Listening and watching: do camera traps or acoustic sensors more efficiently detect wild chimpanzees in an open habitat?

Anne-Sophie Crunchant, David Borchers, Hjalmar Kuehl & Alex K. Piel
1. With one million animal species at risk of extinction, there is an urgent need to regularly monitor threatened species. However, in practice this is challenging, especially with wide-ranging, elusive and cryptic species or those that occur at low density. 2. Here we compare two non-invasive methods, passive acoustic monitoring (n=12) and camera trapping (n=53), to detect chimpanzees (Pan troglodytes) in a savanna-woodland mosaic habitat at the Issa Valley, Tanzania. With occupancy modelling we evaluate...
