I think its a birch tree and bark has been peeled of about a metre up tree, could it be a mammel or bird doing this or is it natural?
No interactions present.
Looks like larch to me, most likely culprit is a deer though I have seen squirrels strip bark like this.
Roe and other kinds of deer do use their antlers to rub off bark and fray the wood underneath during the autumn rut and while marking territories in spring, and I don't think they care if the tree is alive or dead, so deer damage / fraying would be my guess.
