Exotic tree species in the forest mean loss of grazing land for reindeer

Semi-domesticated reindeer avoid winter habitats with exotic lodgepole pine (Pinus contorta), introduced from Northern America. Reduced food supply and dense stands probably contribute to the reindeers' avoidance behavior of areas with tall P. contorta-trees. This is reported by researchers from Umeå University and the Swedish University of Agriculture, SLU in the journal Forest Ecology and Management.
