The dominant trees of the taiga are black spruce (Picea mariana) and tamarack (Larix laricina), mixed with smaller numbers of white spruce (Picea glauca), dwarf birches, willows, laurels, and rhododendrons. The boglands are a habitat of sedges and sphagnum moss. Fauna
The characteristic trees are black spruce (Picea mariana), white spruce (Picea glauca), jack pine (Pinus banksiana) and tamarack (Larix laricina) . Ground cover includes extensive dwarf birch (Betula nana), ericaceous shrubs , cottongrass , lichen and moss.
Picea koyamae – Koyama's spruce, Japan (mountains) Picea mariana – black spruce, northern North America; Picea meyeri – Meyer's spruce, northern China (from Inner Mongolia to Gansu) Picea obovata – Siberian spruce, north Scandinavia, Siberia; often treated as a variant of P. abies (and hybridises with it), but has distinct cones
The major plant communities in this ecoregion, which are characteristic of the taiga biome, primarily consist of black spruce (Picea mariana) and tamarack (Larix laricina) forests. Species which commonly dominate the forest undergrowth are birch , willow , and marsh Labrador tea (Rhododendron tomentosum).
Characteristic trees are black spruce (Picea mariana), with shrubs of dwarf birch (Betula nana), Labrador tea (Ledum decumbens), and willow . Higher elevations support mixed forests of white and black spruce ( Picea glauca ), jack pine ( Pinus banksiana ), lodgepole pine ( Pinus contorta ), tamarack ( Larix laricina ), quaking aspen ( Populus ...
Black spruce (Picea mariana) and white spruce (Picea glauca) are the two most common trees, with lodgepole pine (Pinus contorta subsp. latifolia) being found in very dry or burnt sites. South-facing, low elevation slopes are often characterised by grassland communities.
Black spruce (Picea mariana) and tamarack (Larix laricina) are the predominant tree species. Where the soil is not saturated year round grows northern white cedar (Thuja occidentalis). Speckled alder (Alnus incana) grows around the edges of these swamps and red spruce (Picea rubens) and white pine (Pinus strobus) grow on higher, drier ground.
