  1. Release translocated/captive-bred mammals in areas with invasive/problematic species eradication/control

    A before-and-after study in 2006–2008 in a temperate forest area in Tennessee and North Carolina, USA (Yarkovich et al. 2011) found following the onset of translocations of black bears Ursus americanus away from an elk Cervus canadensis calving site, survival of the offspring of translocated elk increased. A higher proportion of elk calves survived their first year during bear translocations (69%) than before (59%). In 2001–2002, fifty-two elk were translocated to the Great Smoky Mountains National Park. Calf survival was monitored in 2001–2006 in a previous study that indicated that black bears predated nine out of 13 elk calves killed by predators. In 2006–2008, forty-nine black bears were relocated >40 km away from the elk calving area. In 2006–2008, forty-nine elk births were documented from which 42 recently-born calves were radio-collared. Calf survival was monitored by radio-tracking and visual observation.
