[en] Zakouma National Park is situated in the south-east of Chad Republic and covers more
than 3 000 km2. Rehabilitated in 1989, it is certainly one of the best-preserved wildlife
sanctuaries in Sahelian Africa. Aerial census shows that most of its original fauna is still
present, making the Park an exception in the region despite the recent troubled history of this
country. Total population estimates of elephants, buffaloes and topis are given and distribution
maps are presented for eleven species. Results are compared with two previous estimates.
Except for the ostrich and perhaps the warthog, probably in regression, the populations of two
species are stable (hartebeest and giraffe) while the others are clearly increasing (buffalo, topi,
elephant and roan antelope). Those encouraging results are the consequence of the remoteness
of the park, wich is far from any big town, and also overflooded and isolated during the wet
season. Those facts contribute to maintain the human pressure at a sustainable level.
