t's a grim and all too common sight for rangers at some of Africa’s nature reserves: the bullet-riddled carcass of an elephant, its tusks removed by poachers. African elephant populations have fallen by about 30% since 2006. Poaching has driven the decline. Some reserves, like Garamba in the Democratic Republic of Congo and Selous in Tanzania, have lost hundreds of elephants to poachers over the last decade. But others, like Etosha National Park in Namibia, have been targeted far less. What might explain this difference? That’s what we set out to explore in our new paper. We investigated why poaching rates vary so widely across Africa and what this might reveal about what drives, motivates and facilitates poaching. To do this, we used a statistical model to relate poaching levels from 64 African sites to various socio-economic factors. These included a country’s quality of governance and the level of human development in the area surrounding a park.
