The Ongava Research Centre is collecting images of cheetahs and leopards in Etosha National Park in order to provide reliable population estimates of these predators for the first time. Did you know that there is no reliable information about the number of cheetahs and leopards in the Etosha National Park? Last year, the Ongava Research Centre (ORC) therefore called on visitors to the national park to take part in a survey by sharing pictures and sightings of cheetahs and leopards.

So, how many elephants is too many elephants? It's a question people have wrestled with for ages. Kruger National Park, home to one of Africa's largest elephant populations, has seen their numbers grow from just a handful in the early 1900s to over 31,000 by 2020. That's a lot of elephants! A recent study using smarter aerial surveys and fancy math gives us a more clear picture of just how fast these gentle giants are multiplying. Turns out, since 2013, their numbers have been growing by about 5.3% each year.

In 2022, an aerial survey for African savanna elephants (Loxodonta africana) was conducted over the Kavango-Zambezi Transfrontier Conservation Area (KAZA) in southern Africa. KAZA is a 520,000-km² network of protected areas in Angola, Botswana, Namibia, Zambia, and Zimbabwe. The aerial survey found that KAZA holds ~228,000 elephants, confirming that this is the world’s largest population of savanna elephants and a critical stronghold for this endangered species.

New research comparing data from the two largest-ever elephant surveys reveals the overall population in the Kavango Zambezi Transfrontier Conservation Area is stable, but also uncovers some concerning local trends. Elephant numbers in Botswana, home to more elephants than any other country, are stable overall, but declining numbers in areas where hunting is permitted, and increasing numbers in protected areas, suggest underlying issues for Botswana's elephants.

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, the populations of many species have since shown a steady decline.

Four species of otter (Carnivora: Mustelidae) occur in Africa, of which the African clawless otter (Aonyx capensis) and spotted-necked otter (Hydrictis maculicollis) are known to occur in Namibia, although very little is known about their biology and distribution. Both species are listed as Near Threatened by the IUCN Red List of Threatened Species because of a reported decline in their numbers.

The desert-adapted lions (Panthera leo) of northwest Namibia inhabit arid and semi-arid habitats, primarily within communal conservancy lands, which they share with semi-nomadic pastoralists. Though of considerable conservation interest, no systematic population survey of these lions has previously been attempted. From 6 November 2022 to 6 January 2023, 45 trained surveyors covered approximately 40,000 km² of conservancy and government-managed lands, identifying individual lions by vibrissae (whisker-spot) patterns and other demographic indicators.

Waterhole counts were undertaken at selected sites in the escarpment zone of north-west Namibia. In 2018,18 waterholes in 7 conservancies were counted but from 2019 onwards, the number of waterholes was increased to more than 25 covering 11 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.

conservancy and 2 in Muduva Nyangana. Counts were undertaken over a period of 2 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. Waterhole counts are therefore best suited to species (like elephants) which need to make regular trips to water points. Estimates are calculated using the number of count days, and the drinking frequency of the species.

Estimates were calculated using DISTANCE. Most transects were foot counts, although some vehicle transects were also counted (5 in Mahango and 3 each in Buffalo and Kwando). While foot transects conform to an evenly spaced regular grid system, vehicle transects follow park roads and are prone to sampling and habitat bias due to the oversampling of boundary tracks and river sections. Consequently, the estimates presented below were derived from analyses restricted to foot transects only.

Estimates were calculated for 2024 using DISTANCE. Due to low numbers of sightings, in most cases, at least the last 5 years of data were used in analyses to generate detection profiles for each species. Only foot transects were used in analyses for Mudumu N.P. Some contiguous conservancies have been grouped in which case estimates are provided for the combined area.

Game counts in Luengue-Luiana N.P. (proclaimed in 2011) were initiated in 2018. Three road section transect routes were initially established. A further two were added in 2021. The transects are limited to the extreme south-eastern portion of the park and represent an area of approximately 2,030 km² . The vegetation of the park is dominated by broadleafed savannah with several riparian networks crossing the park. In total 29 species have been recorded. For large herd species like buffalo, or floodplain species like red lechwe linear density provides the best measure of animal…

Line transects were initiated 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 27 species including 7 predator species. Based on average spoor sightings and Event Book records, hyaena are the most common predator, followed by wild dog, leopard and jackal. The top 3 species in terms of sightings between 2017 and 2024 included wildebeest, elephant and kudu.

The fundamental purpose of game counts in communal areas is to inform conservancies and MEFT of wildlife trends for the purposes of adaptive management of resources. While estimates of species numbers are provided, these should only be considered as an approximate guide to species abundance. In 2024: populations of the main game species showed positive or stable trends and numbers of gemsbok and kudu were at more typical levels compared with 2023. The only species showing a downward trend was steenbok. Elephant numbers were similar over the past 3 counts.

Boat counts were undertaken along the Kwando River from the Angolan border to the southern boundary of Mudumu National Park (2021, 2022, 2023, 2024) and along the Okavango River from the northern part of the Buffalo core area to the Botswana border (2023, 2024). Total river length counted is approximately 190 km. Within Namibia, animals on each side of the river were counted while, in the case of hippo, animals in the river were also counted.

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…

The survey took two hours 54 minutes, which translates into a search rate of 1.6 km/min. The flight path was recorded on the GPS tracklog and is shown in Figure 2 (deviations from the transects are where rhino, elephant or large herds of animals were encountered). A total of 253 sightings were recorded during this time (Figure 3) which comprised 1539 animals of seventeen species (Table 1). Kaross game camp is 144 km² in size so the density of animals calculates to 10.7 animals/km². The distribution and herd size for selected species is shown in Figure 4 to Figure 11.

This proposed study focuses on the elephants of the Kunene/Etosha cluster. The elephants outside Etosha is still largely a free ranging population over much of a 100 000 km² range. For the purpose of this proposal the study area (Figure 1) encompasses the extreme western area of Etosha, Skeleton Coast Park, communal conservancies, concessions and the private farming land south of Etosha. The average rainfall ranges from <50mm to 300mm. Recently, human-elephant conflicts have received a lot of attention in this Region.
