How a Mozambican park rebuilt an entire ecosystem after a devastating war

How Gorongosa National Park Brought Wildlife Back After Civil War | SLICE EARTH | FULL DOC · 52:02 · Video: SLICE Earth · Watch at the source

In short: During Mozambique's civil war, Gorongosa National Park lost 95% of its wildlife to poaching and conflict. Today, the landscape is transforming. From reintroducing predators to managing human-wildlife coexistence, discover how scientists are engineering a massive ecological rebound.

The devastation of the Mozambermican civil war (1977–1992) left Gorongosa National Park in ruins. During the conflict, elephants were hunted extensively for meat and ivory to fund the purchase of ammunition and guns. By the end of the war, the park's wildlife population had plummeted by an estimated 95%. The ecological balance was shattered; even species like the African wild dog were completely wiped out from the region.

Recovery has required a sophisticated, multi-layered approach involving both biological reintroductions and intense scientific monitoring. In 2018, a pack of 14 wild dogs from South Africa was released into the park to restore predatory pressure. Meanwhile, the elephant population has seen a robust increase, with more than 650 elephants now inhabiting the 1,500 square miles of diverse terrain, which includes mountainsides, palm savannas, and wetlands.

Modern conservation efforts, led by ecologists like Dominique Gonçalves, utilize high-tech methods to track these returning species. Using helicopters and tranquilizer darts, teams fit GPS collars on matriarchal elephant groups to monitor movement. These missions also involve gathering biological data—such as blood, saliva, and even fecal samples—to analyze diets and health. However, the park's success is tied to the 200,000 people living on its borders. True restoration involves managing human-wildlife conflict through initiatives like beehive fences and reforestation, ensuring that the rebound of lions, buffalo, and hippos is sustainable for the local communities sharing the land.
