阿根廷伊贝拉湿地美洲豹重引入记
In the vast, waterlogged expanse of northeastern Argentina, the Iberá Wetlands have long been a sanctuary for capybaras, marsh deer, and caimans. Yet for decades, the top predator that once shaped this ecosystem—the jaguar—remained absent, extirpated by hunting and habitat loss as early as the mid-20th century. Then, in 2021, came an audacious experiment: the reintroduction of the jaguar into its ancestral home, a project spearheaded by a conservation foundation that aims not merely to restore a species but to reanimate an entire ecological dynamic.
The process is anything but straightforward. Captive-born jaguars, raised in semi-wild enclosures at the Iberá National Park, undergo what biologists call a 'de-domestication' protocol—minimising human contact, teaching them to hunt live prey, and conditioning them to the threats of a world they have never known. One early reintroduced male, Jatobá, a six-year-old born in a breeding centre, spent months wearing a GPS collar that tracked every cautious prowl through the marsh grass. The first kills were clumsy; a caiman proved too hardy a challenge. But gradually, instinct reasserted itself, and Jatobá now roams a territory of over 40 square kilometres.
