Operation Sahel: translocation and reintroduction of West African giraffe (Giraffa camelopardalis peralta) in Niger.

The West African giraffe (Giraffa camelopardalis peralta), a subspecies of the northern giraffe (G. camelopardalis), naturally only inhabited one unprotected area in Niger. West African giraffe are a conservation success story as their population has grown from ~ 49 individuals to > 600 as a direct result of efforts by the Niger government and NGOs. Along with improved legislation, enhanced monitoring, and community engagement, establishing a satellite population within their historic range has been a major success. Giraffe translocations are technically and logistically difficult, and may require immobilisations, which add additional challenges. Such translocations are commonly undertaken in southern and East Africa with specialised equipment and experienced teams. However, with good planning and preparation, giraffe can be translocated with a small, effective team and locally constructed equipment. This case report describes the translocation of 12 West African giraffe (eight female and four male) to the Gadabedji Biosphere Reserve, Niger, using locally constructed equipment. All giraffe were immobilised in the field and taken to a temporary holding boma for acclimatisation. The translocations took place in 2018 and 2022, interrupted by the COVID-19 pandemic. The giraffe spent between 24 hours and six weeks in the holding boma, and the former group received a low-dose of water-based perphenazine for tranquillisation and possible anxiolytic effects. Transport was by road using a modified 20-foot open-topped shipping container with strategic stops for feeding and rest. Giraffe were hard released into the reserve. No mortalities occurred during the operation and post-translocation; five calf births were recorded by the end of 2023.
