Name: Agastache urticifolia - Geranium viscosissimum - Pteridium aquilinum Montane Mesic Meadow Alliance Reference: NatureServe Biotics 2019 Description: The vegetation of this montane mesic meadow alliance is characterized by an often patchy, moderately dense to dense herbaceous layer dominated by perennial forbs. Diagnostic and dominant species are <i>Agastache urticifolia, Geranium viscosissimum, Heliomeris multiflora, Mertensia ciliata, Pteridium aquilinum</i>, and/or <i>Wyethia amplexicaulis</i>. Associated species are diverse and include widespread forbs such as <i>Achillea millefolium</i> or <i>Senecio triangularis</i>, and mesic graminoids such as <i>Bromus carinatus, Carex microptera</i>, and <i>Elymus trachycaulus</i>. Scattered clumps of the deciduous shrub <i>Symphoricarpos oreophilus</i> are common, and occasional <i>Populus tremuloides</i> trees may also be present. Plant associations occur in the central Rocky Mountains of Wyoming, Utah and Idaho extending west to ranges in Nevada. Sites vary from gentle to steep slopes with eastern to southwestern aspects, but are most often moderately steep mid to upper slopes. Stands also occur along small streams, benches near seeps, and on moist toeslopes in narrow valley bottoms. Elevations range from 1970-2835 m. Soils are moderately deep to deep, well-drained loams with a thick mollic horizon. The water table ranges to depths of 20 cm. Soils are developed from colluvium and more recently alluvium and are derived from limestone, sandstone or shale parent materials and have clay or clay loam textures.  Accession Code: urn:lsid:vegbank.org:commConcept:39160-{6B49D7F1-E1F4-4AE3-8FF6-07307BEB305C} Plot-observations of this Community Concept: 0
