During 1984 study efforts at Isle Royale concentrated on wolf-moose and moose-vegetation interactions. During the 1984 summer field season, reproduction was confirmed in two of the three existing wolf packs. Moose calf production and recruitment declined slightly from 1982 and 1983 levels, so only slight increase in moose population is possible in 1985. Fourteen moose were immobilized and outfitted with radio-transmitter collars to study moose foraging behavior which will be completed during the next two years. Recruitment of moose calves now exceeds adult mortality by about 5%; at that rate the moose population will double by the late 1990s.
