I feel there are 2 different reasons....The first post was definitely antler Rub!!! The pic of moose eating bark was obvious!!! The antler rubs are gores in the tree, gouges, when they strip the bark to eat it, they dig their bottom front teeth (that's all they have) into bark, and strip it off to eat. It's obvious at the top of the wound that bark has been pulled off. I have watched them do both, very different marks.
I agree with Deerdr 100%. They are gouges in the tree, not strips of bark being tire off. Too uniform, if it were moose eating the bark, there would be tear marks where the moose would be stripping it off. They obvious gouges.
Mcmack, they are 100% moose tracks as there is nothing else in N.B. woods that makes a track that size.
