paw width wide and the top edge of it is generally rectangular in shape. Photo by David Moskowitz.
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.
