This dataset comprises dung count recce and line transect data from a survey conducted in the Dja Biosphere Reserve, Cameroon, in March - June 2015. The survey estimated an elephant population of 420 within the 5 260 km² survey area. This represents an 84% decline in the elephant population between 1995 and 2015, and is the first survey to have covered the whole of the Reserve. 205 x 2.5km transects were walked in a single stratum, totalling 495.3km. Dung density was recorded as 200 per km², with an encounter rate of 0.48 per km. The population estimate was modelled using parameters of dung production = 19.77 and decay rate = 90, as measured in Reserve de Santchou, Cameroon (Tchamba Martin, 1992).
