G355 Calamagrostis canadensis - Chamerion angustifolium - Athyrium filix-femina Grassland & Meadow Group
Type Concept Sentence: This is an herbaceous meadow group that occurs on a variety of habitats with a mesic moisture regime, including balds, windswept exposed ridgetops, coastal headlands, and ravine sideslopes, where the vegetation may be dominated by forbs, graminoids, or ferns; the most common dominant species are Athyrium filix-femina, Calamagrostis canadensis, Chamerion angustifolium, Heracleum maximum, and/or Veratrum viride.
Common (Translated Scientific) Name: Bluejoint - Fireweed - Common Ladyfern Grassland & Meadow Group
Colloquial Name: Northern Vancouverian Grassland & Meadow
Hierarchy Level: Group
Type Concept: This is an herbaceous group that includes a wide variety of balds, meadows and grasslands. Vegetation may be dominated by forbs, graminoids, or ferns. The most common dominant species are Calamagrostis canadensis and Chamerion angustifolium. One or more of the following species can also be dominant: Veratrum viride, Athyrium filix-femina, or Heracleum maximum, or a combination of any of these. Other common forb species may include Achillea millefolium var. borealis, Aconitum delphiniifolium, Angelica lucida, Antennaria dioica, Arnica unalaschcensis, Cardamine oligosperma var. kamtschatica, Castilleja unalaschcensis, Claytonia sibirica, Chrysanthemum arcticum ssp. arcticum, Dryopteris expansa, Geum calthifolium, Lupinus nootkatensis, Nephrophyllidium crista-galli, Polemonium acutiflorum, Ranunculus occidentalis, Sanguisorba canadensis, Senecio triangularis, Solidago canadensis var. lepida, and Valeriana capitata. Graminoids include Agrostis exarata, Agrostis scabra, Carex macrochaeta, Deschampsia beringensis, and Festuca rubra. The low subshrub Empetrum nigrum may also be common. Stands occur on all slopes and aspects with a mesic moisture regime, including windswept coastal headlands, coastal bluffs, old beach ridges, hillside slopes, stabilized talus, alluvial fans, rolling hills, alluvial slopes, below subalpine shrublands, and ravine sideslopes. The group includes areas that form a mosaic of meadows with alder patches. Soils are typically mesic, well-drained, and underlain by colluvium, alluvium, glacial till or residuum.
Diagnostic Characteristics: Herbaceous cover is >25%; stands dominated by Veratrum viride, Athyrium filix-femina, or Heracleum maximum or a variety of other herbaceous species. Leymus mollis cover is <25%.
