Name: Cornus sericea / Heracleum maximum Shrubland
Reference: Western Ecology Working Group of...
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 Cornus sericea forms a dense shrub layer with an average cover of about 70%. Salix boothii, Salix lutea, or other Salix spp. are sometimes subdominant, while Rosa woodsii and Ribes spp. are common with low cover. The herbaceous understory is variable, but Heracleum maximum 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 Galium triflorum, Geum macrophyllum, Maianthemum stellatum, Mertensia ciliata, and Urtica dioica. It is distinguished from similar associations by the presence of a generous herbaceous layer dominated by Heracleum maximum (= Heracleum lanatum).
