Chances of tree surviving bark damage

[Ben93]

I got a new mini cherry tree and it has a ring about a centimeter thick of back missing amount the tree amount where the graft is. Will the bark grow back as i can see the green layer at the moment.

Providing the cambium layer is undamaged Ben, new bark will grow.
Is the ring right round the tree?

[Ben93]

It goes round just below the graft its only tiny so i think it should heal, the trunk isnt even an inch thick yet. Its just a green ring amound the tree

Sounds ok Ben. Just keep an eye.
