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.

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.

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.

An aerial survey of wildlife and domestic livestock took place in Zambezi Region from 25 th September to 4 th 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.

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.

The waterhole fool-moon game count survey was conducted during the hottest period of the year (October) for a duration of 72 hours (3 days and 3 nights), which ensured that wildlife in the park is solely dependent on artificial water points. The survey was conducted at all the 13 water points (11 artificial and 2 fountains), with each water point having a team of eight people, working in shifts. The counting commenced on 12 October 2019, a day before the full moon and finished on 15 October 2019, a day after the full moon.

Recently introduced unmarked spatial capture–recapture (SCR), spatial mark–resight (SMR), and 2-flank spatial partial identity models (SPIMs) extend the domain of SCR to populations or observation systems that do not always allow for individual identity to be determined with certainty. For example, some species do not have natural marks that can reliably produce individual identities from photographs, and some methods of observation produce partial identity samples as is the case with remote cameras that sometimes produce single-flank photographs.

1. Spatially explicit capture–recapture methods use data from the detection of marked animals at known points in space to estimate animal population density without bias from edge effects. Detection is by means of stationary devices such as traps, automatic cameras or DNA hair snags. Data collection is often expensive, and it is not obvious how to optimize the frequency of sampling and the spatial layout of detectors.

The 2019 aerial survey of wildlife in Khaudum National Park and Neighbouring Areas, Namibia, was commissioned by KfW on behalf of the Directorate of Scientific Services, Ministry of Environment and Tourism (MET), Government of Namibia as part of the survey of elephants in north-eastern Namibia.

If you have had the privilege of spending plenty of time watching wildlife in Africa's wilderness areas, it is likely that you have spotted an animal wearing a collar. In the context of a safari in the wilderness the presence of a clunky leather collar around the neck of a majestic lion or elephant may seem out of place and even jarring, as it reminds us that man's impact on the environment extends right into the lives of individual animals. This may leave you wondering: why are collars necessary? What benefit do the animals get from humans catching and collaring them?

Take a close look at the image above. Each black dot is a Cape Cormorant (see below) as seen from a light aircraft. Can you count the cormorants? This aerial view of a colony of Cape Cormorants is a composite of several of the thousands of images taken during a 2017 survey of Ilha dos Tigres, an island off the coast of Angola. The purpose of this survey was to document all visible animals using this island, so every dot counts!

Accurately estimating hippopotamus (Hippopotamus amphibius) numbers is difficult due to their aggressive nature, amphibious lifestyle, and habit of diving and surfacing. Traditionally, hippos are counted using aerial surveys and land/boat surveys. We compared estimates of numbers of hippos in a lagoon in the Okavango Delta, counted from land to counts from video taken from a DJI Phantom 4TM drone, testing for effectiveness at three heights (40 m, 80 m, and 120 m) and four times of day (early morning, late morning, early afternoon, and late afternoon).

The third article in the series on trends in Namibian waterbird populations summarises count data for cormorants and darter for 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.

This is the last article in a series describing the results of regular wetland bird counts in Namibia. This paper looks at eight coastal sites, including two of Namibia's four Ramsar sites i.e. Sandwich Harbour and Walvis Bay. Unfortunately data for Namibia's other coastal Ramsar site, the Orange River Mouth, is incomplete and hence it has not been included in this analysis. (Larger scale replications of the graphs in this article are attached to the end of this edition).

This article continues the series on trends in Namibian waterbird populations and summarises count data for herons and egrets for 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.

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.

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.

The objective of this survey was to obtain a national estimate for elephants in Namibia. Fieldwork took place between 29 July and 11 August 2011 (Etosha and Tsumkwe), 6 to 10 September 2011 (Caprivi) and 19 to 25 November 2011 (Northwest Namibia). Areas covered are shown in Figs 1-3. The survey was a sample count at a variety of sampling intensities, depending on assumed elephant densities, in order to obtain a reasonably precise estimate with minimal effort. NW Namibia was a block-sample count flown by helicopter (with some areas of known high occupancy being total-counted).

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.

Numbers of some species were up in 2011 due to the effect of good rains. This also caused a decrease in Mountain Zebra numbers as they moved westwards out of the park.

Areas surveyed: The Okavango River in Namibia, from just northwest the bridge on the Trans-Caprivi highway south to the Botswana border; the entire length of the Kwandu-Linyanti-Lake Liambezi-Chobe system, including the Mamili National Park; and the Zambezi river for its entire length on Namibia's border, including parts of the adjacent East Caprivi floodplains.

This study has provided baseline data on crocodile numbers from aerial and spotlight counts. These data can be used with the results of future counts to determine population trends. The census has also provided information on their distribution of crocodiles in the Kavango and Caprivi regions. And third, it has resulted in the first population estimate for crocodiles in the north-east wetlands of Namibia.

Human and, increasingly, elephant pressure on Namibia's wetlands and riparian belts are a major cause of conservation concern. Many wetland birds are listed in Namibia's Red Data Book (Simmons & Brown in prep) because of population declines caused by the degradation and destruction of wetland habitats, and because of high levels of disturbance. Good information on the status of major wetlands and their avifauna is important for their conservation management. Birds provide one of the best indicators of wetland health.

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…

An aerial wildlife survey of the Nyae Nyae Conservancy in Namibia was conducted between 27 August and 5 September 2004. Using stratified systematic transect sampling techniques the 8,900km2 area was samfled at an average intensity of 33 %, during 54 hours of flying. The survey produced population estimates with relatively narrow confidence intervals for some of the abundant species, like kudu, gemsbok and ostrich. Wildlife numbers, as a whole, appeared to have increased when compared with the previous survey in 1998. An abbreviated summary of the numbers of wildlife is listed…

The conflict between lions and pastoralists bordering Etosha National Park is a well known and documented problem. Every year lions move beyond the borders of Etosha National Park (Etosha) and prey on domestic livestock. In protection of their livestock, pastoralists shoot, trap, or poison lions. Data on these lion mortalities have been collected since 1982. Many individuals, including staff of the Ministry of Environment and Tourism, and visiting researchers, have collected these data.
