Abstract : The Dinder National Park (DNP) was established in 1935 following the London convention of 1933, and in
1979 it was designated as biosphere reserve, one of only two in the Sudan. The global significance of the DNP is that it
falls between two important ecological zones the (Sudano-Sahelian and the Ethiopian). The DNP was designated as a
Ramsar site in 2001. The Mayas are oxbow lakes along the meandering rivers, they are subject to floods and contain
green fodder and water up to the end of the dry season. The park supports 27 large mammals, bats and small mammals,
more than 160 species of birds, 32 fish species, reptiles and amphibians. In addition there are about 58 species of shrubs
and trees (Higher Council for Environment and Natural Resources, 2001). Hashim and Nimir (1979) observed that there
were fluctions in the structure and densities of animals in the park during the previous years, and these fluctions were
attributed to habitat deterioration, poaching and encroachment of human activities. As human population increases,
demand for food also increase and this exerts pressure on the land and its resources. Wildlife ecosystem in Sudan is
composed of biosphere reserves, national parks, game reserves and sanctuaries. In 1983 it was reported that there were
52 major wildlife species in northern Sudan while in 1991 a list of 83 was produced, Major species were distributed in
19 protected areas all over the Sudan. In Dinder National Park showed that 27 mammals and also several species of
small mammals, and partial summer lists of 115 birds 14 snakes and scorpions, and 108 species of insect and 26 fish
species are recorded. About 49 common tree species and shrubs (of which eight endangered) and 195 common
herbaceous plants are identified (GOS and HCENR, 2006). Dinder National Park support a large population of animals
during the dry season and the lesser number during the wet season (Dasmann,1972). A systemic animals census had
been conducted by Minga (1971) on nine of the principle of Mayas, he counted a total of 5613 large game animals
during the period March to April 1971. Dasmann (1972) used aerial counts in August, counted 49 animals outside the
park include reedbuck, roan antelope, tiang and ostrich. Although sight of animals was difficult because of the dense
wooded vegetation. Dropping counts and road counts of the large herbivores conducted by Wildlife Research Center
(WRC) in the most of the principle Mayas during 1971-1994 (Abdel Hameed 1994) showed that generally there was a
decline trend in the total number of the animals using the Mayas.
