We are currently completing a multiyear project investigating demography and habitat use of a harvested population of wolverine (Gulo gulo) in a 7,000-km2 area within the Kootenay region of British Columbia. The study area contains 10 registered traplines, 2 national parks, a major transportation corridor, 2 hydroelectric reservoirs, and active logging areas, and supports a substantial helicopter skiing industry. Wolverine are considered vulnerable by the British Columbia Wildlife Branch; consequently, vital rate data are important for evaluating management/conservation options. A total of 39 (14F, 25M) adult and subadult wolverine have been captured over 3,700 trap-nights using log-box traps baited with available road-killed wildlife. Population estimates for the core 4,000-km2 study area based on 4 years of live-trapping data are 25.6 (95% CI: 15.6–55.3) and 24.0 (95% CI: 14.7–44.3) for 1996 and 1997 respectively. Six of 11 mortalities detected during the study to date have been human caused...
