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.

Elwen SH, Leeney RH, Gridley T 2019. Abundance estimates of an isolated population of common bottlenose dolphins Tursiops truncatus in Walvis Bay, Namibia, 2008–2012 . African Journal of Marine Science (41) 61-70

The coastal population of common bottlenose dolphins Tursiops truncatus found in Namibia is regionally isolated and unique. This population faces several potential anthropogenic threats, especially in Walvis Bay, including boat-based tourism, a commercial harbour undergoing expansion, and aquaculture for oysters and mussels. Between 2008 and 2012, 238 boat-based surveys were conducted, resulting in 170 encounters with bottlenose dolphins. Overall, group sizes varied from 1 to 45 individuals (mean 10.7).

Kopij G, Paxton M 2019. Waterbirds in the panhandle of the Okavango Delta: dry season counts over two seven-year periods. Zoology and Ecology (29) 15-27

We counted waterbirds along a fixed route in the panhandle of the Okavango River in Mahango Game Reserve in the dry season during two seven-year periods (1991–1997 and 2000–2006). Palearctic migrants represented by 11 species in 1991–1997 and nine species in 2000–2006 together composed only a small percentage of all birds recorded in both periods. The two most numerous foraging guilds were birds foraging in shallow water and those foraging in deep water. The former guild was more numerous in 2000–2006, while the latter guild was more numerous in 1991–1997.

Richmond-Coggan L 2019. The Namibian leopard: National census and sustainable hunting practices.

The African Leopard (Panthera pardus pardus) is one of Africa's most distinguishable big cats. As the leopard has such a broad geographical range combined with its cryptic activities there is a limited amount of empirical evidence that exists which in turn can be applied to adaptive management strategies, through practical conservation methods and monitoring across Namibia and Southern Africa.

Craig GC, Gibson DSC 2019. Aerial survey of north-east Namibia - Elephants and other wildlife in Khaudum National Park and neighbouring areas, September 2019.

An aerial survey of wildlife and domestic livestock took place in the Khaudum National Park and its neighbouring areas from 18th to 23th September 2019 as part of a wider survey including Zambezi Region. A total area of 14029 km2 was sampled at intensities from 5% to 20%. The estimated numbers of numbers of each species are given in the table below. The increase in estimated numbers of elephants since 2013 has been greater than expected from natural reproduction, but the overall trend from 1998 shows an average rate of increase of 4.4% per annum.

Craig GC, Gibson DSC 2019. Aerial survey of north-east Namibia - Elephants and other wildlife in Zambezi Region, September/October 2019.

An aerial survey of wildlife and domestic livestock took place in Zambezi Region from 25 th September to 4 th October 2019 as part of a wider survey including Khaudum National Park and its neighbouring conservancies. A total area of 17 380km2 was sampled at intensities between 10 and 40%. The estimates of numbers of each species are tabulated below. The estimated number of elephants is lower than that from the 2015 survey, but the change is not statistically significant. There were considerably fewer elephant carcasses seen in 2019.

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.

Amutenya KL 2019. Khaudum National Park's full moon waterhole game count, October 2019.

The waterhole fool-moon game count survey was conducted during the hottest period of the year (October) for a duration of 72 hours (3 days and 3 nights), which ensured that wildlife in the park is solely dependent on artificial water points. The survey was conducted at all the 13 water points (11 artificial and 2 fountains), with each water point having a team of eight people, working in shifts. The counting commenced on 12 October 2019, a day before the full moon and finished on 15 October 2019, a day after the full moon.

Augustine BC, Royle A, Murphy SM, Chandler RB, Cox JJ, Kelly MJ 2019. Spatial capture-recapture for categorically marked populations with an application to genetic capture-recapture. Ecosphere 10 (4) e02627

Recently introduced unmarked spatial capture–recapture (SCR), spatial mark–resight (SMR), and 2-flank spatial partial identity models (SPIMs) extend the domain of SCR to populations or observation systems that do not always allow for individual identity to be determined with certainty. For example, some species do not have natural marks that can reliably produce individual identities from photographs, and some methods of observation produce partial identity samples as is the case with remote cameras that sometimes produce single-flank photographs.

