Jaguars, a Keystone Species, Reintroduced to the Iberá Wetlands 🏝️🐆🌍
In a hot and vibrant landscape filled with the mysterious sounds of the wild, Jaguars have made a triumphant return to the Iberá wetlands in Argentina's Corrientes province after an absence of 70 years. The ambitious effort to reintroduce Jaguars to this region is a decade-long collaboration between Rewilding Argentina and Tompkins Conservation.
On January 7, 2021, a mother Jaguar named Mariua led her family of three, including her cubs Karai and Porã, through an open gate into the vast 1.7 million acres of protected wilderness that constitute Iberá National Park. Equipped with a GPS collar, Mariua's movements are tracked by the team at the Jaguar Reintroduction Center, led by Sebastián Di Martino, the conservation director at Rewilding Argentina.
The Iberá wetlands, characterized by marshes, lakes, lagoons, and watercourses, now serve as the home for Jaguars, marking a crucial milestone in the rewilding project. The strategy involves anchoring a genetically diverse population of Jaguars to Iberá, aiming to restore ecological balance, preserve local culture, and boost the economy.
With the jaguar absent for decades, there is an overabundance of prey animals in the Iberá wetlands, providing sustenance for Mariua and her cubs. The reintroduction of at least six more Jaguars in the coming year is expected to contribute to restoring the natural balance of the ecosystem.
Kristine Tompkins, president of Tompkins Conservation and UN Patron of Protected Areas, emphasizes the importance of not only protecting but also restoring and rebuilding ecosystems. The rewilding initiative addresses the drastic loss of the Jaguar's original habitat, with 40% lost globally, leading to its extinction in Uruguay and El Salvador and the classification of the species as Critically Endangered in Argentina.
Reintroducing Jaguars, considered a keystone species and apex predator, has cascading effects on the ecosystem. Their presence regulates herbivore populations, eases pressure on vegetation, reduces soil erosion, and helps control the spread of disease.
Sebastián Di Martino notes the critical ecological role top predators play in maintaining ecosystem health. The absence of these predators can lead to degradation and, in extreme cases, ecosystem collapse. In Iberá, hunting and habitat loss were the main drivers of the jaguar's extinction.
Beyond ecological benefits, the Jaguar's return offers economic opportunities for local communities through ecotourism initiatives. The intimate knowledge locals possess about the land positions them as leaders in guiding visitors across Iberá. The project also instills a sense of pride and belonging among the people of Corrientes, with Senator Sergio Flinta expressing appreciation for the initiative.
The rewilding of Jaguars in the Iberá wetlands has been met with enthusiasm rather than resistance, surprising the conservationists. Kristine Tompkins emphasizes the unusual and heartening support from the people of Corrientes, who see the return of Jaguars as a source of pride. The project has even inspired school kids to paint their faces with jaguars, symbolizing a collective commitment to the success of this extraordinary rewilding effort.
