- Data packageData from: A note on the reestablishment of the cheetah population in the Pilanesberg National Park, South Africa(2020-11-25) Power, R. John; Dell, StephenThe establishment of protected areas is recognized as a means to conserve large mammal species, and cheetah (Acinonyx jubatus) conservation is well served by these protected areas. The Pilanesberg National Park (Pilanesberg) is one such reserve within the managed metapopulation. Here, we firstly document the reproductive success of a single reintroduced female cheetah and, secondly, discuss the population's recovery in the context of the managed metapopulation. In April 2014, Pilanesberg had three adult cheetahs; the newly reintroduced female and the coalition of two adult males. The focal study animal was this adult female that was initially held in a boma at Madikwe Game Reserve for ∼3 months and ‘hard released’ into Pilanesberg with a fitted satellite collar. She was monitored by the first and fifth authors on a daily and monthly basis by satellite and radio-telemetry, respectively; while all cheetahs were also monitored by opportunistic observations by tourists and guides.
- Data packageData from: Repatriating leopards into novel landscapes of a South African province(2021-02-05) Power, R. John; Venter, Leanne(1) Leopards are often translocated away from where they are caught as non-lethal human-wildlife conflict mitigation. It is alleged that leopards fail to settle where they are translocated to, owing to territoriality. We address the need to publish more accounts of successful repatriation of leopards, but also include novel applications aimed at orphans and confiscated leopards. (2) We satellite collared 16 leopards which included a mixture of relocated, and translocated leopards, of which the latter included conventional Damage Causing Animals (DCAs, viz 'problem animals'), orphans and confiscations. We determined standard home- range metrics and assessed home-range stabilisation as a means of determining site fidelity. Premature mortality and site infidelity, i.e homing back to origins, were considered failures. We looked at range stabilisation by examining successive monthly ranges against that of the preceeding month, i.e UDOIs. (3) Relocations turned out to be residents (~3 km, n=3), while they were immune to intervention, while translocations resulted in 50% success (n=12), which were invariably confiscated adults of unknown origin, and simulations of natal dispersals of orphans (~25 km, n =3). DCAs never settled where released (~90 km, n = 5). Resident leopards showed high monthly UDOIs, and for those translocated, a minimum of 0.15 was benchmarked to suggest range stability, which also reflected large spatial ranging. (4) Success in HR establishment was associated with landscapes which were unsaturated by other leopards, but anthropogenic threats still persisted, such that survival after a year was ~45%, but was not different to the normal background mortality of areas outside protected areas in the country. Operations are costly, particularly that to do with veterinary treatment, immobilisation, collars and temporary keeping, but such costs can be carried by public interest groups.
