During 2008–2009, the wolf population increased slightly, from 23 to 24, and the moose population remained approximately stable at a relatively low level. East Pack experienced a dramatic decline during the past year, when four of its five adult wolves died and no pups survived. In 2009, we estimated the moose abundance to be 530. For the past three years, wolf abundance has been near its long-term average, and moose abundance has been about half its long-term average. These conditions are similar to those observed 50 years ago, when this project first began.
