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

    A controlled study in 1980–1990 in a large mountainous area dominated by coniferous forest in Oregon, USA (Stussy et al. 1994) found that translocated female elk Cervus canadensis had a lower survival rate than non-translocated female elk. The average annual survival rate of translocated female elk (77% of 35 individuals) was siginificantly lower than that of non-translocated female elk resident at the release sites (92% of 35 individuals) and also appeared lower than the average annual survival rate of female elk in the whole study area (89% of 184 individuals, this result was not compared statistically to other survival rates). The study area included six national forests and eight state wildlife management districts. In 1980–1990 one hundred and eighty-four resident female elk were released at their capture site. In 1987-1990, 35 female elk were caught, radio-collared and translocated. A further 35 resident female elk were radio-collared in 1988-1989 at the translocation release site. Distances between capture and release sites of translocated elk are not given. Both non-translocated and translocated elk were located 2–4 times/month, mostly from an aircraft.
