As the warmer air at lower latitudes rises, the cold polar air rushes down to take its place. In the extreme cold winter temperatures, these blizzards carry ice crystals that destroy any vegetation that isn't low enough to hide under the snow during the winter months.
Just below the surface, the ground in this cold area remains frozen all year long, and the permafrost keeps trees from growing roots long enough to hold them upright.
