Name: Heracleum maximum Wet Meadow
Reference: NatureServe Biotics 2019
Description: This is a lush forb meadow type of the Northern Rockies, in northwestern Montana and southern Alberta. Stands of this herbaceous vegetation are found on moderately sloped to flat benches, valley floors, and colluvial slopes, predominately on glacial deposits, with southeast aspects between 1671 to 1700 m (5480-5574 feet) elevation. Soils are moderately drained to well-drained silt or clay loams, and the ground surface is mostly litter and duff. This lush herbaceous association consists of a wide diversity of graminoids and forbs. Occasionally a few scattered shrubs are present with up to 10% combined cover, including <i>Spiraea betulifolia, Amelanchier alnifolia, Dasiphora fruticosa ssp. floribunda</i>, and <i>Symphoricarpos occidentalis</i>. There is a wide variety of tall forbs including <i>Heracleum maximum</i>, which, while not present nor dominant in all stands, is the indicator species for this wet association. Forbs consistently present are <i>Osmorhiza occidentalis, Thalictrum occidentale, Potentilla gracilis, Fragaria virginiana, Achillea millefolium</i>, and <i>Valeriana sitchensis</i> with 2-20% cover. Graminoids present consist of <i>Bromus carinatus, Carex hoodii</i>, and <i>Carex geyeri</i>.
