This dataset comprises aerial sample count data from a survey conducted in the Zambezi Valley, Zimbabwe, during August 2014. The survey was conducted using a Cessna 206, giving an estimated elephant population of 11 656 based on a coverage of 12.6% of the survey area of 17 003 km². This population estimate represents a 40% decline in elephant numbers since the previous survey in 2001. The all-carcass ratio was observed to be 5.8%. If it is assumed that all unidentified carcasses were in fact elephant carcasses, then the all-carcass ratio increases to 6.1%.
