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 and 2020, the number of waterholes was increased to 26 covering 10 conservancies. Counts were undertaken over a period of 2, 3 or 4 days during which time all animals seen were counted.

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 Okavango River system, about 480 kms of which constitutes the border between Namibia and Angola, has previously been largely neglected in the annual wetland water-bird counts programme conducted throughout Namibia. The exceptions have been the Mahango Game Reserve and a section of the river at Shamvura Camp where voluntary wetland water-bird counts have however been conducted over a consecutive period of 15 years and 11 years respectively. The remainder of the river had been left uncounted until 2012.

The following is a summary of waterbird count data for selected species in Namibia, covering the period 1977 to December 2008.

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.

An aerial survey of wildlife and domestic livestock took place in the Khaudum National Park and surrounding conservancies from 17th to the 22nd September 2013. A total area of 15200 km2 was sampled at an average intensity of 7.1%.

Mountain Zebra numbers were up in 2013 due to movement into the park from the west to take advantage of the artificial waters and better grazing.

This report provides summarised results and analysis of the annual game count held on the NamibRand Nature Reserve and Pro-Namib Conservancy on the 1st of June 2013- for the ninth consecutive year since the count was initiated in 2005. This was also the second year running that the farms Springbokvlakte and Saffier were included in the count since they joined to the reserve in 2012. Teamwork was once again the essence of the day as all concessionaires, landowners, neighbours and NRNR staff joined in to participate in the event.

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.
