regularly walked across the park in daytime with little harm.

Packer has documented that between 1990 and 2004, lions attacked 815 people in Tanzania, killing 563. Packer and Ikanda are among the few conservationists who believe western conservation efforts must take account of these matters not just because of ethical concerns about human life, but also for the long term success of conservation efforts and lion preservation.

It is believed to have killed and eaten at least 35 people in a series of incidents covering several villages in the Rufiji Delta coastal region. [ 106 ] Dr Rolf D. Baldus, the GTZ wildlife programme coordinator, commented that it was likely that the lion preyed on humans because it had a large abscess underneath a molar which was cracked in several places.
