The ground survey of elephants at Lope National Park, using the dung count method. The survey took 54 days starting from late 2008 to November 2009. It was done in two stata, i.e. the North and South stratum of the Park as shown in the survey report, but could only be entered as an aggregate (the whole park) due to lack of population estimates of the North and South stratum.
