The current study was undertaken to determine long-term population trends (33 years) of ungulate species in the Waterberg National Park (WNP), Namibia, using aerial and waterhole counts of ungulates during the years 1980–2013.We tried to establish how rainfall influences the multi-species population dynamics. During this period sixteen ungulates species were recorded. Among these, eight have shown an increase in numbers during the years 1984–2013, six other decreased, and populations of two other species remained stable. Roan and sable antelope, kudu and warthog were fairly common (with 5–12% of all ungulates recorded). White rhino, black rhino, giraffe, and gemsbok were classified as uncommon (together 11.9%), whilst the remaining eight species were rare (together 1.9%). The eland population showed a weak positive relationship with the annual average rainfall between the years 1981–2013, whereas population sizes of kudu, sable, gemsbok and roan showed a weak negative relationship with the amount of rain. No relationship was detected in giraffe, buffalo and hartebeest populations. We conclude that, irrespective of water supplementation, ungulate densities are to a large extent controlled by rainfall.
