Research is mainly done by following bears with radio transmitter. Bears are immobilised in spring by using a helicopter, radio marked with a collar. They are weighed and measured.  Some samples are taken, including a tooth for age determination of older bears. Depending on the actual study the bears are localised twice to four times a month by car or airplane. In the beginning of the project the project was only focused on male bears, but today we are mainly working with marked female bears and we mark their yearlings while they are still together. Females with cubs are not captured. The collars for younger bears have a weakening zone breaks away in case we loose contact with the bear. Adult bears are immobilised in every 2-3 years, where they get new collars. Young bears, which are growing fast, receive transmitters which are implated in the body cavity. We do this to avoid capturing them every year as they grow. The operation is conducted by the project verterinarian Prof. Jon Arnemo who developed the method in Scandinavia. By locating the bears each week we can determine their use of area and document their dispersal. We can also locate a bear and can analyse the reason for its death.

Another important part of 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, killing site and killing date, method of hunting and information whether the bear was marked and/or tatooed inside the lips. This gives us data from bears that are outside our study areas. Extensive genetic studies have been made based on hair and tissues from both killed and marked bears.

A detailed description of the capture, immobilization and radiomarking procedures is available in the document "Biomedical Protocols for Free-ranging Brown Bears, Gray Wolves, Wolverines and Lynx, 2007".

The Project has conducted research on population dynamics, life history, behavioral ecology, sexually selected infanticide,  homeranges, body weight development, choice of biotop, predation on moose, choice of food in general, genetics, hibernation, choice of denning site, danger for humans, sensitivity for human interruptions, and in  Norway even predation on sheep. We conclude that the Scandinavian brown bear, even though he is the same species than the North American brown bear, differs from it in many ways. Scandinavian bears are more productive, disperse more, eat more ants but less fish, rodents and roots, is much less agressive and preys less on adult moose.  The ecology and demography of the Scandinavian brown bear is more simular to that of Central and Southern European bears than with the North American bears.
