, but graminoid cover is greater than that of any forbs present. Typical graminoid species are Carex pellita (= Carex lanuginosa), Carex nebrascensis, Carex simulata, Carex hoodii, Poa pratensis, and/or Calamagrostis canadensis. Forbs, when present, are sparse or low-growing species not visible due to the dense graminoid cover. Forb species in Nevada indicate moist surface conditions and include Mimulus guttatus, Mentha arvensis, Polemonium caeruleum, and Cardamine spp. In Wyoming, sampled stands were disturbed from grazing and had dry-condition indicator forb species present such as Eriogonum umbellatum, Achillea millefolium, Potentilla pulcherrima, and Symphyotrichum ascendens.

Environmental Description: Elevation ranges from 2045-2660 m (6700-8720 feet). This association occurs on stream terraces, benches or on seeps in narrow to wide valleys, on low- to moderate-gradient slopes. Stream channels are often wide and only slightly sinuous (Rosgen Channel Type: B2 or B4). Soils are Cumulic Haploxerolls and Aquic Cryoborolls, with up to 70% gravel content. The water table is well below 1 meter of the soil surface.
Geographic Range: This riparian shrubland occurs in the Sierra Nevada, Carson and Sweetwater ranges of western Nevada, the Wildhorse Range of northern Nevada, and in the Teton Range of western Wyoming.
