Many of the projects and working groups which NNF supports are carrying out a range of research projects. In addition, recent research projects with which NNF has been involved include:
|The river systems of north-east Namibia were surveyed during August 2004 using a combination of aerial census and boat census to count hippopotamuses, floodplain ungulates, crocodiles, and some large birds. A total of 9,515 animals were counted, including 1,387 hippos and 538 lechwes. The total crocodile population for the north-east river systems consists of some 2,200 crocodiles of greater than 2 m in length, and some 9,300 crocodiles of less than 2 m, with many of the latter being small animals of less than 1 m and likely to suffer high rates of mortality. The major component (87%) of the >2 m crocodile population occurs in the Kwandu-Linyanti-Chobe system, and this is the system that also has the largest proportion of young animals.
