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.

Longden EG, Elwen SH, McGovern B, James BS, Embling CB, Gridley T 2020. Mark-recapture of individually distinctive calls-a case study with signature whistles of bottlenose dolphins (Tursiops truncatus) . Journal of Mammalogy 101 (5) 1289-1301

Robust abundance estimates of wild animal populations are needed to inform management policies and are often obtained through mark–recapture (MR) studies. Visual methods are commonly used, which limits data collection to daylight hours and good weather conditions. Passive acoustic monitoring offers an alternative, particularly if acoustic cues are naturally produced and individually distinctive. Here we investigate the potential of using individually distinctive signature whistles in a MR framework and evaluate different components of study design.

Goelst C, Moeller M, Kilian W 2018. Etosha National Park Carnivore Monitoring Project Update, Unofficial Report Re: Lion GPS-Satellite Monitoring, 2018 Lion Population Call-Up Survey.

Carnivore populations face threats from increasing human populations and rapidly diminishing, suitable habitat. Large carnivores such as African lions (Panthera leo) commonly attack livestock on lands adjacent to protected areas. This can lead to human-wildlife conflict (HWC) events that result in retaliatory lion killings. Conflict is a primary driver of wild lion population declines which are estimated to have decreased by 43% in the last 20 years.

Marker LL, Dickman AJ, Mills MGL, Jeo RM, MacDonald DW 2008. Spatial ecology of cheetahs (Acinonyx jubatus) on north-central Namibian farmlands . Journal of Zoology 274 226-238

Knowledge of a species' ranging behaviour is both fundamental to understanding its behavioural ecology and a prerequisite to planning its management. Few data exist on the spatial ecology of cheetahs Acinonyx jubatus outside protected areas, but such areas are particularly important to their conservation. Cheetahs on Namibian farmlands occupied exceptionally large home ranges, averaging 1651km2 (1594km2), with no detectable effect of sex, social grouping or seasonality.

Brown CJ, Meyer-Rust R 2004. Winter counts of wetland and floodplain birds in the Kwando River and floodplain system, Caprivi .

Human and, increasingly, elephant pressure on Namibia's wetlands and riparian belts are a major cause of conservation concern. Many wetland birds are listed in Namibia's Red Data Book (Simmons & Brown in prep) because of population declines caused by the degradation and destruction of wetland habitats, and because of high levels of disturbance. Good information on the status of major wetlands and their avifauna is important for their conservation management. Birds provide one of the best indicators of wetland health.

Brown CJ, Stander P, Meyer-Rust R, Mayes S 2004. Results of a Crocodile Crocodylus niloticus survey in the river systems of north-east Namibia during August 2004 .

This study has provided baseline data on crocodile numbers from aerial and spotlight counts. These data can be used with the results of future counts to determine population trends. The census has also provided information on their distribution of crocodiles in the Kavango and Caprivi regions. And third, it has resulted in the first population estimate for crocodiles in the north-east wetlands of Namibia.
