CNVC00122 is a boreal coniferous forest Association that occurs in Alberta. It has a moderately closed canopy dominated by lodgepole pine (Pinus contorta) and a relatively species rich understory. The shrub layer varies from moderately to well developed and typically includes squashberry (Viburnum edule) and prickly rose (Rosa acicularis), although green alder (Alnus viridis) can be abundant when present. The well-developed herb and dwarf shrub layer typically includes twinflower (Linnaea borealis), bunchberry (Cornus canadensis), fireweed (Chamerion angustifolium), dwarf raspberry (Rubus pubescens) and downy lymegrass (Leymus innovatus). The moss layer is well developed and dominated by stairstep moss (Hylocomium splendens), knight’s plume moss (Ptilium crista-castrensis) and red-stemmed feathermoss (Pleurozium schreberi). CNVC00122 occurs on mesic to moist, nutrient-medium sites in a region with a subhumid continental climate. It typically establishes as the first cohort after fire. Two subassociations are distinguished, typic and Alnus viridis.
