We have all seen pictures and movies of grizzly bears rubbing against trees to scratch their backs. But, did you know that biologists can collect the hair that is left on the trees to collect DNA to study the bears in the area? Not only can population numbers be studied, but also territory size and attitudinal migration.
The grizzly bear and paw prints are on a 100% preshrunk cotton shirt. The artwork is by one of our favorite artists, Gregg Murray.
