Giraffe might not be considered a migratory animal in the classic sense, but when seasonal variation in habitat suitability occurs over spatially segregated habitat types, migratory movement patterns can emerge. In Murchison Falls National Park, Uganda, this happens because of seasonal variation in phenology across different savanna types, and in Zakouma National Park, Chad, this happens largely because of seasonal flooding.
We recently teamed up with Global Initiative on Ungulate Migration (GIUM) to showcase these two populations of northern giraffe in the Atlas of Ungulate Migration. Including this on the list of mobile ungulates (illustrated with some really cool maps) will hopefully highlight the importance of connectivity and movement for the conservation of species like the northern giraffe.
As an aside, this is an interesting case of convergent inferences in movement ecology studies. Science is supposed to be reproducible, which is admittedly a challenge in complex ecological systems. In 2020, we published the first account of partial migration in the Murchison Falls National Park population, and in 2023, we published on the seasonal movements in the Zakouma National Park population. In both of these populations, the subsequent GIUM analyses were conducted by an independent group of researchers with an expanded telemetry dataset from the original publications. And in both cases, similar findings and ecological inferences were reached.
In a surprising discovery, our latest research in Uganda and Chad has revealed that Nubian and Kordofan giraffe exhibit seasonal migratory patterns. Mapping their movements with our partner, the Global Initiative on Ungulate Migration, shows giraffe traveling up to 60 km to find refuge from flooding and locate the best forage.
The recovery of giraffe and their movement patterns in Murchison Falls and the Greater Zakouma Ecosystem is a powerful testament to what happens when we invest in long-term conservation. While habitat loss and human impacts remain challenges, the ability of giraffe to roam across these connected landscapes gives us great hope for their future.
