Another important part of our research is to collect information on bears that have been killed during hunting. We obtain information on weight, a tooth for age determination, skin, hair, and tissue samples, the reproductive organs, killing site and killing date, method of hunting and information about whether the bear was marked and/or tattooed inside the lip. This gives us data from bears both inside and outside our study areas, from bears the we have only ID-marked, and from bears we have lost contact with. Extensive genetic studies have been made based on hair and tissues from both killed and marked bears. The information the hunters provide about the hunt is valuable data for studies of the effects hunting has on the bear population.
