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.

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.

The Okavango River in Namibia, from the Angolan border just northwest of 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 whole Mamili National Park; and the Zambezi River for its entire length on Namibia's border, including parts of the adjacent East Caprivi floodplains, were survey from the air in September 2007.

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.

Conducting aerial surveys is one of the core functions of the Ministry of Environment and Tourism. The surveys are essential management tools, allowing for informed decision making. Aerial surveys have been conducted in Etosha National Park since 1968. Apart from a series of elephant surveys, these surveys were strictly speaking not comparable as they were undertaken at irregular intervals with different sampling intensities and area cover. The first comprehensive multi-species sample count was conducted in 1995, and repeated in 1998, 2000, 2002 and 2004.

Namibia's loyal wetland bird counters once again delivered the goods in July/August in the twice annual wetland bird counts. In total 141704 birds of 112 species were counted at 21 localities.

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.

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.

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.

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.

Aerial surveys have been conducted in Etosha National Park since 1968. These counts were strictly not comparable as they were undertaken at irregular intervals with different coverage, The first comprehensive sample count was done 1995, Since then sample counts were completed in 1998 and 2002. The 2002 survey is therefore the fourth complete sample count of Etosha. The objectives of the 2002 survey were as follows: 1. To provide comparable estimates and trend data for the most important species surveyed in support of speies management plan. 2.

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).

Etosha National Park has a long history of aerial game counts, the first experimental counts being conducted in the late 1960's. Only in the late 1980's were systematic sample counts introduced. A big advance in the actual procedure and analysis was made with the introduction of GPS and GIS software used since 1995. The 2000 census is the third census flown based on GPS transects and were GPS waypoints were recorded for sightings made.

Etosha National Park, hereafter referred to as Etosha, was counted as part of the first co-ordinated regional Elesmap census from 15 July to 3 August 1995. The aim of this report is to present the results of the elephant count, data for the other species will be presented separately. Etosha is a 23 000 km² conservation area surrounding a large saline pan. The vegetation is mainly open Mopane and Acacia savanna and short grass plains. Topography is mainly very flat, with only a few hills in the west. For a detailed description see inter alia le Roux et al.(1988).
