GRUMETI, Tanzania—In Tanzania’s Grumeti Game Reserve, next to Serengeti National Park, elephants roam, rangers sleep more peacefully at night, and poachers have been put on notice, thanks to new technology designed to protect one of the world’s most endangered species.
In response to the surge in ivory poaching in Africa, where the elephant population fell by around 20 percent between 2006 and 2015, U.S. philanthropist and Microsoft co-founder Paul Allen and technologists from his company Vulcan Inc. have developed EarthRanger.
