No, birch trees do not die when they lose their bark. While the bark of a birch tree is important for protection and nutrient transport, the tree can survive and continue to grow even if it loses its bark.
They could be hit by disease, an insect borer, or the roots could lose their water source.
no they don't
Trees have bark for protection. If the bark were to be torn off then, the tree would die faster and be prone to termites.
Bark beetles bore through the bark to eat the tasty nutrients in the inner bark known as the phloem and cambium layers. If they eat all the way around the tree, they will girdle the tree and the tree will die. Girdling cuts the trees food tubes and it will be unable to send nutrients up and down the trunk.
Trees die if a ring of bark is removed because it will stop water getting from the roots to the leaves.
