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.

Brown LM, Ramey RR 2025. Status and distribution of desert-dwelling elephants in the Hoarusib, Hoanib, and Uniab River drainages, Kunene Region, Namibia.

We compiled data from our research (2006-2025) along with published accounts dating back to 1975 on the desert-dwelling elephant population in our study area of Skeleton Coast National Park and western Kunene region. This includes the Hoarusib River, Hoanib River, and Uniab River sub populations. Our analysis of the data reveal the profound influence that human-caused elephant mortality has had on the population over this time period. An initial precipitous decline occurred due to wartime poaching in the 1980s.

Brown LM, Ramey RR 2021. Status and distribution of desert-dwelling elephants in the Hoarusib, Hoanib, and Uniab River drainages, Kunene Region, Namibia. Final Version: Annual Research Report 2021, 31 December 2021.

The following data on elephants of the Hoarusib, Hoanib, and Uniab river drainages is based on exact counts of known individuals from our photo ID database.

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.

Brown LM, Ramey RR 2020. Status and distribution of desert-dwelling elephants in the Hoarusib, Hoanib, and Uniab River drainages, Kunene Region, Namibia. 2019 Annual Research Report (NCRST Research Permit RCIV00042018, Authorization # 20190519) 9 March 2020.

In the Hoarusib River, a third of the remaining elephant population was lost in 2019. From a total of 16 elephants in 2018, there are now only 11 that remain. All the elephants were in poor condition due to the extensive drought that has affected the region and killed most of the cattle. The ongoing drought, in combination with continuing human-wildlife conflict, has had a serious impact on elephants and other wildlife species as well.

de Rock P, Elwen SH, Roux JP, Leeney RH, James BS, Visser V, Martin MJ, Gridley T 2019. Predicting large-scale habitat suitability for cetaceans off Namibia using MinxEnt. Marine Ecology Progress Series 619 149-167

Knowledge of the occurrence and distribution of cetaceans is particularly important for conservation and management, but is still limited within Namibian waters. We collated 3211 cetacean records from the Namibian Exclusive Economic Zone (EEZ) for the period 2008 to 2016 and applied the principle of minimum cross entropy (MinxEnt) to predict habitat suitability. MinxEnt is a generalised form of maximum entropy modelling that allows incorporation of additional information such as sampling bias.

Mendelsohn J, Haraes L 2018. Aerial census of Cape Cormorants and Cape Fur Seals at Baía dos Tigres, Angola. Namibian Journal of Environment (2) 1-6

A total of 250,786 Cape Cormorants, of which 16,038 were individuals on nests in 349 colonies, and 15,831 Cape Fur Seals were counted during a complete aerial photographic census of the island of Tigres and part of the adjacent coast in Angola in March 2017. Such a concentration of birds and seals and the large number of breeding Cape Cormorants highlights the need to protect Tigres and its rich surrounding waters. Keywords: aerial census, Arctocephalus pusillus pusillus, Baía dos Tigres, Cape cormorant, Cape fur seal, Phalacrocorax capensis.

Ramey RR, Brown LM 2018. Status and distribution of desert-dwelling elephants in the Hoarusib, Hoanib, and Uniab River drainages. 2018 Annual Research Report (Research and Collection Permit # 2298/2017) 10 February 2019.

We compiled data from our research (2006-2018) along with published accounts dating back to 1975 on the desert-dwelling elephant population in our study area of Skeleton Coast National Park and western Kunene region. This includes the Hoarusib-Hoanib, and Uniab subpopulations. Our analysis of the data reveal the profound influence that humancaused mortality has had on the population. An initial precipitous decline occurred due to wartime poaching (1980s).

Mendelsohn J 2014. Observations on the movements and home ranges of Hartmann’s Mountain Zebras and Oryx in the Greater Sossusvlei-Namib Landscape, July 2014.

This document provides a summary of information on the movements and locations of 9 Hartmann’s mountain zebra and 9 oryx in the Greater Sossusvlei-Namib Landscape (GSNL). Each animal was fitted with a GPS tracking device on the 22nd or 23rd of November 2013. The locations of the animals were then recorded every 5 hours. This provided over one thousand locations for each animal during the 7 months from November 2013 to the 26th of June 2014, the date chosen as a cut-off for this review.

Mendelsohn J, Mendelsohn M 2014. Observations on the movements and home ranges of Hartmann's Mountain Zebras and Oryx in the Greater Sossusvlei-Namib Landscape, December 2014.

This document provides an update of information on the movements and locations of 9 Hartmann’s mountain zebra and 9 oryx in the Greater Sossusvlei-Namib Landscape (GSNL). The report covers one year: from the last days of November 2013 when the transmitters were fitted to the end of November 2014. A previous report reviewed data collected during the first 7 months up to the 26th of June 2014. The locations of the animals were recorded every 5 hours up until late July 2014 when the recording frequency was adjusted to one signal per day recorded at approximately 06h00.
