Poster summarising the results of the 2012 north west game count.

This is the last article in a series describing the results of regular wetland bird counts in Namibia. This paper looks at eight coastal sites, including two of Namibia's four Ramsar sites i.e. Sandwich Harbour and Walvis Bay. Unfortunately data for Namibia's other coastal Ramsar site, the Orange River Mouth, is incomplete and hence it has not been included in this analysis. (Larger scale replications of the graphs in this article are attached to the end of this edition).

The objective of this survey was to obtain a national estimate for elephants in Namibia. Fieldwork took place between 29 July and 11 August 2011 (Etosha and Tsumkwe), 6 to 10 September 2011 (Caprivi) and 19 to 25 November 2011 (Northwest Namibia). Areas covered are shown in Figs 1-3. The survey was a sample count at a variety of sampling intensities, depending on assumed elephant densities, in order to obtain a reasonably precise estimate with minimal effort. NW Namibia was a block-sample count flown by helicopter (with some areas of known high occupancy being total-counted).

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.

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.

Poster summarising game count results for 5 conservancies in the south of Namibia in 2009, with trends for 2005 - 2009.

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.

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…

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).

Protected and proclaimed areas in the Caprivi, Namibia, hold most of the economically valuable wildlife species in that region. This wildlife is presently being viewed as a potential resource base to support the many community-based conservation and development programmes in the Caprivi.

Aerial Survey of Bushmanland 9-17 June 1980.

Modern works on the distribution of Ungulate Mammals in South West Africa are those of Wilhelm (1931), Shortridge (1934) and Bigalke (1958). Older accounts are those of Fischer (1914) and that published by the German Colonial Office in 1913. The purpose of the present study has been to determine the distribution and approximate sizes of the populations of Kudu, Gemsbok, Springbok, Eland, Hartebeest and Hartmann's Mountain Zebra primarily in the farming areas of the Territory, but including also the distribution in the Bantu Reserves within the border of the Police Zone (Fig. 1…

The aerial survey includes the Eastern Floodplain area from the Zambian border to the Nkasa Rupara National Park border. This represents 1042 square kilometer area stretching over a 380-km portion of the Zambesi , Chobe and Linyanti Rivers. The area is surveyed during north-east wetland counts by fixed- ing aerial surveys and hel icopter surveys. Hel icopter surveys use two observers, one data recorder and a pilot.

The aerial survey includes the Kwando River from the Angola border to the Botswana border.

This poster presents the results of aerial surveys of game animals in the wetlands of north-eastern Namibia. The area is surrounded by Angola, Botswana, Zambia and Zimbabwe and is a key area for wildlife, which moves freely between Namibia and neighbouring countries. The aerial surveys cover the Okavango, Kwando, Linyanti , Chobe and Zambezi Rivers and their associated wetlands and floodplains. The Okavango, Kwando, Linyanti and Zambezi rivers provide perennial water.
