CNVC00323 is a boreal coniferous forest Association that ranges from Alberta to Manitoba. It has a moderately closed canopy of jack pine (Pinus banksiana) and/or black spruce (Picea mariana), usually with jack pine dominant. The shrub layer is usually moderately developed and typically includes the heath species common Labrador tea (Rhododendron groenlandicum) and velvet-leaved blueberry (Vaccinium myrtilloides), as well as regenerating black spruce. Lingonberry (V. vitis-idaea), bunchberry (Cornus canadensis) and twinflower (Linnaea borealis) are common in the moderately developed herb and dwarf shrub layer. A well-developed moss layer dominated by red-stemmed feathermoss (Pleurozium schreberi), with lower abundance of stairstep moss (Hylocomium splendens), further characterizes this Association. Patches of green reindeer lichen (Cladina mitis) are usually present. CNVC00323 occurs on mesic, nutrient-poor to medium sites in a region with a subhumid continental boreal climate. It typically establishes as the first cohort after fire.
