The illegal trade in wildlife is now the third largest criminal industry in the world, and men such as these Zimbabwe rangers are in the front line of the fight against it.

But unlike the organised gangs of poachers after rhino horn and ivory, rangers seldom have access to automatic weapons or proper training. Damien Mander, a former special-operations soldier in the Australian military, has set up the International Anti-poaching Foundation in response to the rhino slaughter. Here, at Victoria Falls, he leads a free workshop teaching rangers everything from weapon-use and tracking to ambush and arrest techniques.
