Mauritius pioneers heat-resistant coral with 98% survival rates

Scientists in Mauritius have achieved a major breakthrough in marine conservation, successfully restoring degraded reefs with heat-resistant coral. The project, led by the Mauritius Oceanography Institute (MOI), reports a stunning survival rate of 98 percent for transplanted corals. This success offers a vital lifeline for coral ecosystems threatened by rising ocean temperatures.

The research focuses on identifying and cultivating coral strains that have naturally survived bleaching events. By propagating these resilient “super corals,” the team is rebuilding reefs that are better equipped to withstand future climate stress. This proactive adaptation strategy is a powerful tool for preserving marine biodiversity.

A Scientific Triumph in the Indian Ocean

The project utilizes a method of coral gardening where fragments are grown in nurseries before being transplanted to the reef. The high survival rate validates the effectiveness of this technique in the specific conditions of the Indian Ocean. It proves that human intervention can accelerate the natural recovery process of damaged ecosystems.

This success is particularly significant for Mauritius, an island nation whose economy and culture are deeply tied to the sea. Healthy reefs provide essential coastal protection against storms and erosion. They also support the fisheries and tourism industries that are the backbone of the local economy. The United Nations Development Programme (UNDP) supports this initiative as part of its climate adaptation strategy.

Scaling Up Restoration Efforts

Building on this success, the MOI plans to scale up its restoration efforts to cover larger areas of the coastline. The goal is to transplant 100,000 coral fragments by the end of the decade. This ambitious target demonstrates a commitment to long-term ecological stewardship.

The project also involves training local community members and dive operators in coral gardening techniques. This community-based approach ensures that the restoration work is sustainable and widely supported. It empowers local people to become active guardians of their marine environment. The Global Coral Reef Alliance provides resources on similar community-led restoration projects worldwide.

Protecting Biodiversity and Food Security

The restoration of these reefs has immediate benefits for marine life. As the coral cover increases, fish populations are returning to the restored areas. This recovery is vital for maintaining the complex food webs of the ocean.

For local communities, healthy reefs mean secure food sources. The return of fish stocks supports artisanal fishing, providing protein and income for families. This link between ecological health and human well-being is at the heart of the project’s mission. The Food and Agriculture Organization (FAO) highlights the importance of coral reefs for global fisheries.

A Model for Global Climate Adaptation

The success in Mauritius offers a hopeful blueprint for other island nations facing similar climate threats. It demonstrates that targeted scientific innovation can enhance the resilience of vulnerable ecosystems. The methods developed here can be adapted and applied to coral reefs around the world.

This project proves that we are not helpless in the face of climate change. By working with nature’s own resilience, we can help secure a future for our oceans. The findings contribute valuable data to the global scientific community’s understanding of coral adaptation. The National Oceanic and Atmospheric Administration (NOAA) tracks global progress in coral restoration science.

    In a landmark achievement for the energy transition, wind and solar power have generated more electricity than fossil fuels in the European Union for the first time over a full year. According to the 2026 Ember report, renewables accounted for 30% of the EU’s electricity in 2025, surpassing the 29% from coal and gas. While gas use rose slightly due to weather conditions, a 20% surge in solar generation and a historic low for coal (9.2%) secured this major victory for clean energy.
