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.

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).

From 2016 onwards Bamunu (2) was included in counts. In 2018 the two Protected Areas Mudumu (7) and Nkasa Ruparo (8) were not included in counts. It is important to bear this in mind when interpreting tables, charts and a time series of posters.

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.

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.

A total of 250,786 Cape Cormorants, of which 16,038 were individuals on nests in 349 colonies, and 15,831 Cape Fur Seals were counted during a complete aerial photographic census of the island of Tigres and part of the adjacent coast in Angola in March 2017. Such a concentration of birds and seals and the large number of breeding Cape Cormorants highlights the need to protect Tigres and its rich surrounding waters. Keywords: aerial census, Arctocephalus pusillus pusillus, Baía dos Tigres, Cape cormorant, Cape fur seal, Phalacrocorax capensis.

Carnivore populations face threats from increasing human populations and rapidly diminishing, suitable habitat. Large carnivores such as African lions (Panthera leo) commonly attack livestock on lands adjacent to protected areas. This can lead to human-wildlife conflict (HWC) events that result in retaliatory lion killings. Conflict is a primary driver of wild lion population declines which are estimated to have decreased by 43% in the last 20 years.

Assessing the numbers and distribution of threatened species is a central challenge in conservation, often made difficult because the species of concern are rare and elusive. For some predators, this may be compounded by their being sparsely distributed over large areas. Such is the case with the cheetah Acinonyx jubatus. The IUCN Red List process solicits comments, is democratic, transparent, widely-used, and has recently assessed the species.

After the initial and in-depth assessment of the leopard population in the Okonjima Nature Reserve via the use of remote camera traps that provided a detailed insight of their demography as well as temporal and spatial distribution patterns, a long-term monitoring program has been introduced. This aims to observe and monitor fluctuations in the composition of the population, as well as shifts and overlaps of home ranges and territories.

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.

Leopards are the most widely-distributed wild cat on earth. They are found throughout most of sub-Saharan Africa and in smaller populations within the Middle East, southwest Asia, southeast Asia and north to the Amur peninsula of the Russian Far-East. Throughout this distribution, leopards have persisted in hostile areas outside of protected areas due to their secretive nature and adaptable ability to live in a variety of habitats including sub-urban environments.

This report presents the results of the third fixed-wing aerial wildlife census of the Caprivi River systems in Namibia conducted during September 2009. The purpose of this survey is to provide recent information on the distribution, abundance and trend of wildlife species including comparisons between protected areas and conservancies. The report compares the results of this survey with earlier fixed-wing aerial surveys conducted in September 2007 and August 2004.

Knowledge of a species' ranging behaviour is both fundamental to understanding its behavioural ecology and a prerequisite to planning its management. Few data exist on the spatial ecology of cheetahs Acinonyx jubatus outside protected areas, but such areas are particularly important to their conservation. Cheetahs on Namibian farmlands occupied exceptionally large home ranges, averaging 1651km2 (
1594km2), with no detectable effect of sex, social grouping or seasonality.

Namibia is one of few African countries that support six species of large carnivore. Lions, leopards, cheetahs, spotted hyaenas, brown hyaenas and wild dogs occur primarily in the northern and western sections of Namibia. With the possible exception of lions and leopards we have a poor understanding of the exact distribution and density of these species, although available information suggests that the populations are stable. The Namibia Large Carnivore Atlas was launched to involve the tourism industry and the Namibian public in collecting baseline data on the six large…

Our present research is focussed on lions and leopards in three study sites. The Khorixas study site (10826 km2) is located in the northern Namib desert, previously known as Damaraland, and consists of an extremely arid habitat (annual rainfall 0-100mm) that stretches into the Skeleton Coast Park. This study is focussing on desert-adapted lions that frequent the Skeleton Coast Park, Torra Conservancy and the Palmwag tourism concession.

For the protection of grazing, farmers throughout for the Territory obtained permits for shooting 3, 893 zebra, 2, 025 ostriches, 172 giraffes, 183 kudus, 404 gemsbuck, 2, 513 springboks and 12 steenboks. Permits were issued for the export of 17, 724 hides to an approximate value of R 50,000. The revenue for the Administration out of levies on the export of 760 head of game by the two licensed game dealers amounted to R 2, 323. There are no levies on the export of hides. The first Administration’s policy that game should have a monetary value for the farmer, started yielding…
