DNP is a national park and biosphere reserve in eastern Sudan. The park is home to 27 species of large mammals such as leopard, cheetah, more than 160 bird species, 32 fish species, and small mammals, bats, reptiles, and amphibians.
Dinder National Park is ecologically significant because it falls on the ecotone between the Sahel and Ethiopian Highlands ecoregions. It contains three distinct ecosystems: Riverine - riparian zone, Woodland, and
Maya (oxbow lake).
The ecology of the park is threatened by encroachment from cattle herders who are being displaced from their traditional grazing lands by the expansion of crop agriculture, through the fundamental cause of expanding regional population. Populations of migrant grazers, including tiang, Roan, waterbuck and reebuck, are under additional pressure as land outside the park that they migrate across has been converted to farmland.
Game counts between 1971 and 2001 have shown a precipitous decline in most large mammal species, with the population of waterbuck falling by 85%, reedbuck by 72%, and oribi by 68%. Other species have been extirpated in Dinder since was gazetted, including African bush elephant, black rhinoceros, hippopotamus, tora hartebeest, Nubian giraffe, Soemmerring's gazelle, and the Nile crocodile.
The park can be reached by road from Khartoum, a distance of 290 miles (470 km). Its headquarters are at Khartoum.
Vegetation in the park consists of thornbush savanna in the north and woodland in the south; along the riverbanks there are palm or gallery forests and swampy areas.
