Name: Picea engelmannii / Calamagrostis canadensis Forest
Reference: Western Ecology Working Group of...
Description: This forest plant association occurs on cool, moist sites at low to high elevations in the Rocky Mountains of Montana, Wyoming, and southeastern Idaho. It is generally restricted to flat to gently sloping sites with poor drainage, such as fen and lake margins, toeslopes, and low stream and river terraces. This community usually is saturated for a good portion of the year, and stands have a high water table year round. The ground surface in these stands is characterized by a large amount of microtopography stemming from wind-thrown trees. The overstory is dominated by Picea engelmannii or Picea engelmannii X glauca hybrids, and Abies lasiocarpa may also be present. Not infrequently Pinus contorta is a long-persisting seral component. Shrub canopy coverage is low, although the diversity of shrub species present is fairly high. Calamagrostis canadensis and Calamagrostis stricta are diagnostic species when well-represented; usually under these shaded forest conditions Calamagrostis canadensis dominates the ground layer, often forming what appears to be a pure grass sward.
