If the jaguar returns, everything else can follow… The rivers, the forests, the people, & the future.
Our Mission
The Jaguar Rivers Initiative is a bold and urgent continental effort dedicated to restoring, protecting, and connecting ecosystems in the heart of South America.
Through an unprecedented alliance conformed of four leading grassroot organizations, our mission is to safeguard one of the largest river systems in the world, securing the viability of endangered species and the resilience of local communities, thereby contributing to the restoration of global ecological integrity.
The Jaguar Rivers Initiative has been founded by Fundación Rewilding Argentina, Nativa: Naturaleza Tierra y Vida (Bolivia), Fundación Moisés Bertoni (Paraguay) and Onçafari (Brazil).




“Whenever you have success with something, especially when it comes to rewilding, you have no choice but to keep going and expanding the boundaries of what is possible.”
– Kris Tompkins


Our vision is a rewilded, climate-resilient Paraná Basin, where jaguars roam, rivers run free, and communities thrive.
