CNVC00110 is a boreal coniferous forest Association that occurs in Alberta, Yukon and likely British Columbia. It has a moderately closed canopy comprising roughly equal proportions of black spruce (Picea mariana) and white spruce (P. glauca). Prickly rose (Rosa acicularis) and common Labrador tea (Rhododendron groenlandicum) typically occur in the moderately developed shrub layer. The herb and dwarf shrub layer is usually moderately developed and often consists of low abundance of many species, such as twinflower (Linnaea borealis), bunchberry (Cornus canadensis), tall bluebells (Mertensia paniculata), lingonberry (Vaccinium vitis-idaea), arctic sweet coltsfoot (Petasites frigidus), naked mitrewort (Mitella nuda) and dwarf scouring-rush (Equisetum scirpoides). The moss layer is continuous, consisting mainly of stairstep moss (Hylocomium splendens). CNVC00110 occurs in a region with a subhumid continental climate, primarily on moist, nutrient-medium sites. Stands typically establish following fire or harvesting, and are self-replacing over time.
