When Edward Ndiritu joined Lewa Wildlife Conservancy, central Kenya, as a rhino monitor in 1996, poaching had already reduced the nation's black rhino population from 20,000 in 1970 to fewer than 300. Driven by a fear that they might disappear completely, Edward worked his way up the ranks to become the head of Lewa's anti-poaching unit. In 2015, his team’s community-minded approach to conservation won him the first Wildlife Ranger Award from conservation charity Tusk. While a rhino hasn't been killed by poachers in Lewa since 2020, the threat endures.
