Bears rub on many objects, each with it's own challenges for marking and attaching barbed wire or other hair collecting device. Below are diagrams of how we set up bear rub trees, bear rub trees that were also pack bumps (trees bumped by horses/mules/etc carrying packs), and fences bears pass through regularly. Read section titled Rub Object Surveys on the Northern Divide Grizzly Bear Project details page for more information.
