Just curious if anyone has ever seen sugar maples have "pimply" bark, and if you know what causes it. I've got a stand of them that all have it. I think i read somewhere once that it's not harmful. Sorry I don't have any pictures of it at this time. It covers every inch of them from the ground to about 8ft up. Little bumps about the size of an easer on the end of a pencil,or smaller.
Thanks
