Rub Tree Photo and Description
Both black bears and grizzly bears will scent mark by biting, clawing, and rubbing their bodies on trees
and fence posts. These marking posts appear very similar for both species and maybe impossible to
distinguish to species without accessory clues (hair left on the tree, tracks associated with the marking
post). Grizzly bears and black bears have also been documented to use the same marking posts in places
where the two species co-exist.
Photo 4. Two lodgepole pines that have been repeatedly
marked by grizzly bears. Look for bark removed at
about standing head height for a bear, claw marks and
bite marks as well as smooth bark about rump and
shoulder height for a bear. Northwestern Montana.
