Migration of 6m antelope in South Sudan dwarfs earlier data for world’s greatest, aerial examine reveals

An in depth aerial survey in South Sudan has revealed an infinite migration of 6 million antelope – the biggest migration of land mammals anyplace on Earth. It’s greater than double the scale of the celebrated annual “nice migration” between Tanzania and Kenya, which entails about 2 million wildebeest, zebra and gazelle.

“The migration in South Sudan blows another migration we all know of out the water,” stated David Simpson, wildlife NGO African Parks’ park supervisor for Boma and Badingilo nationwide parks, which the migration strikes between and round. “The estimates point out the huge herds of antelope species … are nearly thrice bigger than east Africa’s nice migration. The size is actually awe-inspiring.”

The animals throughout the area have endured regardless of a long time of civil conflict and instability in South Sudan.

In 2007, a Wildlife Conservation Society survey advised South Sudan’s migration concerned about 1.3 million animals. However African Parks, which manages Boma and Badingilo nationwide parks within the south-east of South Sudan on behalf of the federal government, has been capable of present a extra correct depend utilizing improved know-how and assessing a extra complete space. Two planes have been kitted out with cameras programmed to take a photograph each two seconds. This produced 330,000 photos, which have been studied by College of Juba graduates utilizing software program to depend the wildlife.

“Seeing these animals right here at such scale is one thing I might have by no means fathomed nonetheless existed on the planet,” stated Mike Fay, African Parks’ panorama coordinator for Boma and Badingilo. “From the air, it felt like I used to be watching what Earth might need been like millennia in the past, when nature and people nonetheless existed collectively in steadiness.”

South Sudan president Salva Kiir Mayardit stated that the depend made the nation’s migration “primary on this planet,” including that “as South Sudan continues to develop we’re dedicated to remodeling the wildlife sector right into a sustainable tourism business.”

From 28 April to fifteen Could 2023, the pilots and observers flew over an space of 122,774 sq km – nearly the scale of Greece – taking in the whole recognized vary of the antelope species within the Boma-Badingilo Jonglei panorama. They lined some areas that had by no means been surveyed. In addition to antelope, the surveyors documented different species together with lions, giraffes, buffalo and elephants.

“Probably the most troublesome problem is organising the aerial survey gear on the planes, so the sector of view is right and the calibration is exact and correct,” Fay stated. “It’s extraordinarily harmful flying low-level with large birds, like vultures, within the air across the aircraft, and it’s intense flying for 4 hours and counting constantly day-after-day for weeks.”

The estimates indicated 5 million white-eared kob, just below 300,000 tiang, 350,000 Mongalla gazelle, and 160,000 bohor reedbuck, the 4 species of antelope totalling just below 6 million. Fay stated that determine signifies that “this nice Nile migration of antelope is the biggest on Earth, in keeping with our knowledge, dwarfing another recognized land mammal migration on the planet”.

The nice Nile migration is a year-round motion of animals from the south-west to the north-east, passing into Gambella in Ethiopia and again once more. It’s most likely pushed by the supply of fine grazing situations.

As a part of the examine, 126 animals throughout 12 species have been collared to measure the distances they travelled: 11 collared white-eared kobs, probably the most quite a few antelope within the panorama, have been tracked protecting roughly 2,000km (1,250 miles) every. South Sudan’s isn’t the longest land mammal migration on Earth – the caribou migration in Alaska, at 3,200km (2,000 miles), is longer – however it’s a comparable distance to the good migration between Tanzania and Kenya, which incorporates the famend Mara River crossing. And, whereas South Sudan’s is probably the most quite a few massive mammal migration, its numbers are dwarfed by Zambia’s annual bat migration, wherein 10 million straw-coloured fruit bats fly from west Africa to Kasanka nationwide park.

The examine’s findings are “a gamechanger for conservation efforts in South Sudan”, Simpson stated, and will turn into “one of many best conservation alternatives on the planet”.

South Sudan isn’t thought-about protected for worldwide tourism, however such an unlimited wildlife spectacle means “the potential for tourism is immense”, says Simpson. “Having the world’s largest land mammal migration might put South Sudan on the map as a must-visit ecotourism vacation spot. However the migration’s present vital worth is meals safety for native communities.”

The Boma-Badingilo Jonglei panorama is residence to quite a few folks, lots of whom stay off the land. In addition to revealing the dimensions of wildlife within the panorama, the survey revealed threats to the migratory animals and the human communities that depend on them, Simpson stated, together with “the growth of roads, agriculture, charcoal manufacturing, commercialisation”. “These actions can result in habitat loss, useful resource depletion and disruption of migration routes, finally threatening the survival of the migration and the livelihoods of native folks,” he stated.

“By making certain the well being of the ecosystems the migration relies on, the livelihoods of individuals throughout the migration panorama will be secured.”
