CEGL008698 Salix lemmonii Sierran Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Lemmon''s Willow Sierran Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Stands of this shrubland are found in upper montane and subalpine locations throughout the central and southern Sierra Nevada. They usually occur as moderate to large-sized stands but occasionally occupy streamside and lakeshore settings. Stands are found at mid to high elevations (1890-2745 m [6200-9000 feet]) on gentle to somewhat steep south- to southwest-facing slopes (4-47%). This association is often found within mesic portions of meadows where slopes average 3% and range from 0-12%. Occasionally, they are found on streambanks, along shores and in seeps. These sites are typically the bottoms of broad to very broad valleys with shallow uplands slopes and very low valley bottom gradients. These stands generally occur in basins or as stringer meadows with streams present. They usually are adjacent to narrow first-order streams indicative of upper portions of drainages. Microrelief is uniform and gently undulating. Meadows seasonally receive water by subsurface and overland flows from upstream of upslope sources. Some sites are semipermanently flooded, but most are dry at the surface in the summer. Along streams, these stands are seasonally or intermittently flooded, but within seeps water regimes are permanently saturated. Typically they are mesic to wet sites. This association does not appear to be significantly influenced by streamside disturbance. Soils are formed from granitic parent material deposited as alluvium in valley floors. They are often deep but less than 100 cm (40 inches) deep. Surface textures are loams and clays and subsurface textures are sandy clay loams. Drainage is poor to somewhat poor. Stands form a dense, moderately tall shrubland dominated by Salix lemmonii. Most species are obligate and facultative wetland species. Understory species vary, but there is a high constancy of Carex sp., specifically Carex utriculata. Other common species include Mimulus guttatus, Perideridia parishii, Senecio triangularis, Lupinus latifolius, Oreostemma alpigenum, Veratrum californicum, Achillea millefolium, Stachys albens, Viola macloskeyi, and Glyceria striata. This association is often adjacent to Pinus contorta, Abies magnifica, and Pinus jeffreyi forests.

Floristics: Stands form a dense, moderately tall shrubland dominated by Salix lemmonii. Most species in this stand are obligate and facultative wetland species. Understory species vary, but there is a high constancy of Carex sp. specifically Carex utriculata. Other common species include Mimulus guttatus, Perideridia parishii, Senecio triangularis, Lupinus latifolius, Oreostemma alpigenum (= Aster alpigenus), Veratrum californicum, Achillea millefolium, Stachys albens, Viola macloskeyi, and Glyceria striata (= Glyceria elata) (Potter 2000). Common herbs found at Yosemite include Phleum alpinum, Potentilla gracilis, Allium validum, Epilobium ciliatum, Juncus drummondii, Polygonum bistortoides, Thalictrum fendleri, and Veronica wormskjoldii. Carex amplectens, Calamagrostis canadensis, Carex utriculata, Perideridia parishii, and Poa pratensis. Other species contributing to minor cover may include Aconitum columbianum, Arnica mollis, Symphyotrichum foliaceum var. apricum (= Aster foliaceus var. apricus), Carex heteroneura var. heteroneura, Lupinus polyphyllus, Mimulus guttatus, moss, Platanthera dilatata var. leucostachys (= Platanthera leucostachys), Senecio triangularis, and Trifolium monanthum. This association is often adjacent to Pinus contorta, Abies magnifica, and Pinus jeffreyi forests (Potter 2000).
