Cornus sericea / Heracleum maximum Wet Shrubland | NatureServe Biotics 2019

Name: Cornus sericea / Heracleum maximum Wet Shrubland Reference: NatureServe Biotics 2019 Description: This association occurs at mid elevations, below 2135 m (7000 feet), most commonly from the Wasatch Range of Utah, north through eastern Idaho. This early- to mid-seral association usually forms on infrequently flooded terraces along moderate- to high-gradient streams of variable size. The development of Mollisols on these terraces indicates that this association is stable enough for the incorporation of organic matter into otherwise well-drained and rocky soils. Tall <i>Cornus sericea</i> forms a dense shrub layer with an average cover of about 70%. <i>Salix boothii, Salix lutea</i>, or other <i>Salix</i> spp. are sometimes subdominant, while <i>Rosa woodsii</i> and <i>Ribes</i> spp. are common with low cover. The herbaceous understory is variable, but <i>Heracleum maximum</i> is diagnostic, usually with at least 5% cover (typically 15-20%); its cover is usually greater than any other herbaceous species. Other frequently occurring species, all with low to moderate cover, include <i>Galium triflorum, Geum macrophyllum, Maianthemum stellatum, Mertensia ciliata</i>, and <i>Urtica dioica</i>. It is distinguished from similar associations by the presence of a generous herbaceous layer dominated by <i>Heracleum maximum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:30076-{1806711F-CA8F-4129-9D30-66FCB8B8CDC8} Plot-observations of this Community Concept: 0
