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.

Craig GC, Gibson DSC, Uiseb KH 2021. Namibia's elephants - population, distribution and trends. Pachyderm 62 35-52

Namibia's elephants extend across the north of the country. They occur in six main areas of the known Namibian range - the north-west, Etosha National Park (NP), Mangetti National Park, northern Kavango, Khaudum National Park/Nyae Nyae Conservancy and Zambezi Region. Seasonal changes in distribution are related to water availability. There are movements of elephants between Namibia and its neighbours, particularly Botswana, and mainly from Zambezi Region. The largest populations are found in the north-east of the country, in Khaudum/Nyae Nyae and Zambezi Region.

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.

Craig GC, Gibson DSC 2019. Aerial survey of north-eastern Namibia: Elephant and other wildlife in Zambezi Region, September/October 2019. An aerial survey of wildlife and domestic livestock took place in Zambezi Region from 25th September to 4th 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. 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.

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.

Kolberg H 2017. Status assessment of Namibia's vultures . Lanioturdus 50 (1) 9-17

Vultures provide essential ecological services, yet are amongst the world's most threatened species with populations having declined by more than 95% within ten years in some places. The biggest factor causing this decline is the use of poison, either intentionally or unintentionally. Other factors causing declines are collision with and electrocution by powerlines, illegal harvesting for traditional medicines, habitat loss and drowning in reservoirs.

Craig GC, Gibson DSC 2016. Aerial survey of elephants and other animals in north western Namibia, September/October 2016.

An aerial survey of elephants and other animals was conducted in North West Namibia from 16th September to 8 th October 2016. A total area of 63431km2 was sampled at an average intensity of 8.19% using both transects (at an average of 6.7% sample intensity) and block counts (9.88% sample intensity). Total counts were conducted additionally by flying 921.5km along six rivers.

The species accounts are very detailed, doubtlessly benefitting from Peter's intimate and long-term knowledge of Botswana's birds. The range maps give one an immediate indication of where the bird occurs and the breeding bars give one an idea of when to expect the bird and when it breeds. These will prove handy when identifying e.g. migratory birds. The excellent illustrations show the birds in their local race and where sexes and ages differ, these are also illustrated. Perhaps one shortcoming of the illustrations is, that diagnostic features e.g.

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…

Gondwana Collection Namibia 2015. Gondwana Canon Park game count 2015.

Numbers of most species dropped during 2015 due to the effects of the drought & the lack of grazing. Although there were a few mortalities, many animals have moved to areas outside the park where conditions are more favourable. This is to be expected in an open system.

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).

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.

Craig GC, Gibson DSC 2014. Aerial survey of elephants and other wildlife in Zambezi Region September/October 2014.

The 2014 aerial survey of wildlife in Zambezi Region (formerly Caprivi Region) was conducted between 25 September and 4 October 2014. While the main emphasis was on numbers and distributions of elephants and elephant carcasses, sightings of other species were recorded as well as sightings of illegal activities and human settlements. The survey was conducted according to standard practices using stratified systematic transect sampling (Norton Griffiths, 1978) in a light aircraft (a Cessna 182) flying at a nominal height of 300 feet above the ground.

Kolberg H 2013. Report on a mountain zebra aerial survey in the Naukluft and Khomas Hochland, 19 to 24 June 2013.

An aerial survey specifically aimed at mountain zebra (Equus zebra hartmannae) was carried out by the survey unit of the Ministry of Environment and Tourism from 19 to 24 June 2013. The survey covered the Naukluft Mountains in the Namib-Naukluft Park and a large area of the Khomas Hochland west of Windhoek, between the Swakop River in the north and the Naukluft Mountains in the south (Figure 1). The survey was carried out using a Bell Jet Ranger 206 helicopter (V5-HIR) with a crew of four using standard aerial survey methodology.

Craig GC, Gibson DSC 2013. Aerial survey of elephants and other wildlife in the Caprivi May/June 2013.

An aerial survey of wildlife and domestic livestock took place in the Caprivi from 29 May to 8 June 2013. A total area of 16733 km2 was sampled at an average intensity of 12.7%. The estimates of numbers of each species (with their 95% confidence range) are given in the table below. The population of elephants has increased at an average rate of between 1.4% and 8.3%.per annum. However, the ratio of carcasses to live elephants indicates a possibly unsustainable number of animals being killed in much of the Caprivi.

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.

Kolberg H 2012. Report on an Aerial Survey of Etosha National Park, 6 to 17 August 2012.

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.

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.

Namibia was blessed with extraordinary rains in most parts of the country early in 2011 and this is evident in the results of the summer wetland bird counts. Access to many of the count sites was difficult due to the wet conditions. In fact, the count at Lake Oponono had to be abandoned because of the muddy conditions. Rain interrupted many counts and even at Sandwich Harbour the counters had to endure about two hours of pouring rain before continuing with the count. Oddly enough, Tsutsab Vlei, near Tsintsabis in northern Namibia, was bone dry when the counts were done.
