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.

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.

Gondwana Collection Namibia 2020. Gondwana Canyon Park Game Count 2020.

The year’s results show a significant decrease in animals counted (-37%) and overall population estimate (-19%). The game harvesting operations done in the preceding year would have contributed to the lower game numbers. The northern sections of the park (zone 6, 7, 8 and 9) received the most rain and thus an overwhelming majority (53%) of the animals were counted in this area. For the first time in 8 years the park’s modelled carrying capacity is higher than the total grazer biomass (stocking rate).

Gondwana Collection Namibia 2020. Gondwana Kalahari Park Game Count 2020.

This year's game count results showed the drastic decrease in game numbers, with gemsbok numbers being down 86% compared to 2019 and plains zebra and wildebeest down 93% and 97% respectively. Red hartebeest have all disappeared from the park as most of them died, a few were harvested, and a few got onto neighbouring properties. Only giraffe managed to increase, as 4 more calves were born over the last year, bringing the total to 22. Naturally, successful reproduction in the other game species over the past season has been very low.

Gilbert NA, Clare JD, Stenglein JL, Zuckerberg B 2020. Abundance estimation of unmarked animals based on camera-trap data. Conservation Biology 35 (1) 88-100

The rapid improvement of camera traps in recent decades has revolutionized biodiversity monitoring. Despite clear applications in conservation biology, camera traps have seldom been used to model the abundance of unmarked animal populations. The goals of this review are to summarize the challenges facing abundance estimation of unmarked animals, present an overview of existing analytical frameworks, and provide guidance for practitioners seeking a suitable method.

Loonam K, Ausband DE, Mitchell MS, Robinson HS 2020. Estimating abundance of an unmarked, low‐density species using cameras. The Journal of Wildlife Management

Estimating abundance of wildlife populations can be challenging and costly, especially for species that are difficult to detect and that live at low densities, such as cougars (Puma concolor). Remote, motion‐sensitive cameras are a relatively efficient monitoring tool, but most abundance estimation techniques using remote cameras rely on some or all of the population being uniquely identifiable. Recently developed methods estimate abundance from encounter rates with remote cameras and do not require identifiable individuals.

Thomson G 2020. Counting Cats - An updated national leopard survey for Namibia. Conservation and the Environment in Namibia (2020)

Leopards are among the most enchanting big cats in the world. Their beauty, raw power and elusiveness have fascinated humans through the ages. Our fascination with leopards is a double-edged sword for the big cat, however. The value we place on seeing this beautiful big cat draws tourists and provides funding for conservation.

Simmons R, Kolberg H, Braby R, Erni B 2015. Declines in migrant shorebird populations from a winter-quarter perspective: State-Space Models for Shorebird Trends . Conservation Biology 29 (3) 877-878

Many long-distance migrating shorebird (i.e., sandpipers, plovers, flamingos, oystercatchers) populations are declining. Although regular shorebird monitoring programs exist worldwide, most estimates of shorebird population trends and sizes are poor or nonexistent. We built a state-space model to estimate shorebird population trends. Compared with more commonly used methods of trend estimation, state-space models are more mechanistic, allow for the separation of observation and state process, and can easily accommodate multivariate time series and nonlinear trends.

Gibson DSC, Craig GC 2015. Aerial survey of elephants and other wildlife in Zambezi Region, September/October 2015.

An aerial survey of wildlife and domestic livestock took place in Zambezi Region from 25 th September to 4 th October 2015. A total area of 17474km2 was sampled at an average intensity of 13%. The estimates of numbers of each species are tabulated below. The number of elephants estimated has decreased since the 2014 survey, although the change is notstatistically significant. However there has been a very highly significant increase in the estimated number of elephant carcasses since 2014. Other observations suggest that illegal hunting of elephants continues to take place in the…

Gibson DSC, Craig GC 2015. Aerial survey of elephants and other wildlife in Khaudum National Park and neighbouring conservancies, October 2015.

An aerial survey of wildlife and domestic livestock took place in the Khaudum National Park and its neighbouring conservancies from 6 th to 14 th October 2015. A total area of 12851km2 was sampled at an average intensity of 9%. The focus of the survey was on obtaining good estimates of elephant numbers. Other species were recorded although it is likely that their numbers would be underestimated (Craig and Gibson, 2013a).

2015. Terms of Reference: Aerial survey and census of elephant and other large herbivore populations in the Zambezi Region, Khaudum National Park and Nyae Nyae Conservancy .

The work of this consultancy continues an overview of elephant populations that were recently surveyed in the Zambezi Region (Caprivi), Khaudum National Park and Nyae Nyae. That survey was a response to the escalating killing of elephants across the African elephant range (CITES 2012)1 including southern Africa. This illegal activity is being driven, both internally within Africa and externally by an illegal wildlife trade. Such trade has become highly criminalized involving corrupt politicians, private sector syndicates and inept &/or corrupt bureaucrats.

Hanssen L, Singwangwa M, Kukuwa V 2015. Camera trap survey to determine the status of leopards in the Mudumu-North Complex, Zambezi Region, Namibia Report July 2015.

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.
