put my lovell rootstock in my fig chamber for the winter and when i checked it yesterday i noticed a bunch of rodent damage. theres some on my figs but im less concerned about those. i cant tell if these are passed the cambium or not. think the worst of these will be worth trying to graft this spring?
my persimmons and pawpaw seedlings went unscathed 
If they got the bark all the way around then the tops are dead. What you can do is dig a bit around it and graft where there is still bark at the soil line. I’ve done that numerous times, use a cleft or bark graft since it’s a flat top you will be grafting to.
is it possible to tell if they will make it by them pushing out growth when they wake up? do you think i should just do what you said regardless of the extent of the damage, on the ones that are, so that i remove the risk of them not recovering?
If there is no bark all the way around the circumference there is a 100% chance the tops will die. If there is a bit of bark left they will live. So on all the ones with the bark gone all the way around I would chop off the tops down to where there is bark again.
I just noticed about 100% loss of all of my apple and pear trees. All girdled below the top of the snowpack.
damn, sorry. my peaches in containers outside my chamber didnt have any damage. also, no snow so not sure about that.
i got a rodent in the trap today. will check again tomorrow.
yes, you have nothing to lose by trying to graft them! In spring, cut those down past the damage then graft like scott said!
having a stretch of decent weather i figured id tackle these girdled peaches:
a couple of them were girdled all the way around and i had to go below soil level. i dont normally use zipties but figured they would help hold better here than my typical rubbers.
with the bark slipping nicely and the stock being a double or larger than my scion i sort of with i would have done all bark grafts. used a mix of cleft/modified cleft and the last one was a bark graft.
