Namibian Wildlife Surveys archive
This archive of reports of wildlife surveys in Namibia aims to:
- provide easy public access to published information and statistics
- enable easy stakeholder access to recent and historical data on wildlife populations
- provide a comprehensive archive of wildlife survey reports in Namibia
Public access to information is a vital component of ensuring community engagement in prevalent issues. Wildlife surveys are critical to determine the health of wildlife populations and determine trends over time to guide conservation and management actions.
Wildlife surveys are done for different species using methods that are suited to counting them (e.g. by air or road) in their natural habitats. Such surveys need to be repeated over time to detect long-term trends and inform conservation managers. The Namibian government, non-governmental organisations and private reserves all conduct regular surveys covering different parts of Namibia and targeting different species. This archive will thus serve as a repository of our collective knowledge of the trends and status of a variety of species occurring throughout Namibia.

The Ongava Research Centre is collecting images of cheetahs and leopards in Etosha National Park in order to provide reliable population estimates of these predators for the first time. Did you know that there is no reliable information about the number of cheetahs and leopards in the Etosha National Park? Last year, the Ongava Research Centre (ORC) therefore called on visitors to the national park to take part in a survey by sharing pictures and sightings of cheetahs and leopards.

So, how many elephants is too many elephants? It's a question people have wrestled with for ages. Kruger National Park, home to one of Africa's largest elephant populations, has seen their numbers grow from just a handful in the early 1900s to over 31,000 by 2020. That's a lot of elephants! A recent study using smarter aerial surveys and fancy math gives us a more clear picture of just how fast these gentle giants are multiplying. Turns out, since 2013, their numbers have been growing by about 5.3% each year.

Evidence of a decline in the range of elephants is provided by the survey carried out by Viljoen in 1982. The map in fig. 31 is somewhat misleading as all survey blocks in which elephants were seen are shaded even though elephants were unlikely to have been spread throughout the blocks. However, the occurrence of carcasses (cross-hatched areas) in areas where elephants are no longer found indicates a decrease in the range. Since the 1980s, the elephant counts have shown a consistent increase in the population (Fig. 32).

The study sites are covered systematically, by tracking their spoor and setting out bait, to capture and mark all individual leopards and lions. Study animals are immobilised following standard procedures described by our earlier studies and conform to international veterinary standards. All leopards and 80% of lions are radio collared and lions are marked with permanent hot brands. The age of lions and leopards are determined from tooth wear. Radio-collared animals are located with the use of a fixed-wing aircraft.
