CNVC00338 is a boreal coniferous woodland Association that occurs on the island of Newfoundland. The tree layer is open and dominated by scrubby black spruce (Picea mariana). The shrub layer is dense with abundant black spruce layers of varying ages and ericaceous shrub species, mainly rhodora, (Rhododendron canadense), early lowbush blueberry (Vaccinium angustifolium) and, to a lesser extent, sheep laurel (Kalmia angustifolia). Pale bog laurel (K. polifolia), common Labrador tea (R. groenlandicum), Bartram’s serviceberry (Amelanchier bartramiana) and Canada yew (Taxus canadensis) are less abundant, but common species. The herb layer is well developed to dense, and commonly includes trailing arbutus (Epigaea repens), creeping snowberry (Gaultheria hispidula), wavy hairgrass (Avenella flexuosa), twinflower (Linnaea borealis), sheathed sedge (Carex vaginata), bunchberry (Cornus canadensis), goldthread (Coptis trifolia), wild lily-of-the-valley (Maianthemum canadense) and black crowberry (Empetrum nigrum). Red-stemmed feathermoss (Pleurozium schreberi) dominates the continuous moss layer. CNVC00338 occurs in western Newfoundland where the climate is very humid, maritime influenced boreal. It occurs in areas where there is limestone bedrock overlain by a shallow ericaceous mor; the vegetation represents a mixture of species of both nutrient poor and rich requirements, but overall sites are moist to wet and nutrient poor. CNVC00338 is a stable condition that would readily regenerate after fire and logging, primarily by vegetative layering of black spruce.
