Some characteristics of polar bears killed during conflicts with humans in the Northwest Territories, 1976-86

Abstract

Examined 265 cases where Ursus maritimus were killed in the Northwest Territories as a result of bear-human encounters. Subadult animals constituted 53% of the aged sample, and males accounted for 70% of the sexed bears. Subadult males represented 40% of known age and sex bears. Problem kills occurred throughout the year but were most frequent in the ice-free season (August-November). In 222 cases where circumstances surrounding the death were known, 63% were associated with Inuit on the land, 18% with settlements, 15% with industrial sites and 4% with research activities. This mortality in excess of the quota may adversely affect some populations. Wherever possible problem bears should be included on community quotas. -from Authors
