Name: Alnus incana / Symphoricarpos albus Wet Shrubland Reference: NatureServe Biotics 2019 Description: This association is known from around the rim of the northwestern end of the Columbia Plateau in western Middle Rocky Mountains, southern Okanogan Plateau, and lower flank of the East Cascades. This association is found between 518-1678 m (1700-5500 feet) elevation typically along streams, although it is also associated with lakes and wetlands. Soils are fine-textured soil over coarse material and remain moist through the growing season. Sites where it is found are flooded during peak runoff and dry below 60 cm (2 feet) late in the growing season. This type is found within montane coniferous forest landscapes but may extend down into transition shrub-steppe zones. This is a 3- to 6-m (10-20 feet) tall riparian shrub thicket dominated by <i>Alnus incana ssp. tenuifolia</i> with occasional but never abundant <i>Cornus sericea</i>. These tall shrubs appear over a less than 2-m tall <i>Symphoricarpos albus</i> shrub layer often with <i>Rosa</i> and <i>Ribes</i> species. The herbaceous layer is typically sparse, containing a wide range of both graminoid and forb species, only few with high constancy, for example, <i>Galium triflorum</i> and <i>Geum macrophyllum</i>. This is the driest of the <i>Alnus incana</i> shrublands known from the northern Rockies and Columbia Basin.  Accession Code: urn:lsid:vegbank.org:commConcept:30062-{1561D04B-D8E0-43BC-9E74-3736976B1465} Plot-observations of this Community Concept: 0
