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.

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.

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.

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.

BirdLife Botswana (the BirdLife partner in Botswana) identified and documented 12 sites as Important Bird Areas (IBAs) of Botswana. These sites are; Chobe National Park, Linyanti Swamps, Okavango Delta, Lake Ngami, Central Kalahari and Khutse Game Reserves (CKGR), Makgadikgadi Pans, Gemsbok National Park, Tswapong Hills, Mannyelanong Hill, Phakalane Sewage ponds, South Eastern Botswana and Bokaa Dam. Even though a huge amount of work has been done by BirdLife Botswana, monitoring efforts in these areas lack adequate co-ordination.

The start of the new year once again meant that Namibia's bird watchers had to dust off their binoculars and venture out to do the annual summer wetland counts. The global economic crisis does not seem to have affected the birders because I'm pleased to report that twenty-seven sites were counted although the geographic coverage is still very much biased in favour of the coast. The two Ramsar sites, Sandwich Harbour and Walvis Bay, once again came up trumps in terms of bird numbers but the most species were encountered by Wilferd at Oponono.

The southern African Lesser Flamingo population was estimated to number 55,000 - 65,000 individuals in the mid-1990s, but these were either under estimates or the numbers have increased since, because at times Kamfers Dam, the Goldfields wetlands (in South Africa), Etosha Pan (Namibia) and Sua Pan (Botswana) each support more than that number. In order to try and get to grips with the size of the southern African population of Lesser Flamingos, a coordinated survey was planned for 20-21 July 2008.

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.

Elephants occur across the entire north of Namibia with two main sub-populations in the north-east and the north-west. In 2004 the total population was estimated at over 16,000 animals and, allowing for underestimates on aerial surveys, the true number in 2007 is likely to be closer to 20,000. The north-western population is about 4,000 animals and includes the elephants in Etosha. This appears to be growing at about 3.3% per annum and expanding its range.

Namibia experienced some extreme rainfall in the first three months of 2006 and this, perhaps, is reflected in the results of the January wetland counts. One counter, Wilfred, could not get to his sites because it was too wet! In terms of numbers Walvis Bay leads by far but the Mahango yet again confirms its status as the most species rich birding destination in our country.

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.

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…

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.

Evidence of a decline in the range of elephants is provided by the survey carried out by Viljoen in 1982. The map in fig. 31 is somewhat misleading as all survey blocks in which elephants were seen are shaded even though elephants were unlikely to have been spread throughout the blocks. However, the occurrence of carcasses (cross-hatched areas) in areas where elephants are no longer found indicates a decrease in the range. Since the 1980s, the elephant counts have shown a consistent increase in the population (Fig. 32).
