Text: the data for annual mortality and corresponding level of illegal killing for monitoring sites across the african elephant range including our study area is publicly availlable on the convention on international trade in endangered species (cites) website (http://www.cites.org/sites/default/files/eng/com/sc/65/inf/e-sc65-inf-01.pdf). gps positions of live and dead elephant distribution are ethically restricted as the locations may jeopardise the anti-poaching operations and thus put elephants at greater risk. the data is however available on written request from the office of senior assistant director of kenya wildlife service. the contact person is mr. patrick omondi (pomondi@kws.go.ke).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
