Site description The site includes Boma National Park and the adjacent Boma hills. The area is located in the south-east of Sudan close to the Ethiopian border, south-east of the town of Pibor Post. It lies between the rivers Kangen to the west and Oboth in the north-east and from the Kurun river and the provincial boundary in the south to the Guom swamps in the north. Two-thirds of the park is flat flood-plain, punctuated by a number of isolated hills, rising to undulating terrain in the east to reach the Boma plateau at c.1,100 m. In the south-east the Boma hills rise above the plateau and are drained eastwards into the Oboth and Akobo rivers and thence, eventually, into the Guom swamps. The western part of the park drains into the Kangen river. The western plains support open grassland of Hyparrhenia, Pennisetum, Sporobolus and Echinochloa spp., while eastern parts are covered with woodland dominated by Combretum and Ficus spp. In patches around the isolated hills are areas of dense thicket dominated variously by Ziziphus spp., Acacia seyal, A. zanzibarica, A. drepanalobium and A. fistula, while there are small areas of evergreen forest on the western slopes of the Boma hills. The site is located a little way south of Gambella National Park in Ethiopia (IBA ET035).
