The age structure of Moose (Alces alces) killed by gray Wolves (Canis lupus) is available from only two national parks in the united States where hunting by people is not allowed and from three areas in Alaska where Moose are hunted (Mech 1966; Peterson et al.1984; Ballard et al. 1987; Mech et al. 1998). The samples of Moose killed by gray Wolves from each hunted area are relatively small (47–117), given that Moose live to 20 or more years (Passmore et al. 1955). This article adds age data from another 77 Moose killed by gray Wolves from a fourth (lightly) human-hunted area and assesses the age structure of all the samples.
