Taiga or boreal forest is one of the most pristine biomes on earth. This biome spins the Northern Hemisphere in a wide swath across Alaska, Canada, Russia and Scandinavia, forming the world’s largest continuous biome. Most of taiga's trees are conifers, or trees that make cones: cedars, cypresses, firs, hemlocks, junipers, larches, pines, redwoods, sequoias, and yews.

The spruces are very common in taiga, and you can find the Norway spruce in European forests and the Siberian spruce in Siberian taiga. In North America, one can find the white spruce and black or bog spruce in boreal forest.
Conifer needles and bark of the trees contain a sap called resin. If you make a small cut in a pine tree, you will see resin oozing out. It is very sticky and it does not taste good.
