CEGL001238 Salix wolfii / Deschampsia cespitosa Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Wolf''s Willow / Tufted Hairgrass Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a minor plant association with a widespread distribution including mid to upper elevations throughout the Rocky Mountains. The association is found in meadows, on lower toeslopes, and on benches or terraces in broad valley bottoms. Salix wolfii creates a dense, low overstory with Dasiphora fruticosa ssp. floribunda frequently present. Deschampsia cespitosa is the diagnostic graminoid with up to 10% cover. A diverse mix of other graminoids and forbs are usually present, including Juncus arcticus ssp. littoralis, Danthonia intermedia, Phleum alpinum, Potentilla gracilis, and Senecio integerrimus.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This plant association has been described in numerous classifications. The difficulty in classification comes when stands are disturbed and the diagnostic understory species Deschampsia cespitosa is only present with low cover and exotic grasses dominate the stand.

Physiognomy and Structure: No Data Available
Floristics: These shrublands have an open canopy and low stature dominated by Salix wolfii. Other shrubs present include Dasiphora fruticosa ssp. floribunda, Vaccinium cespitosum, Arctostaphylos uva-ursi, Betula nana, and various Salix spp. The herbaceous layer is dominated by Deschampsia cespitosa; however, degraded stands may have low cover of this diagnostic species. Other graminoids that may be present include Phleum pratense, Juncus arcticus ssp. littoralis (= Juncus balticus), Danthonia intermedia, Agrostis stolonifera, Carex utriculata, Carex microptera, Carex praegracilis, and Carex aquatilis. Forbs can be abundant and include Fragaria virginiana, Valeriana edulis, Angelica arguta, Taraxacum officinale, Achillea millefolium var. occidentalis, Antennaria spp., Caltha leptosepala var. leptosepala, Erigeron spp., Fragaria virginiana ssp. glauca, Gentiana parryi, Penstemon procerus var. procerus, Potentilla diversifolia, Sibbaldia procumbens, Solidago spp., Stellaria longipes, Taraxacum officinale, Noccaea fendleri ssp. glauca (= Thlaspi montanum var. montanum), and Veronica wormskjoldii.
Dynamics: No Data Available
Environmental Description: This association occurs from 2000 to 3100 m (6550-10,170 feet) in elevation, usually on broad valley bottoms. Soils are fine-textured and highly erodible. Soils range from sandy loam to clayey. Nearly all studies report mottling or a gleyed layer between 40 and 99 cm depth.
Geographic Range: This is a minor type in Utah, Wyoming, Idaho and Montana.
