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.

Four species of otter (Carnivora: Mustelidae) occur in Africa, of which the African clawless otter (Aonyx capensis) and spotted-necked otter (Hydrictis maculicollis) are known to occur in Namibia, although very little is known about their biology and distribution. Both species are listed as Near Threatened by the IUCN Red List of Threatened Species because of a reported decline in their numbers.

Accurately estimating hippopotamus (Hippopotamus amphibius) numbers is difficult due to their aggressive nature, amphibious lifestyle, and habit of diving and surfacing. Traditionally, hippos are counted using aerial surveys and land/boat surveys. We compared estimates of numbers of hippos in a lagoon in the Okavango Delta, counted from land to counts from video taken from a DJI Phantom 4TM drone, testing for effectiveness at three heights (40 m, 80 m, and 120 m) and four times of day (early morning, late morning, early afternoon, and late afternoon).

As part of the Kavango-Zambezi Transfrontier Conservation Area (KAZA TFCA) the Mudumu Complexes of the east Zambezi Region of Namibia are important areas for wildlife connectivity and dispersal. The national parks of the east Zambezi Region, i.e. Mudumu and Nkasa Rupara, are too small to maintain viable populations of some wildlife species, which depend on being able to move across a network of landscapes, such as the conservancies and woodland areas to connect to protected areas in neighbouring countries such as Angola, Botswana and Zambia.

Areas surveyed: The Okavango River in Namibia, from just northwest the bridge on the Trans-Caprivi highway south to the Botswana border; the entire length of the Kwandu-Linyanti-Lake Liambezi-Chobe system, including the Mamili National Park; and the Zambezi river for its entire length on Namibia's border, including parts of the adjacent East Caprivi floodplains.
