The Big Five Corridor

Between the towns of El Cóndor and San Antonio Oeste, in the province of Río Negro, lies a biological corridor where five major marine species can be found: sharks, orcas, whales, sea lions, and dolphins. We call them The Big Five because of their ecological importance and their vital role in maintaining the balance of the marine ecosystem. They share these waters with many other species that add to the region’s rich diversity and complexity.

This corridor is not only important for its natural value but is also deeply connected to the region’s social and economic life. Through this project, we aim to strengthen tourism infrastructure and promote local development strategies that link conservation with economic opportunity. Protecting these habitats also helps sustain activities such as small-scale fishing and ecotourism — both of which are essential to coastal communities.

Our mission is to protect these five key species of the San Matías Gulf. Strengthening the region’s protected areas is essential to safeguard its biodiversity and ensure the long-term health of its ecosystem.

To achieve this, we generate scientific knowledge and advance conservation work in collaboration with local authorities, coastal communities, and partner organizations committed to marine protection in the province.

We want the sea to remain full of life — and to continue being a source of livelihoods and well-being for those who call this coastline home.

01 Science & Conservation

We generate scientific knowledge to guide marine conservation in the San Matías Gulf. Through underwater monitoring and field research, we identify key species, map their habitats, and assess the threats they face — building a strong foundation for informed decision-making. This work helps generate valuable baseline data to inform management strategies and strengthen the network of existing marine protected areas in the gulf.

02 Policy and Advocacy

In 2024, we signed an agreement with the Río Negro Secretariat of Environment and Climate Change to share data and co-design a collaborative initiative focused on marine conservation and sustainable development along the northeastern coast of the San Matías Gulf. This partnership opens the door to a project with strong ecological, economic, and social potential — positioning the region as a model for integrated marine management and development.

03 Local Stewardship

Through extensive research and community surveys, we integrate the knowledge, priorities, and concerns of coastal communities into project planning. We also work with municipalities and local organizations to promote responsible tourism and sustainable development — strengthening marine conservation as a driver of new economic opportunities.

04 Communication and Activism

We create compelling narratives to raise awareness about the value of this marine corridor and its species. Through strategic campaigns, we aim to build a shared sense of responsibility and inspire action to protect the ocean.

Milestones

01

Collaboration agreement with the Secretariat of Environment and Climate Change of Río Negro

In 2024, we signed a collaboration agreement with the Río Negro Secretariat of Environment and Climate Change to share data, identify needs, and explore opportunities for a joint project focused on marine conservation and sustainable development along the northeastern coast of the San Matías Gulf.

First scientific expedition to Bahía Creek

In June 2025, we conducted the first scientific expedition in Bahía Creek as part of our research campaign in the San Matías Gulf. In collaboration with Condros and Cethus — two organizations dedicated to marine research and conservation — we deployed underwater cameras and acoustic recorders to document marine fauna in the corridor. The expedition successfully recorded the presence of diverse marine species associated with the region’s key habitats.
