This archive of reports of wildlife surveys in Namibia aims to:
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.

NACSO Hardap and Naute Game Count 2021.pdf | 805.96 KB |
Wildlife populations in north-west Namibia were severely impacted in the 1980s by a combination of severe drought and poaching. Community conservation, formalised in 1996 through conservancies facilitated an increase in wildlife numbers through controlled utilisation and effective control of poaching. Between 1996 and 2012 most species experienced stable or growing population trends. However, a subsequent prolonged dry phase has resulted in a steady decline in populations of many game species. It is unclear how much illegal harvesting has contributed to this decline.

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.

Counts were undertaken at waterholes in the escarpment zone of north west Namibia. In 2018,18 waterholes in 7 conservancies were counted while in 2019, 2020 and 2021, the number of waterholes was increased to around 26 covering 10 conservancies. Counts were undertaken over a period of 2, 3 or 4 days during which time all animals seen were counted. Game species differ in the frequency with which they need to visit water resources with some able to acquire much of their hydration needs through foraging.

Line transects were started in 2017 and represent almost half of the total area of the conservancy and include most of the waterholes. The area not covered by transects has low animal densities due to reduced habitat suitability and people pressure. Transect counts have recorded 23 species including 6 predator species. Based on average spoor sightings hyaena are the most common predator, followed by leopard and wild dog.

Numbers of elephants counted by Nad Brain and NamPol observers between 16 -31 Dec 2021 as part of antipoaching surveillance work. The unstructered aerial search counts focussed on the river systems and were done from the Westair / NCE Cessna 182 V5 –IIM flying out of Palmwag airfield and using SRT's base camp Ma – I – Go. It was not possible to record demographics of the herds, but did count bulls individually. The bulls are in addition to the herd numbers.

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.

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).

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.

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.

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.

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.

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).

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.

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.
