  1. Translocate to re-establish or boost populations in native range

    A study in 1990–1993 in forests in Montana, USA (Servheen et al. 1995) found that three translocated female grizzly bears Ursus arctos horribilis successfully established ranges around the release site and that two survived for at least three years. All three translocated bears established movement and habitat-use patterns similar to those of non-translocated bears (no data reported). Two of the three bears survived for at least three years. Three adult female bears were translocated from the border area of Canada and the USA to the Cabinet Mountains in Montana, USA. Bears were monitored by radio-tracking until their collars failed or to the end of the study period after three years.
