CNVC00097 is a boreal coniferous forest Association that occurs in Alberta, British Columbia and Yukon. It has an open to moderately closed canopy that is dominated by white spruce (Picea glauca) and a relatively species rich understory. Prickly rose (Rosa acicularis) and squashberry (Viburnum edule) are common species in the moderately to well-developed shrub layer. Green alder (Alnus viridis) and/or mountain alder (A. incana) can be abundant when present. The herb and dwarf shrub layer is well developed and typically includes naked mitrewort (Mitella nuda), bunchberry (Cornus canadensis), tall bluebells (Mertensia paniculata), dwarf raspberry (Rubus pubescens), twinflower (Linnaea borealis), arctic sweet coltsfoot (Petasites frigidus) and fireweed (Chamerion angustifolium). The moderately to well-developed moss layer is dominated by stairstep moss (Hylocomium splendens), with lower cover of knight’s plume moss (Ptilium crista-castrensis) and red-stemmed feathermoss (Pleurozium schreberi). CNVC00097 is a late successional condition that occurs in a region with a subhumid continental climate. It is primarily found on moist nutrient-rich sites; these are among the most productive sites in the region. Two subassociations are distinguished, typic and Alnus spp.
