Abstract I examined the sex and age at death of Asiatic black bears (Ursus thibetanus) killed by sport hunters or during nuisance incidents in 2 neighboring mountain ranges (Kitakami Highland [KH] and Ohwu Mountains [OH]) in northern Honshu, Japan. Between 1993 and 2000, 1,005 bears were killed in these areas (361 nuisance kills, 644 sport-hunting kills). Nuisance bear removals were 1.3 times greater in KH than in OM.

The monthly nuisance removals varied widely by year in both areas, with the largest yearly variation in September in KH and August–September in OM. Female deaths accounted for much of the increase in nuisance kills in KH during September. Both sexes contributed to the increase in OM nuisance kills during August and September. The number of bears killed by sport hunting in KH was 4.7 times larger than in OM. OM terrain is steep and...
