 Bear walks through the barbed wire, leaves hair on a barb. We collect that hair weekly, burn off any excess, mark whether it was on the top or the bottom of the top strand, bottom strand, if it was on the first barb or the 57th barb. And each barb is a different sample, even though it may have been the same bear that left it. And then that bear, that hair from that bear or bears is sent to a laboratory in Canada
