Dry season Aerial Survey of Gambella National Park and Surrounding areas

Gambella National Park was initially proposed in 1973, but didn’t receive official status at national or federal level until 2014. The Park was proposed primarily to protect its outstanding biodiversity and important wetland habitats, and to protect two large mammal species: the White-eared kob (Kobus kob leucotis) and the Nile lechwe (Kobus megaceros). Currently, the park hosts the largest populations of these species in Ethiopia, and also Elephant (Loxodonta africana), Giraffe (Giraffa cameleopardalis), Buffalo (Syncerus caffer), Lion (Panthera leo) and

Systematic aerial sample survey of Laikipia county, April 2016 Preliminary Report

A systematic aerial sample survey of Laikipia County (9666km2) was carried out in April 2016 by Kenya’s Directorate of Resource Survey and Remote Sensing survey teams in partnership with Laikipia Wildlife Forum and Mpala Research Centre, with funds from US AID. This report presents the preliminary results as a basis for use by management and for discussion on further analysis and application. The Laikipia upland plateau between Mount Kenya (5199m) and the Aberdare highlands (3999m) is an important area for

Long-term population dynamics of African ungulates in Waterberg Plateau National Park, Namibia

The current study was undertaken to determine long-term population trends (33 years) of ungulate species in the Waterberg National Park (WNP), Namibia, using aerial and waterhole counts of ungulates during the years 1980−2013.We tried to establish how rainfall influences the multi-species population dynamics. During this period sixteen ungulates species were recorded. Among these, eight have shown an increase in numbers during the years 1984−2013, six other decreased, and populations of two other species remained stable. Roan and sable antelope, kudu

Updated geographic range maps for giraffe, Giraffa spp., throughout sub-Saharan Africa, and implications of changing distributions for conservation

Giraffe populations have declined in abundance by almost 40% over the last three decades, and the geographic ranges of the species (previously believed to be one, now defined as four species) have been significantly reduced or altered. With substantial changes in land uses, loss of habitat, declining abundance, translocations, and data gaps, the existing geographic range maps for giraffe need to be updated. We performed a review of existing giraffe range data, including aerial and ground observations of giraffe, existing

Has the final countdown to wildlife extinction in Northern Central African Republic begun?

The wildlife populations of Northern Central African Republic experienced precipitous declines during the 1970s and 1980s. While anecdotes coming out of the region indicate that the wildlife populations remain under serious threat, little is known about their status. An aerial sample count was carried out in the Northern Central African Republic at the end of the dry season in June 2005 and covered an 85,000 km2 complex landscape containing national parks, hunting reserves and community hunting areas. Results show a

Conservation monitoring: estimating mammal densities in woodland habitats

Conservation and ecological monitoring programmes often estimate animal densities over time, but in wooded and forested areas practical techniques are still poorly developed. Here I have examined five simple methods of deriving densities of large and medium-sized mammals using line transects driven through miombo woodland habitat in Africa. These methods calculated area by dividing the number of individuals seen by (i) an average of each species’ sighting distances, (ii) a fixed 200 m belt width, (iii) the area visible from
