Huh, I remember learning at some point that removing bark around the entire perimeter of a tree interrupts water flow and eventually kills the tree. Is that only some trees then? Or was I totally misinformed?
Cork oak is unique in its ability to regenerate its outer bark. After a tree reaches 25 years of age, it can be stripped of its cork once every 9 to 12 years without causing damage to the tree. A single cork oak, which lives up to 200 years, can be harvested over 16 times.
Cool thing I learned: harvested cork oak stores 5x as much carbon as unharvested. Get that cork!
Depends on the tree species, technically the only living part of a tree trunk is a thin layer of material right under the visible bark. If you go around and expose the wood in a circle around the trunk the tree will die, but I guess if you’re careful the bark can be harvested without harming the tree.

Same! Digging into this wiki says (with source):
