Who we are

REWILDING ARGENTINA is a non-governmental organization that works to reverse the species extinction crisis.

We are united by our commitment to recover complete and functional ecosystems through rewilding, by our respect for the intrinsic value of all species, and by the goal of establishing development models that allow rural communities to live in harmony with the natural world.

Formed in 2010 by Argentinian conservationists, Rewilding Argentina inherited the legacy of Tompkins Conservation. We continue collaborating with national and provincial governments, as well as with other organizations and philanthropists, to protect and restore natural ecosystems and to develop biological corridors in Latin America.

Our Leadership

Rewilding Argentina is led by a management team which develops the necessary strategies to achieve our long-term objectives. Our team works in the field, traveling constantly across the length and breadth of the country in order to regularly visit and advance each project.

Our team

Our multi-disciplinary teams live in the areas where we have our projects. This allows us to deeply know and understand the environments where we work, to make accurate diagnosis of threats that they face and to intervene rapidly and effectively in order to assure their restoration and conservation.

Our history


Douglas Tompkins creates The Conservation Land Trust and begins to work on large-scale projects in South America.


The Conservation Land Trust Argentina begins its first project in the country with the acquisition of San Alonso Ranch, an island of 11,400 hectares (28,170 acres) in the heart of the Iberá wetlands. In the following decade, CLTA acquires about 142,000 more hectares (351,000 acres) for conservation and environmental restoration.


The land that became Monte Leon National Park in Santa Cruz Province is donated.


The team of Rewilding Argentina reintroduces the first giant anteaters to Iberá. Soon after, the team begins the reintroduction of pampas deer, collared peccaries, and red-and-green macaws.


Flora and Fauna Foundation is born.


The construction works of the Jaguar Reintroduction Center (CRY) begin in San Alonso Island, Iberá.


Along with other organizations, the donation of the La Fidelidad Ranch is made possible for the creation of El Impenetrable National Park, Chaco Province.

The El Rincón Ranch, which enlarges the territory of Perito Moreno National Park in Santa Cruz Province, is donated.


The land that made possible the creation of Patagonia National Park in Santa Cruz Province is donated.

Tobuna, the first jaguar of the group whose cubs will repopulate Iberá, arrives to the CRY.


The land to create Aconquija National Park in Tucumán Province is donated.

The land to create Iberá National Park in Corrientes Province
is donated.

Rewilding Argentina helps to pass the legislation that creates the National Marine Parks Yaganes and Namuncurá Banco Burdwood II.

Arami and Mbarete are born at the CRY; they are the first jaguars to be born in Corrientes more than seventy years after the species extinction in the Province.


Rewilding Argentina donates the land to create Cueva de las Manos Provincial Park, in Santa Cruz Province.


The first jaguars are released into Iberá Park, eleven years after the beginning of the species’ reintroduction project and seventy years after the extinction of the species in Corrientes.


Rewilding Argentina donates the lands to increase the area of Iberá Provincial Park in more than 50,000 hectares.


Península Mitre Natural Protected Area is created, a conservation landmark achieved thanks to the work of the people of Tierra del Fuego, provincial legislators, and nature conservation organizations—Rewilding Argentina among them.
