What’s All the Bark About?

Tags: bark tree

Why do trees have bark?

Bark is essentially the skin of a Tree. It protects the inner layers of the tree, just like our skin protects our body from insects, disease and damage. It’s quite handy. Of course, the tree will survive if some of its Bark is stripped away, just like we will survive if we scrape our elbow. However, if too much of the bark is damaged, the tree will die.

Why are there different kinds of bark?

As trees grow, they get taller and wider, and when this happens, the bark has to grow with them. Each type of bark responds differently to these growing pains.

Sometimes the outer layers of bark (the periderm) grow smoothly with the tree, stretching to for a single smooth layer of skin.

And other times, the periderm doesn’t grow quite as fast as the tree, which results in a rough, uneven layer of skin that breaks apart creating valleys and ridges.

Sometimes when the bark cannot grow as fast as the tree, the bark will form layers that seem to peel back and flake off.
