- WOLF PREDATION ON MOOSE - A CASE STUDY USING HUNTER OBSERVATIONS. Warn, Hilde Karine; Hjeljord, Oiav // Alces;2003, Vol. 39, p263
We studied predation by colonizing wolves on a high density and highly productive moose (Alces alces) population in south-eastern Norway (about 1 .5 moose and 0.01 wolves per km� in winter). As indices to population changes, we used hunter observations. Over the summer, the wolf pack utilized...
