CNVC00120 is a boreal coniferous forest Association that occurs in Alberta, British Columbia and Yukon. It has a moderately closed canopy of lodgepole pine (Pinus contorta) and/or black spruce (Picea mariana), usually dominated by lodgepole pine. The understory is generally species poor. The poorly to well-developed shrub layer usually includes common Labrador tea (Rhododendron groenlandicum) and prickly rose (Rosa acicularis). The herb and dwarf shrub layer is moderately developed and includes lingonberry (Vaccinium vitis-idaea), bunchberry (Cornus canadensis) and twinflower (Linnaea borealis). A well-developed to continuous moss layer of stairstep moss (Hylocomium splendens), red-stemmed feathermoss (Pleurozium schreberi) and knight’s plume moss (Ptilium crista-castrensis) further characterizes this Association. CNVC00120 occurs on mesic to moist, nutrient-poor to medium sites in a region with a subhumid continental climate. It is often the first cohort after fire, but can succeed earlier seral conditions. Three subassociations are distinguished: typic, Rhododendron groenlandicum and Alnus viridis.
