During its 27th year this study remained focused on wolf-moose interaction, with an additional goal of understanding the link between moose forage levels and population dynamics. The research involves three levels of this ecosystem: carnivore, herbivore, and vegetation. In 1985, the wolf population at Isle Royale changed little in total size from 1984. The wolf population has been stabilized by relatively high mortality of undetermined cause. The moose population is increasing steadily as recruitment remains relatively high and mortality low. Seventeen moose were radio-collared during the past year as part of a study of moose foraging behavior. The beaver population continued to increase during 1982-84 after reaching a low level during the peak in wolf numbers in 1980.
