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.

Full moon waterhole counts in northern Kunene 2024.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.
Namibian Association of CBNRM Support Organisations (NACSO) 2024. Game Counts: Kavango East - July 2024.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.

Namibian Association of CBNRM Support Organisations (NACSO) 2024. Game counts Nyae Nyae Conservancy: Line transects - July 2024.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.
Namibian Association of CBNRM Support Organisations (NACSO) 2024. Game counts in north-west Namibia: Regional Summary - May 2024.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.
Namibian Association of CBNRM Support Organisations (NACSO) 2024. Game counts in Luengue-Luiana N.P. - October 2024.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…

Namibian Association of CBNRM Support Organisations (NACSO) 2024. Game counts in Bwabwata N.P. - August 2024.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.

Namibian Association of CBNRM Support Organisations (NACSO) 2023. Game counts in Sioma-Ngwezi N.P.: October 2023.Annual game counts have been undertaken in Sioma-Ngwezi National Park since 2017 using road-route sections covering the western boundary, the southern area, and central area of the park. The vegetation of the park is dominated by miombo broad-leafed savanna but with some marshland associated with the Kwando river in the west (Sinjembela road and Mufulani road A). In 2021 several new routes were driven, however data from all except Namulilo road were discarded as they overlapped existing routes. Only a portion of Mulamba road route was counted.

Namibian Association of CBNRM Support Organisations (NACSO) 2023. Game counts in north-west Namibia, regional summary: May 2023.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 prolonged dry phase after 2013 resulted in a steady decline in populations of many game species. It is unclear how much illegal harvesting contributed to the drop in animal numbers.

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!
Kopij G, Paxton M 2019. Waterbirds in the panhandle of the Okavango Delta: dry season counts over two seven-year periods. Zoology and Ecology (29) 15-27We 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.

Mendelsohn J, Haraes L 2018. Aerial census of Cape Cormorants and Cape Fur Seals at Baía dos Tigres, Angola. Namibian Journal of Environment (2) 1-6A 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.

. Lanioturdus
50 (1) 9-17Vultures provide essential ecological services, yet are amongst the world's most threatened species with populations having declined by more than 95% within ten years in some places. The biggest factor causing this decline is the use of poison, either intentionally or unintentionally. Other factors causing declines are collision with and electrocution by powerlines, illegal harvesting for traditional medicines, habitat loss and drowning in reservoirs.

The range maps give one an immediate indication of where the bird occurs and the breeding bars give one an idea of when to expect the bird and when it breeds. These will prove handy when identifying e.g. migratory birds. The excellent illustrations show the birds in their local race and where sexes and ages differ, these are also illustrated. Perhaps one shortcoming of the illustrations is, that diagnostic features e.g.

. Conservation Biology
29 (3) 877-878Many 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.

Kolberg H 2012. Report on the Winter 2011 Wetland Bird Counts in Namibia
. Lanioturdus
45 (1) 31-40The winter wetland bird counts were conducted during July and August 2011 at 32 sites throughout Namibia. The abnormal rainy season experienced in most parts of the country had resulted in plenty of water still being in the field and this was evident in the counts. Lower numbers than usual were recorded at most sites and the Walvis Bay count was the lowest since regular counts were started. The low numbers are due to an almost complete absence of flamingos, lower than usual numbers of geese and ducks and the absence of certain waders e.g.
