Around the world, large carnivores are involved in human wildlife conflict by killing
livestock or compromising peoples’ safety. This results in widespread lethal persecution
that contributes to carnivore population declines. Alternatively, translocation of so-called
‘problem animals’ is an often-used approach to resolve conflict non-lethally. However,
translocations are rarely assessed in terms of their capacity to reduce conflict or their
biological and financial implications. This study evaluates the efficacy of this strategy by
investigating 22 intensively monitored translocations that were carried out into free-range
environments in Namibia between 2008 and 2012. Translocations involved 23 cheetahs
(Acinonyx jubatus) (plus 10 dependent offspring), six leopards (Panthera pardus) and one
brown hyaena (Parahyaena brunnea). Translocation objectives included conflict
mitigation and the rehabilitation of confiscated, indiscriminately trapped or orphaned
individuals. Study animals were released at an average distance of 404.3 km (47 – 816 km)
following captive periods ranging from 1 – 1,184 days. Using survival, livestock predation
and homing as key measures of translocation success one year post-release, out of 27
individuals with known outcomes, 44.4% were successful. Success was higher for leopards
(67%) than for cheetahs (40%), which were particularly unsuccessful if they habituated to
human presence during prolonged captivity. Human-induced mortality accounted for most
deaths in year one (58%; 10 cheetahs, one leopard, and the hyaena). Translocation success
did not differ significantly by sex (M: 39%; F: 50%) or between hard (47%) and soft
releases (40%). Regardless of species, release mode and recipient area size, all carnivores
displayed extensive post-release movements ranging beyond protected area boundaries, but
only two cheetahs returned to their capture site. Most animals that survived the first year
successfully reproduced (five leopard cubs, 14 cheetah cubs) and settled into permanent
ranges. Following an initial period of orientation and exploration, the ecology of
translocated large carnivores reflects that of resident conspecifics. Only three case studies
resulted in post-release conflict, but translocations did not resolve conflict on source
properties permanently, leading to repeat requests for carnivore removals by those land
managers. A farmland survey (26,090 km2, n = 221 respondents) demonstrated that
conflict with, and persecution of, large carnivores remain widespread, suggesting a high
potential demand for carnivore translocations. However, release area suitability modelling
across Namibia’s protected area network showed that only a few public or private reserves
can potentially accommodate individual cheetahs and leopards. Translocations are also
costly, with a total expense of 80,681inthisstudy(269 – 7,559perindividual).Themaincostfactorwastrackingtechnology(565,983 (adjusted median) and 65% of
all costs were recuperated from public support. Translocations can successfully conserve
individual carnivores and help supplement low-density populations locally. However, due
to its limited success, associated costs, and a high degree of variability in terms of
outcomes, the strategy is not a feasible standard response to human-carnivore conflict. It is
best reserved as a last-resort tool for the selective management of few individuals from
highly endangered species. Where it is necessary, rigorous candidate and recipient area
selection can improve outcomes significantly. Wildlife managers should predominantly
aim at improving tolerance of large carnivores in unprotected, multi-use landscapes,
thereby reducing the number of indiscriminately captured animals
