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.

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.

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…

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).

Aerial stratified sample counts have been conducted since 1995 in Etosha. The 2015 aerial count of Etosha was conducted from 4 September till 21 September. Including the latter survey, a total of eight comparable multi-species counts have been completed since 1995.

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.

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.

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.

This is the third article in a series describing the results of regular wetland bird counts in Namibia and groups together inland sites where water is seasonally present as well as three sewage treatment plants. The article gives details for ten sites for which ten or more counts are available up to the end of 2008.

January 2010 announced its arrival with welcome and wide-spread rain throughout Namibia. The result of this was that we were expecting bumper counts at many of the inland wetlands, although the two coastal heavyweights would be expected to contribute the majority in terms of numbers, as usual. During this count cycle 26 sites were counted, an increase on previous counts, in no small part due to the efforts of the Namibia Bird Club that is now counting many wetlands around Windhoek.

This is the second article in a series describing the results of regular wetland bird counts in Namibia and groups together inland sites where water is present most of the time. The article gives details for two perennial river sites and nine dams for which ten or more counts are available up to the end of 2008.

The following is a summary of waterbird count data for selected species in Namibia, covering the period 1977 to December 2008. For each species the Red Data Book (RDB) status, both global and Namibian, is given, the population trend as per Wetlands International, the number of times the species was counted, the number of times it has passed the 1% population criterion, the maximum count and the sites where it has passed the 1% population criterion.

Data on wetland bird numbers has been collected in Namibia on an ad hoc basis since the early 1960's. Since 1991 regular counts have been conducted at several sites and thus a considerable amount of data has accumulated. This article and the ones to follow is a summary of the available data and an attempt to derive population trends for selected wetland bird populations. To date (July 2009), data from 1703 counts at 172 places has been entered into a database. A total of 177 different species of waterbird have been counted at these sites.

During the month of July 2009 volunteers once again participated in the winter wetland bird counts all over Namibia. A total of 27 wetlands were counted resulting in just over 99,000 birds of 87 species. The number of sites being counted is up thanks to the Namibia Bird Club, which is now conducting regular counts at Avis Dam, the Gammams (Windhoek) Sewage Works and Monte Christo. The Walvis Bay Ramsar site tops the list with over 50,000 birds, followed by Sandwich Harbour and the Mile 4 Saltworks.

In more than 100 countries, millions of waterbirds are counted each year. Wetlands International coordinates the International Waterbird Census (IWC) throughout the world and the data is used to e.g. designate Wetlands of International Importance and Important Bird Areas. Namibia has participated in these counts since 1990 and hence a considerable set of data has accumulated. Data is on hand for 1703 (as at July 2009) waterbird counts at 172 sites in Namibia. The earliest counts are from 1976 and a peak in terms of sites counted was reached in 1995 when 73 wetlands were counted…
