The monitoring and ringing of Lappet-faced Vultures (LFV) Aegypius tracheliotos (formerly Torgos tracheliotos) in the Namib-Naukluft Park (NNP) started in 1991. Annually more areas were investigated until most of the known breeding areas were checked and the chicks ringed. The only exception is the Koigab area north of Aus, which due to the distance involved, was only surveyed once in 1998 and then from the air in 2005. At the same time areas south of Sossusvlei in the NNP and adjacent NamibRand Nature Reserve were flown. This is the longest running project of its kind in Namibia. It is providing an increasing amount of data, which can be used for wildlife management planning, by ornithologists and biodiversity researchers.
