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.

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.

Martin MJ, Gridley T, Roux J-P, Elwen SH 2020. First abundance estimates of Heaviside's (Cephalorhynchus heavisidii) and Dusky (Lagenorhynchus obscurus) dolphins off Namibia using a Novel Visual and Acoustic Line Transect Survey . Frontiers in Marine Science

Knowledge of a population’s abundance is of primary importance for conservation management. However, robust estimates of abundance are often difficult to obtain, especially for cetaceans which spend most of their lives submerged. Cetacean abundance is commonly estimated using aerial or vessel-based line transect surveys and distance sampling methods. During 2012–2014, the first line transect surveys to estimate cetacean abundance were conducted in Namibian waters.

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.

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).

Weise FJ, Vijay V, Jacobson AP, Schoonover RF, Groom RJ, Horgan J, Keeping D, Klein R, Marnewick K, Maude G, Melzheimer J, Mills G, van der Merwe V, van der Meer E, Van Vuuren RJ, Wachter B, Primm SL 2017. The distribution and numbers of cheetah (Acinonyx jubatus) in southern Africa . PeerJ e4096

Assessing the numbers and distribution of threatened species is a central challenge in conservation, often made difficult because the species of concern are rare and elusive. For some predators, this may be compounded by their being sparsely distributed over large areas. Such is the case with the cheetah Acinonyx jubatus. The IUCN Red List process solicits comments, is democratic, transparent, widely-used, and has recently assessed the species.
