Today I noticed that our apple tree has a limb that has been stripped almost completely bare of its bark. It was too late in the day to get a photograph of it, but it was quite a nude branch.
Google search results indicate that it is probably squirrels. The other possibilities would involve damage lower on the tree trunk. The bark had been stripped off of a horizontal limb. The only bark still on the limb was around a knot on the underside of the limb, which told me that the offender was on top of the limb.
Has anyone else has any such marauding squirrels?
