They never cease to stir up controversy and debate. And some Montana wolves will be studied more closely.  A Montana Fish, Wildlife and Parks biologist will use a helicopter in the Boulder River drainage south of Big Timber to put radio collars on wolves in two packs. That should start happening in the coming week. The study involves locating wolf packs, tranquilizing at least one animal in each pack, fitting them with collars and releasing them in the same location. Biologists will then use radio receivers to track the packs' movements. It should also help with population counts and follow up if livestock depredation occurs. I'm not sure if it will tell them anything they don't already know, but population counts are a key in determining harvest quotas. The current season's harvest count as of today was 154.  DB
