Name: Alnus incana / Scirpus microcarpus Shrubland Reference: Western Ecology Working Group of... Description: This association is recognized as a minor shrub-fen Alnus incana ssp. tenuifolia type that appears in the Thompson-Okanogan Plateau of Washington and in the Blue Mountains of Oregon. Washington samples are located between 845-945 m (2800-3100 feet) elevation in broad, low-gradient valleys along meandering streams or in shrub wetlands. Oregon stands are found at higher elevations located between 1220 and 1586 m (4000-5200 feet). These sites can occur where lots of deposition occurs on floodplains under alder or where sands and gravels have been dumped into an Alnus incana wetland. Soils are typically organic with a shallow water table and often with some exposed surface water. This association has the highest average cover of Alnus incana ssp. tenuifolia in 16 Alnus incana ssp. tenuifolia types on the national forests of eastern Washington. Cornus sericea and Salix bebbiana are frequent shrubs that occur with very low cover in this community. The herbaceous layer contains wet-site graminoids and forbs and is dominated by Scirpus microcarpus (well over 20% cover). Common herbaceous species, whose combined cover is typically much less than Scirpus microcarpus, include Glyceria striata (= Glyceria elata), Carex utriculata, Equisetum arvense, Epilobium ciliatum ssp. watsonii, and Veronica americana.  Accession Code: VB.CC.20626.ALNUSINCANASCIR Plot-observations of this Community Concept: 0
