The most poorly known section of the African Great Escarpment is located in Angola. It has been highlighted as a potential center of endemism for several biological groups, including herpetofauna. The region, which is critical for the conservation of Angolan biodiversity, requires urgent research. In the scope of the SASSCAL project, a herpetofauna monitoring plan is being implemented in Tundavala, in the southern Angolan escarpment. In total, 13 species of amphibians, 12 species of lizards and 9 species of snakes have been registered so far, and more are expected to occur. Among them are some important rediscoveries of Angolan endemics uncollected for decades, such as Anchieta’s treefrog (Leptopelis anchietae) and Ansorge's whip snake (Psammophis ansorgii).
