The trees of this habitat include Eastern hemlock, white, red and black spruce, white and red pine, balsam fir and eastern larch. Most herbaceous plants are scattered in open areas such as ravines where tree concentrations are less and sunlight can penetrate. Flowering species include jack-in-the-pulpit, wild lily-of-the-valley, wild sarsaparilla, and clintonia. Non green plants such as Indian pipe as well as a wide variety of mushrooms will occur seasonally in the dense shade of a coniferous woodland.
Red squirrels, red-backed voles and mashed shrews, and a variety of bird species including spruce grouse, boreal warblers, gray jay, pine siskin, golden-crowned kinglet, crossbills, chickadees, and black-backed woodpecker call the coniferous woodland home. Spiders and many types of insects populate the canopy layer, while snails, slugs, beetles, and carpenter ants feed on decaying tree matter and fungi growing on rotting fallen trees.
