This archive of reports of wildlife surveys in Namibia aims to:
Public access to information is a vital component of ensuring community engagement in prevalent issues. Wildlife surveys are critical to determine the health of wildlife populations and determine trends over time to guide conservation and management actions.
Wildlife surveys are done for different species using methods that are suited to counting them (e.g. by air or road) in their natural habitats. Such surveys need to be repeated over time to detect long-term trends and inform conservation managers. The Namibian government, non-governmental organisations and private reserves all conduct regular surveys covering different parts of Namibia and targeting different species. This archive will thus serve as a repository of our collective knowledge of the trends and status of a variety of species occurring throughout Namibia.

Annual counts were extended to include Ai-Ais Hot Springs in 2022. Three transects were counted representing an area of around 407 km² . More years of data are required before any trends or estimates can be generated.

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.

The dramatic spike in the proportion of gemsbok seen in Hobatere relative to the rest of the north-west reflects the decline in animal numbers in communal conservancies. In 2021, Palmwag, Etendeka and Hobatere concessions (only 9% of the total area) accounted for 60% of all gemsbok seen in the north-west. Due to the higher number of animals seen in Orupembe conservancy in 2022 this ratio dropped to 31%.

The Palmwag and Etendeka concession areas are important refuges for at least five of the main game species. The contrast in trends between kudu and gemsbok is noteworthy. While gemsbok numbers have declined dramatically throughout the entire north-west region, the contribution of the concessions has spiked in recent years. With kudu the contribution of concessions to numbers has dropped dramatically in the same period suggesting a different causal mechanism for the decline in numbers of the two species.

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, a subsequent prolonged dry phase has resulted in a steady decline in populations of many game species. It is unclear how much illegal harvesting has contributed to this decline.

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 25 species including 6 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 2022 included wildebeest, elephant and kudu.

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, 2020 and 2021, the number of waterholes was increased to around 26 covering 10 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.

Estimates were calculated for the current year using DISTANCE. In most cases at least the last 5 years of data were used in analysis to generate a detection profile for each species. Several conservancies have been grouped due to the low numbers of animals recorded. The bottom row of the table (hyphenated) numbers = 95% Confidence Intervals. In Sikunga, very few sightings have ever been recorded (60 for all species since 2011) and no sensible estimates for any species can be derived for this area.

Since 2021 a boat transect has been undertaken along the Kwando river from the Angola border to the southern boundary of Mudumu National Park. The total transect length is 152 km. For each species, animals on each side of the river (and in the case of hippo, in the river,) are 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.

Trends in Namibian Waterbird Populations 2_Grebes and Pelicans.pdf | 427.67 KB |
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.
