For the first time since local extinction in 1996, Nubian giraffes have returned to Pian Upe Wildlife Reserve in northeastern Uganda. Fifteen of this vitally endangered animals were moved over 400 km from Murchison Falls National Park in October 2019.

The 11 female and 4 male giraffes are aged two to four: "We chose younger giraffes because they have a longer reproductive lifespan," says Robert Aruho, a doctor of Uganda Wildlife Authority (UWA), who let the move.

Northern Uganda is home to Nubian giraffes. They have large, rectangular blotches (矩形斑点) set irregularly against a cream background. The lower legs are noticeably white and not patterned. Pian Upe's grassy land held large numbers of giraffes in the 1960s before conflict in the Karamoja region saw them hunted illegally. "The habitat is perfect, and effective anti-hunting measures are now capable of supporting at least 700 individuals," explains Aruho.

Nubian giraffes are Uganda's only giraffe species and most of them inhabit Murchison Falls. "We can't have all our eggs in one basket," Aruho says, "We have a unique opportunity to act now to prevent them dying out."

Back in 2015, the UWA moved 15 Nubian giraffes from Murchison Falls to Lake Mburo National Park. After that, 9 of the 10 females quickly became pregnant. From a little over 300 Nubian giraffes in the mid 1990s in Uganda there are now about 1,650. A further 25 giraffes will move from Murchison to Pian Upe in October 2020.

"In Uganda we continue to work closely with the UWA to increase numbers and populations of threatened Nubian giraffes. Boosting existing populations is vital for securing their future in the country," Aruho says.
