Population Survey

The 2011 Wonga-Wongue Reserve estimated elephants using the dung count method. Only 9 transects were walked but CV was 26%. Elephant population was (after E dung had been removed) 1039 (95% c.l. 601-1797). The dung decay rate was not done on site but it was taken to be 81.82 days using 14 reviewed studies.
