MIGRATION DISTANCES OF MOOSE POPULATIONS IN RELATION TO RIVER DRAINAGE LENGTH
To aid moose management in Sweden we want to be able to predict the yearly distribution of migratory moose populations based on winter inventory data since summer inventory data are lacking. As a first step in developing this method, we compared migration distances of moose in 11 populations to the...
