Boma National Park

Boma National Park is a protected area in eastern South Sudan near the Ethiopian border. It was established in 1977 and covers 22800 km2 of grasslands and floodplains.

The park is in the Somali-Maasai and Sudano-Guinean biomes. The southern part of the park has extensive short grasslands and acacia bush. Woodland, mostly the Combretum and Ficus species, is in the eastern part. The western part is open grassland. Wetlands can be found, and though most are seasonal there are some permanent waterholes. The largest is the Juom Swamp in the north.

In August 2022, African Parks signed a 10-year renewable agreement with the government of South Sudan to restore Boma and Bandingilo National Parks and realise their potential as premier wildlife destinations.

Wildlife
The world's second-largest annual animal migration takes place when multiple species of antelope, including Bohor reedbuck, tiang, and white-eared kob, move between Boma National Park and Bandingilo National Park. In 2021 it was estimated the migration included 1 million kob and 200,000 tiang. The migration happens from January to June. The animals move from Bandingilo into Boma and the Gambella National Park in Ethiopia. Then the pattern is reversed from November to January.

The park is an important refuge for white-eared kob, tiang, and Mongalla gazelle. Other large mammals are buffalo, elephant, African leopard, Nubian giraffe, oryx, Lelwel hartebeest, Northeast African cheetah, common eland, maneless zebra, waterbuck, Grant's gazelle, lesser kudu, bongo, giant eland, and Nile lechwe. It is also an important bird area; avifauna includes Ruppell's vulture and the black-chested snake eagle. The neighboring Gambella National Park in Ethiopia protects similar species.

Since 2005, the protected area is considered a lion conservation unit together with Gambella National Park.

White-eared kob
The most prominent species of the Boma National Park is the white-eared kob (Kobus kob leucotis) antelope. A UNEP study reports that the white-eared kob is found mostly to the east of Nile River in South Sudan within the clay plains and wetlands; though occurring in substantial numbers in Boma National Park, it is reported to be found more outside the protected area. Its migration route and population during the summer and monsoon seasons have been recorded. Its migration route over the dry and wet seasons, which is dictated by the variation in rainfall and flooding from year to year, extends over 1600 km; it encompasses different ecoregions in various tribal belts, and exposes the species to hunting threats. In comparison to the wet season count of 680,716 in 1980 (849,365 in dry season), the UNEP survey of 2001 reported only 176,120 during the wet season (although the two studies are not directly comparable).

Conservation
The wildlife in this park has provided bush meat, which is not only a dominant food need for many people of South Sudan, but also an avenue of illegal trading supported by wildlife hunting that has caused biodiversity damage. The park accounts for the greatest concentration of wildlife in the country, particularly of mammals.

African Geographic reported in 2021 that the decades-long conflicts in the region have caused conservationists to be unable to monitor the effects to animal populations and habitats. Additionally there is minimal infrastructure and limited access to the area. Once African Parks began management, they sent aerial surveys to begin estimating population numbers. Additionally 126 individuals from 12 different species were fitted with GPS tracking collars.
