The birch is usually mixed with larch and scorpion pine. There are also separate birch belts, the birch belt along the road is a landscape, a dense white and gray trunk flickering past, sometimes wind, the tree top leaves are winds rolled, revealing the reverse of the leaves silver white, like a half tree white flowers.
