Since the reintroduction of jaguars in 2021, Argentina has witnessed a remarkable revival of this apex predator, long absent from its natural habitat due to local extinction. What began with fewer than ten jaguars released into the Iberá Park has blossomed into a thriving population exceeding 50 individuals by May 2026, according to the National Parks Administration.
Located in the northeastern province of Corrientes, Iberá Park has become the centerpiece of a broader conservation and rewilding effort led by the organization Rewilding Argentina, which has been dedicated to reversing species extinction in the country since its inception in 2010. Beyond simply restoring jaguars to their historic range, the initiative has contributed meaningfully to wider biodiversity restoration and the revitalization of local economies.
Origins and Expansion of the Jaguar Reintroduction
The roots of this ambitious project stretch back to 1997, when conservationists Douglas and Kristine Thompkins were invited to explore the Iberá wetlands for potential environmental support. While Kristine found the conditions challenging, Douglas developed a deep appreciation for the area’s ecological significance. Within a month of their visit, Douglas’s Conservation Land Trust acquired the San Alonso Ranch, a 28,170-acre island situated in the heart of the wetlands, setting the stage for future conservation work.
Building on this foundation, Rewilding Argentina initiated the jaguar reintroduction in 2021, releasing a small group comprising mothers with four cubs and an additional female. This careful release has since resulted in a burgeoning jaguar population that now roams freely throughout Iberá Park. Furthermore, some jaguars from this population have been relocated to El Impenetrable National Park in Chaco Province, extending the species’ restored range within Argentina.
These majestic predators, often viewed with apprehension, have proven to be invaluable allies in habitat restoration. Their presence not only strengthens the ecosystem’s balance but also supports eco-tourism and related economic activities in the region, underscoring the multifaceted benefits of successful rewilding efforts.
