Name: Alnus incana - Salix drummondiana Wet Shrubland Reference: NatureServe Biotics 2019 Description: This riparian shrubland association is common in mountains of Colorado and western Wyoming and likely occurs in adjacent New Mexico. Stands are generally found along steep-gradient streams between 2038 and 3000 m (6686-9835 feet) elevation. It is an early- to mid-seral community restricted to stream margins, alluvial surfaces, and coarse-textured cobble bars, rarely forming large or extensive stands. The vegetation is characterized by a dense, closed, tall-shrub canopy of 10-100% cover of <i>Alnus incana ssp. tenuifolia</i> and 10-60% cover of <i>Salix drummondiana</i>. Other shrubs occurring with greater than 25% frequency include <i>Salix monticola, Lonicera involucrata, Ribes inerme, Cornus sericea, Rosa woodsii</i>, and <i>Amelanchier utahensis</i>. Tree cover ranges from 0-20% dominated by <i>Picea pungens</i> (0-10%) and <i>Picea engelmannii</i> (0-23%). In some stands, heavy shading and recent flood scouring limit herbaceous growth (&lt;10%). Other stands have a rich herbaceous understory that includes <i>Heracleum maximum, Equisetum pratense, Rudbeckia laciniata</i>, and <i>Angelica ampla</i>. Diagnostic of this shrubland association is the codominance of <i>Alnus incana ssp. tenuifolia</i> and <i>Salix drummondiana</i> on sites that are flooded for brief periods during the growing season.  Accession Code: urn:lsid:vegbank.org:commConcept:31560-{CCC2ED87-3F1A-4ED2-BEEF-EF800D4418F1} Plot-observations of this Community Concept: 18
