Boma–Badingilo Migratory Landscape
World Heritage Site in South Sudan
Boma–Badingilo Migratory Landscape or Great Nile Migration Landscape (GNML) is the largest land mammal migration in the world. It features seasonal movement of millions of antelope, such as white-eared kob (5,000,000), Mongalla gazelle (350,000), tiang (300,000), and Bohor reedbuck (160,000), in search of water.
Once thought to not exist anymore because of years of conflict in South Sudan, aerial views from helicopters and airplanes have made the migration visible in an area where virtually no roads exist. The vacant areas border tribes of indigenous people. The terrain is made up of savanna and woodland floodplain under threat from agricultural production as well as oil, gas and mining developers. The known range of the migration cover 122,774 square kilometres (47,403 sq mi), stretching from South Sudan's Bandingilo and Boma national parks into Ethiopia's Gambella National Park.
The migration occurs from January to June, with the pattern reversed from November to January. In numbers and spatial extent, the Great Nile Migration surpasses that of the Serengeti's wildebeest (2,000,000)) by more than double. In 2021, it was estimated the migration included 1 million kob and 200,000 tiang. A 2023 survey found it may be the largest migration, including 5 million white-eared kob, 350,000 Mongalla gazelle, 300,000 tiang, and 160,000 bohor reedbuck.

Why this record matters
The phrase “world Heritage Site in South Sudan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q60848196. Authority coordinates are 6.514, 32.959. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2021 and 2023.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
