Estimate from John Hart obtained in 2009. Details: 5447 km2 were surveyed using 90 one-kilometre line transects.
Effort was 161 km
There were 122 dungpiles
Encounter rate was 0.75 (95% cl 0.5-1.14)
ESW was 2.18m
Dung density was 173 (95% cl 111-270)
Elephant density was 0.10 (95% cl 0.064-0.16) giving 551 elephants (95% c.l. 353-860) if 19 and 90 are used as multipliers for deposition & decay rate, respectively
