Brown bear-livestock conflicts in a bear conservation zone in Norway: are cattle a good alternative to sheep? Barbara Zimmermann1, Petter Wabakken, and Michael Dotterer Facultyof Forestryand WildlifeManagement, Hedmark University College, N-2480 Koppang,Norway Abstract: We evaluated the potential for reducing livestock conflicts within a bear (Ursus arctos) conservationzone by replacingsheep with cattle. We interviewedcattle farmersand veterinariansand investigatedlivestock and depredationstatistics from governmentalland-use and wildlife management in HedmarkCounty, south-easternNorway. This county bordersa reproducingbrown bearpopulation in Sweden and alreadycontains several residentmale brown bears. A brown bear conservationzone, within which beardensity is plannedto increase,covers 46% of the county's surface.There were about 7 times as many free-rangingsheep (128,600) as cattle (18,200) during summer 1998, with densities lowest inside the bear conservationzone. Estimatedfree-ranging cattle mortalitywas about 16 times lower than sheep mortalityin summer 1998. During the past 13 years, no cattle were confirmedas killed by brown bears. The perceptionof the brown bear as a threatto cattle is higher among farmers than among veterinariansor managers.We found little supportfor the allegation that cattle become more difficultto control in the presenceof brown bears. Regardingbrown bear predation,we consider cattle a good alternativeto sheep in Norway. In southeasternNorway, however, the expected ex- pansion of the brown bear reproductionarea and an increasingwolf (Canis lupus) populationmakes this assertion less certain. We stress the need for researchon the predatorybehavior of large male brown bears and wolves, as well as on measures to protect free-rangingcattle against potential predation.
