Detection probabilities of ungulates in the eastern Swaziland lowveld
The management of large ungulates in Southern Africa necessitates reliable monitoring programmes to direct management action. Monitoring programmes for large ungulates typically rely on spotlight survey methods, but do not address variation in detection rates between surveys or observers. In 2009, we used a multiple observer survey technique to estimate detection probabilities for large ungulates […]
Giraffa camelopardalis, Giraffe Assessment by: Muller, Z. et al.

Nine subspecies of Giraffes are currently recognized (Dagg 2014), although some authorities dispute this taxonomic classification (e.g., Groves and Grubb 2011).

Towards understanding large mammal population declines in Africa’s protected areas: A West-Central African perspective
A raft of recent studies has highlighted a major decline in large mammal populations in many of Africa’s protected areas. A recent continent-wide assessment represented a major step forward also in terms of quantifying the decline on a regional basis, but fell short in its sampling and analysis. In this paper, a way out of […]
