Ten lions have been found dead in the Ngorongoro Conservation Area in northern Tanzania, with reserve authorities suspecting poisoning as the cause of death. The Ngorongoro Conservation Area Authority (NCAA) announced that the animals were discovered on September 18 in the Ndutu area of the reserve, and has launched an investigation both to confirm the cause of death and to identify those responsible.

The Ngorongoro Conservation Area is one of Africa's most celebrated wildlife destinations, built around the world's largest intact volcanic caldera — a collapsed crater stretching 17 to 21 kilometres in diameter. The reserve, a UNESCO World Heritage Site, is home to a wide range of endangered species and draws visitors from around the world. It encompasses highlands, savannahs and forests across a vast area of Tanzania.

The deaths come amid long-running and increasingly tense disputes between the Tanzanian government and the Maasai, the semi-nomadic community that has traditionally lived within the conservation area. The government has argued that population growth in the region — which has surged from around 8,000 residents in 1959 to more than 100,000 today — is damaging wildlife habitats. Since 2022, an eviction programme has been enforced, leading to repeated and sometimes deadly confrontations. Last month, a United Nations committee urged Tanzania to immediately halt the forced displacement of Maasai communities in both the Ngorongoro and Loliondo areas.

The suspected poisoning of the lions is part of a broader pattern of wildlife deaths in the region. At least 20 elephants have died since June in Kenya's Amboseli ecosystem, near the border with Tanzania, in what is believed to have been poisoning with pesticides, though whether that was deliberate or accidental remains unclear. Earlier this year, fifteen elephants also died near the Kenya-Tanzania border under similar suspicious circumstances.

Conservationists warn that the recurring poisonings highlight the urgent need to address the conflict between wildlife conservation policies and the rights and livelihoods of local communities. When people are forcibly removed from ancestral lands in the name of conservation, the resulting tensions can translate into direct threats to the very wildlife those policies are meant to protect.
