Return rate of the relocated wolves must be low. If these wolves returned, pack size and pup production might not be adequately reduced. Compensatory predation by single wolves not associated with packs or by the alpha pair must not become excessive. The kill rate by grizzly bears must remain comparable to current levels. Mortality rates of relocated wolves must be comparable or lower than mortality rates for naturally dispersing wolves.
Individual wolves kill many calves.
It has been documented that during 1994 an 1995 individual wolves killed between 25 and 40 Fortymile calves during the first 15 days of calving. By reducing the number of wolves, the actual number of calves killed by wolves may decline. Wolf pups increase the pack s food requirements. Subordinate wolves commonly disperse. Average distances moved by dispersing wolves in Alaska are 50-70 miles.
