The aerial sample count survey of Boma Badingilo Corridor was carried out during the late wet season i.e. late October to early November 2009. No elephants were observed in the corridor survey zone during the sampling exercise and the elephant population estimates were not derived and therefore the elephant count was submitted as an informed guess.
