North American coniferous forest

A North American coniferous forest is characterized by needle-leaved or scale-leaved evergreen trees that bear cones. These forests are found in regions with long winters and substantial precipitation. Dominant trees include pines, spruces, firs, and larches, often forming dense stands with an understory of shrubs or herbs. The forest floor is typically covered in mosses, liverworts, and lichens.1

The soils, known as podzols, are acidic and have a compacted humus layer, making them low in mineral content and invertebrates. Common inhabitants include insects like mosquitoes and flies, various birds such as woodpeckers and owls, and mammals like squirrels, moose, and wolves. In North America, white spruce, black spruce, and balsam fir are prevalent, with lodgepole pine and alpine fir significant in the west. A distinct subtype is the moist temperate coniferous forest along the west coast, sometimes called temperate rainforest, featuring giant trees like Sitka spruce and Douglas fir.1
