Trapping, as I said.... They can only harvest excess animals in a herd, so by default if they have a successful trapping season, you'd have to assume that the herd is healthy and has reached its carrying capacity. They do not allow an overpopulation, which actually will cause sickness among the animals. They also turn in the carcasses to the biologists in our province, every number, every pelt, to make sure that in fact these animals are healthy, so they play a very important part. It's not as if they are hare-hunting, where we don't know how many hares are harvested. When the fur-bearers are harvested, we know exactly how many animals, so it would be very indicative of the population and the health of these herds.
