Name: Picea engelmannii / Caltha leptosepala Swamp Forest Reference: NatureServe Biotics 2019 Description: This forest association is found east of the Continental Divide in Wyoming on cold and subirrigated sites along streambanks and terraces between 2499 and 2896 m (8200-9500 feet) elevation. It also occurs in north-central Wyoming in the Big Horn Mountains and in the southern and western portions of the Uinta Mountains of Utah between 3048 and 3322 m (10,000-10,900 feet) elevation. Soils are noncalcareous and derived primarily from granitic alluvium. <i>Picea engelmannii</i> dominates both late-successional and early-seral communities; <i>Abies lasiocarpa</i> is occasionally present but is stunted and unhealthy. Minor seral components are <i>Pinus contorta</i> and <i>Pinus albicaulis</i>. The shrub layer is not diverse, but common shrubs present include <i>Vaccinium cespitosum</i> and <i>Vaccinium scoparium</i>. The herbaceous undergrowth is floristically rich, with either <i>Caltha leptosepala</i> or <i>Trollius laxus</i> having at least 5% cover. A number of other wet-site forbs and graminoids are present to abundant, including <i>Arnica</i> spp., <i>Calamagrostis canadensis, Deschampsia cespitosa, Mitella pentandra, Parnassia fimbriata, Saxifraga odontoloma, Senecio triangularis</i>, and species of <i>Carex</i> or <i>Juncus</i>. On drier sites, <i>Antennaria microphylla, Danthonia intermedia, Poa nervosa</i>, and <i>Trisetum spicatum</i> are present.  Accession Code: urn:lsid:vegbank.org:commConcept:29266-{C00B35FA-68DC-4A79-BEFE-3CC63EEE2135} Plot-observations of this Community Concept: 0
