Spruce, pine, and fir are trees associated with the Coniferous forest. Coniferous forests are also called taiga or boreal forests, and they are characterized by coniferous trees that have needle-shaped leaves, which are well-suited to withstand cold and snowy weather. The coniferous forest is located in the northern hemisphere, in regions with long and cold winters and short summers. It covers vast areas of Canada, Russia, Scandinavia, and Alaska. The trees in this forest are important sources of timber and pulpwood.
