Reference:
NatureServe Biotics 2019
Description:
This macrogroup consists of low to tall shrublands, meadows, and mosaics of the two in the Pacific Northwest region. Shrublands dominate and characteristic species include <i>Alnus viridis, Rubus spectabilis, Salix alaxensis, Salix barclayi, Salix glauca, Sambucus racemosa, Spiraea stevenii</i>, and <i>Vaccinium ovalifolium</i>. Meadows and grassland vegetation also occur and may be dominated by forbs, graminoids, or ferns. Dominant species include <i>Athyrium filix-femina, Calamagrostis canadensis, Chamerion angustifolium, Heracleum maximum, Veratrum viride</i>, and <i>Valeriana sitchensis</i>. Shrublands occur on flat to steep slopes at low to mid elevations (1-1000 m) in valleys, hills and mountains of the Aleutians; in southeastern Alaska and British Columbia they occur on mountain sideslopes from sea level to treeline where slopes are steep enough to produce frequent snowslides preventing forest development. Herbaceous stands include a wide variety meadows and grasslands that 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, ravine sideslopes and avalanche tracks. The macrogroup includes areas that are a mosaic of meadows with alder patches.
