Sammendrag
Hunting has traditionally been the main mortality factor of moose
Alces alces populations in Norway. The last decade however, the
Scandinavian wolf Canis lupus population has increased and the impact
of wolf predation has locally become an important mortality factor
that has to be considered in moose population management. Here we try
to separate the impact of different mortality factors on a local moose
population in Stor-Elvdal municipality, SE Norway, that is affected by
hunting, vehicle collisions and predation. We have used 1) survival
data from individually marked moose, 2) density estimates based on
hunter observations, 3) data from road- and railway killed moose, and
4) kill-data from ground-tracking unmarked wolves on snow. We have
estimated population performance by applying an age- and sex
structured model to estimate the relative impact of different
mortality factors. In addition, we simulated how moose density may
affect hunting potential in areas where wolves are present.
