On safari with the wildlife poacher turned protector

I’ve never met anyone like Barichera. A spry 61-year-old, he was waiting for me on a hilltop overlooking the savannah at Singita Grumeti, a 350,000-acre private reserve in Tanzania. Working 21-day shifts from a lookout, Barichera is part of Singita’s anti-poaching unit, responsible for ensuring that animals roaming into the reserve stay safe.
