The biodiversity in these forests is low compared to the other forests on the planet, having much less plant diversity and much less animal diversity, thus they are very monotonous.

Most of the boreal forests stretch on the territories of the two biggest countries in the world, Russia and Canada, with parts of it being in Scandinavia and Alaska as well.