Efford MG, Boulanger J 2019. Fast evaluation of study designs for spatially explicit capture-recapture. Methods in Ecology and Evolution 2019
  1. Spatially explicit capture–recapture methods use data from the detection of marked animals at known points in space to estimate animal population density without bias from edge effects. Detection is by means of stationary devices such as traps, automatic cameras or DNA hair snags. Data collection is often expensive, and it is not obvious how to optimize the frequency of sampling and the spatial layout of detectors.
Craig GC, Gibson DSC 2019. Aerial survey of north-eastern Namibia - Elephants and other wildlife in Khaudum National Park and neighbouring areas, September 2019.

The 2019 aerial survey of wildlife in Khaudum National Park and Neighbouring Areas, Namibia, was commissioned by KfW on behalf of the Directorate of Scientific Services, Ministry of Environment and Tourism (MET), Government of Namibia as part of the survey of elephants in north-eastern Namibia.

The estimated number of elephants is lower than that from the 2015 survey, but the change is not statistically significant.  There were considerably fewer elephant carcasses seen in 2019. However as a result of the policy of MET to remove carcasses from the field, mortality can no longer be estimated from the aerial survey results. Illegal hunting of elephants continues to take place in the area.
Namibian Chamber of Environment (NCE) 2019. Gaining insights into the secret lives of wild animals. Conservation and the Environment in Namibia (2019)

If you have had the privilege of spending plenty of time watching wildlife in Africa's wilderness areas, it is likely that you have spotted an animal wearing a collar. In the context of a safari in the wilderness the presence of a clunky leather collar around the neck of a majestic lion or elephant may seem out of place and even jarring, as it reminds us that man's impact on the environment extends right into the lives of individual animals. This may leave you wondering: why are collars necessary? What benefit do the animals get from humans catching and collaring them?

Kolberg H 2012. Report on the Winter 2011 Wetland Bird Counts in Namibia . Lanioturdus 45 (1) 31-40

The winter wetland bird counts were conducted during July and August 2011 at 32 sites throughout Namibia. The abnormal rainy season experienced in most parts of the country had resulted in plenty of water still being in the field and this was evident in the counts. Lower numbers than usual were recorded at most sites and the Walvis Bay count was the lowest since regular counts were started. The low numbers are due to an almost complete absence of flamingos, lower than usual numbers of geese and ducks and the absence of certain waders e.g.

Kolberg H 2012. Summary of the 2012 Summer Wetland Bird Counts in Namibia . Lanioturdus 45 (4) 21

Wetland bird counts were once again conducted throughout Namibia during the months of January and February 2012. A total of 33 sites were covered resulting in 262 833 birds of 112 species. For the first time since 2007 counts were also conducted in the Caprivi, on the Okavango and the Kwando Rivers. The effects of the good rainy seasons over the past few years are still very evident with low numbers of especially flamingos and ducks recorded at the coast.

In 2011, the Ministry of Environment and Tourism conducted a questionnaire to various stakeholders to determine relative abundance of large carnivores throughout Namibia. The results of this questionnaire were quantified and mapped to establish the current range and relative abundance of the six Namibian large carnivores. Recent population estimates for leopards are used here, however, the remaining species we used estimates from the previous Atlas as our best estimates to date.

Conducting aerial surveys is one of the core functions of the Ministry of Environment and Tourism. The surveys are essential management tools, allowing for informed decision making. Aerial surveys have been conducted in Etosha National Park since 1968. Apart from a series of elephant surveys, these surveys were strictly speaking not comparable as they were undertaken at irregular intervals with different sampling intensities and area cover. The first comprehensive multi-species sample count was conducted in 1995, and repeated in 1998, 2000, 2002, 2004, 2005 and 2010.

This report provides feedback and results of the annual game count held on NamibRand Nature Reserve and the Pro-Namib Conservancy on 2 June 2012 - for the eighth consecutive year since the counts were initiated in 2005. As usual, this event was combined with the Reserve’s annual general meeting, which makes it an ideal opportunity to hold a game count with community participation. In June 2009 a new area was added to the existing eight zones (Zone 9), in order to incorporate the Pro-Namib Conservancy.
