bridge grafting to possibly save a large willow tree recently partially girdled by beavers #923656

Can you refer me to someone who has experience with bridge grafting? I am wondering if this might be a life-saving option for a large willow tree which was recently partially girdled by beavers.
Attached are some photos of the damages. There is another, more extensively, recently damaged willow nearby that will probably die or at least start to obviously decline this spring. That tree could possibly be used as a source for grafts if that would be helpful. I can provide additional photos if that would be helpful.
Thank you very much.

Thanks for your question. Because only the bark is chewed it looks more like rabbit or vole damage to me. Nevertheless, there is significant damage. Bridge grafting is difficult. I doubt that grafting while the tree is dormant will be successful. To my knowledge, Extension does not maintain a list of experts on this topic that I could refer you to.
I believe the tree will survive because it is not totally girdled. I suggest that you place a robust barrier (metal fencing) to protect the tree from any further damage. No doubt the tree will grow new shoots near the base if the canopy dies back. I'm sorry to se such damage.
