(No Blue No Green)

Rewilding Argentina’s Marine Program

As a response to the current crisis of global extinction and with the objective to preserve life on this planet, in 2017 the Rewilding Argentina Foundation created the Marine Conservation Program “Sin Azul No Hay Verde (No Blue No Green)”, in order to protect the habitat of the Patagonia oceans and coasts and the species that live there.  

Our objective is to protect 30% of the Argentine ocean in order to assure the conservation and regeneration of its ecosystems, through the creation of a network of marine and coastal protected areas.  

The Argentine ocean is one of the most biodiverse marine habitats in the world and is currently in grave danger. Some of the biggest threats are overfishing, contamination of its waters and the resulting extinction of species.

It is an urgent global need to conserve the habitats of the Argentine ocean.

Martina Sasso
Coordinator for the Marine Program “Sin Azul No Hay Verde”

A creative advertising agent and movie director, Martina also studied conservation in order to dedicate herself to the protection of biodiversity in the midst of the growing extinction crisis. In 2017, she began to work with the Rewilding Argentina Foundation as one of the founders of the marine conservation program. Along with a multi-disciplinary team, she led the creation of the first protected marine areas in Argentina. Currently, the marine program is focused on adding more marine and coastal protected area within Argentina’s jurisdiction and to halt the advance of industry and development that is damaging to marine ecosystems and their functionality.



One of the last pristine places on the planet

Península Mitre


Peat bogs, meadows and marshes, Patagonian mountain forest and kelp forests.

Carbon Sequestered:

318.6 million metric tons

Conservation Value:

Species that are vulnerable to or at risk of extinction, like the southern river otter, the humpback whale and the Common Steamer duck.

Coordinating Team:

Ángeles De La Peña
Sin Azul No Hay Verde

Angie studied law and worked in another foundation and in Argentina’s Chamber of Deputies before beginning to work with Sin Azul No Hay Verde, the marine conservation program of Rewilding Argentina. She joined the team in order to collaborate in the process of creating Argentina’s first two Marine Protected Areas, Yaganes and Namuncurá-Banco Burdwood II, which were approved in December 2018. She is currently based in Ushuaia and coordinates the project to ensure protection of Peninsula Mitre.

Península Mitre is located in the farthest east part of the Isla Grande de Tierra del Fuego, at the southern tip of Argentina. The area that is proposed for protection covers approximately 300,000 hectares of land and 200,000 hectares of sea, including the waters that surround Isla de los Estados.

This region has managed to stay almost completely intact, in its original wild and indomitable state.  Its off-shore waters are a union of two oceans, the Pacific and the Atlantic, a productive commingling in which inhabit, migrate and feed numerous species that are vulnerable, threatened and in danger of extinction, like the humpback whale and the flightless steamer duck in the sea and the southern river otter on the land.  

In addition, there are vestiges of the Haush indigenous culture, evidence of more than 500 shipwrecks and an infinite number of species of marine and terrestrial flora and fauna.

Why is it urgent to protect Península Mitre?

Legal protection of the Península Mitre would symbolizes a ray of hope in the face of the global climate crisis and the crisis of species extinction across the planet.  

In all of Argentina, Península Mitre is the most important region for carbon sequestration —a key characteristic for the mitigation of global warming. What is its secret? The peninsula has the largest concentration of peat bogs in the country. Peat bogs are a little-known ecosystem, which globally can store more carbon than all of the forest biomass of the planet. 

A project with 30 years of history

The first exploratory expedition that was done on Península Mitre took place more than 30 years ago, and during this survey the need to conserve the area was identified. The different bills that have been presented to protect the region have been transformed over time; however, all share the same spirit of conservation and the final goal to designate the peninsula as a Natural Protected Area.  

Up until the present, the natural attributes and the archeological remains found there have largely been preserved. But this area faces new challenges such as theft of archaeological treasures, the pressure from exotic species, and, more than anything, the consequences of an extractive economic mode that puts at risk the very elements that make this place a unique natural area and an exceptional treasure for humanity.

Ocean of the Continental Shelf.

Combined area:

90,000 square kilometers.

Important Conservation Attributes:

Extensas áreas marinas casi prístinas, que son fuente de alimento para una gran cantidad de mamíferos marinos y aves, entre ellos la ballena fin, la ballena sei, y el cachalote.

Yaganes and Namancura-Banco Burdwood II National Parks

Yaganes and Namuncurá-Banco Burdwood II were the first marine national parks created within the Argentine Marine Protected Areas System in December 2013.

The Namuncurá-Banco Burdwood II National Marine Park includes sea beds 4000 meters deep and submarine canyons that contain abundant biodiversity. This region is part of a crucial migratory route for numerous mammals and birds, who find there an important source of food on their long journeys.

Yaganes National Marine Park is largely unexplored, although there is evidence that shows the existence of undersea canyons and mountains with a high diversity of species. This is a critical feeding grounds for the sperm, sei and fin whales, as well as being one of the most pristine ecosystems on the planet.
