Current Projects:
 Rhinos – We have been investigating the genetic relationships between the individuals in our resident populations of both black rhino (Diceros bicornis bicornis) and southern white rhino (Ceratotherium simum simum) in order to determine their lineage. We extract DNA from both dung and tissue samples at ORC, and then, in collaboration with the University of Cape Town, are apply parentage analysis to assign calves to their correct parents. In this way we hope to be able to assess the genetic fitness of the population and also to advise an optimum population management plan to avoid excessive inbreeding.

 Lions – The density of lions on Ongava is more than five times that in neighbouring Etosha National Park, yet the boundary with the bigger park is permeable to lions – they can move (with some effort) between the areas. Why are they here? Almost certainly due to increased prey density and a favourable habitat. The result is that Ongava has a complex and fragmented lion population, with effectively nomadic individuals, male coalitions and even prides moving through the reserve amongst other more resident lions. The population is also dominated by males, since they are generally more mobile. We believe that this results in very dynamic home ranges and probably high levels of infanticide as males compete for the right to sire cubs. We are investigating the dynamics of lion movements and social structures using GPS collars.
 Carrying Capacity – Our broadest project revolves around the general carrying capacity of the reserve, and how we measure, model and manage animal populations with that in mind. A crucial aspect to consider here is what impact predation has upon the herbivore populations. To assess that, we need to know with some accuracy (or at least repeatability) the numbers of all significant species on the reserve (herbivores and carnivores). To determine this, we are using a range of counting techniques (e.g. aerial surveys, waterhole counts, camera traps) and employing latest GIS methodologies to facilitate our analyses.
 Other projects – We have recently completed a pilot reptile and amphibian survey on Ongava under the guidance of Dr. Mark O’Shea. A total of 82 specimens across 31 species were captured and identified during the survey, of which 3 species were amphibians. The distribution of reptile species was 13 snakes, 13 lizards and 2 chelonians. During the survey we were fortunate enough to encounter a specimen of the extremely rare Anchieta’s dwarf python (Python anchietae). Ongava also has a breeding population of Black-faced impala Aepyceros melampus petersi, which is a slightly larger form of impala, and classified by the IUCN as vulnerable. There are thought to be fewer than 4000 remaining individuals, with Ongava’s population of close to 400 being one of the most important outside of Etosha.

About Namibia's Black Rhino...
The original range of this larger, straighter-horned and more arid-adapted subspecies, Diceros bicornis bicornis included Namibia, southern Angola, western Botswana and south-western South Africa.
