Wolf-moose research in summer 1982 at ISRO centered on measuring the reproductive performance of both the moose population (in the early stages of an apparent recovery) and the wolf population (at its lowest level since colonization of the island over 30 years ago). At year's end at least 35% of the moose population was comprised of animals born in 1981 or 1982. All four potentially breeding females in the wolf population bore young, and a minimum of 10 pups were alive midsummer. Also discussed is the distribution of wolf summer home sites and habits; and moose yearling survival, adult moose sex ratio, a summer index to moose density and characteristics of moose mortality.
