Translocate predators away from livestock to reduce human-wildlife conflict Terrestrial Mammal Conservation

A study in 1989–1992 of forest and meadow in an area of Oregon, USA (Armistead et al. 1994) found that black bears Ursus americanus translocated away from areas with histories of bear attacks on sheep were not subsequently involved in livestock predation. None of five radio-collared, translocated bears was involved in sheep predation during the monitoring period (≤1 year). However, four of the bears died during that period (three were shot and one found dead) and one either moved away or its radio-collar malfunctioned. Sixteen bears were translocated in 1990 and five in 1991 from areas where five bears had been killed in 1989 to protect livestock. Bears were released ≤20 miles from capture sites. Bears translocated in 1991 were radio-collared. One was monitored for approximately one year. The others were monitored for shorter, unspecified, periods.
