19 of the best coral reef conservation charities | Rare

Coral reefs are among the most vital ecosystems on Earth. They support fisheries, protect coastlines, and help sustain hundreds of millions of people worldwide. Coral reefs also play a critical role in climate resilience, making their future inseparable from the health of our oceans and coastal communities.

That future is under serious threat. The IUCN Red List of Threatened Species reports that 44% of coral species face the risk of extinction. Scientists agree that what happens to coral reefs in the coming decades will shape marine biodiversity and human well-being. The good news is that research shows well-designed, science-based conservation can slow or even reverse reef decline.

Effective reef protection requires more than restoration alone. It depends on sustainable fisheries, strong local leadership, and supportive policies.

The conservation nonprofits featured in this guide employ strategies to protect coral reef ecosystems, showing how efforts such as science-driven action can help reefs recover and coastal communities thrive.

Key takeaways

• Nearly half of coral species are at risk of extinction, making the work of coral reef conservation charities and nonprofits more urgent than ever as reefs face warming oceans, overfishing, and pollution
• Effective coral reef conservation extends beyond restoration, combining marine protected areas, sustainable fishing, habitat protection, and ecological monitoring to build reef resilience.
• Supporting multiple high-impact coral reef conservation organizations helps scale solutions that protect biodiversity, strengthen coastal communities, and safeguard reefs for the future.

How coral reef conservation charities help make a difference

Coral reefs are the most biodiverse marine ecosystems. Although they cover less than 1% of the ocean floor, coral reefs support at least 25% of all marine species, making them critical habitats for ocean health and the livelihoods of coastal communities. 

With nearly half of coral reef species on the brink of extinction, the need for global conservation is more important than ever. According to research by the International Coral Reef Initiative, 2024 and 2025 experienced the largest coral bleaching event to date, impacting more than 84% of all global reefs.

A combination of local management, restoration, and financial investment is pivotal to increase the resilience of coral reefs and protecting the communities whose livelihoods depend on them. 

In this global effort, coral reef conservation nonprofits play a vital role. For instance, Rare’s people-centered community-led coastal protection shows how community leadership can advance reef protection and promote community wellbeing. Through cooperation with fishing communities when introducing sustainable coastal fisheries management, they create solutions that decrease pressure on coral reefs while supporting livelihoods. 

To mitigate the negative impact on coral reefs and restore them, many nonprofit organizations implement a variety of science-based methods that help:

Restore damaged and dying reefs

Warming ocean temperatures, microplastics, destructive fishing, coral bleaching, and destructive fishing all harm reefs. To decrease the damage and encourage recovery, some coral reef conservation organizations implement projects involving coral nurseries and out-planting, where coral fragments are grown and planted to promote the resilience and health of reef patches.

Aware of the importance of healthy marine ecosystems for ensuring food security, livelihoods, and climate resilience, organizations like Rare collaborate with fishers, local leaders, and government officials, to revitalize coastal fisheries and support community management of natural resources.

Protect marine habitats

Coral reefs, mangroves, and seagrass beds are crucial for maintaining biodiversity, providing coastal protection, and enhancing climate resilience. 

Ensure food security 

Through habitat protection and sustainable management of fisheries, communities can ensure a continuous supply of seafood while preventing overfishing. 

Improve sustainable fishing practices

Overfishing removes wildlife from the water faster than species can reproduce and repopulate. These unsustainable practices impact marine habitats, fish populations, and the coastal communities and economies that rely on these fish and ecosystems. To reduce overfishing, some coral reef conservationists implement programs that educate and advocate for sustainable fishing, set catch limits, and monitor critical spawning regions. 

Advance marine science and monitoring

Without scientific research, coral reef conservation organizations wouldn’t be able to monitor and measure the health of coral reefs and the effectiveness of conservation methods. That’s why some employ a variety of strategies to advance marine science and monitoring, including underwater surveys, satellite tracking, and community-led monitoring programs for data collection and strategy adaptation.

How to support coral reef conservation today

Here’s how personal choices translate to real-life benefits for coral reefs and the coastal communities that depend on them:

Donate 

To safeguard coral reefs, consider supporting organizations that provide scalable, science-based, community-led solutions. Your gift supports sustainable fisheries, habitat restoration, and conservation programs that help people and our oceans thrive. 

Volunteer

Volunteering is a wonderful way to help protect coral reefs. Look for opportunities to participate in beach cleanups and citizen science projects. If you’re travelling, explore eco-friendly tourism opportunities to participate in coral planting, ecological monitoring, and local awareness activities. Support community led initiatives

Conservation delivers the greatest impact when it’s community led. Coastal communities are considered the best stewards of coral reefs, especially when they’re equipped with the knowledge and tools to manage their resources.

This approach is evident in Rare’s work. Through sustainable fishing initiatives, they revitalize coastal fisheries vital for food security, economic progress, and climate resilience, empowering coastal communities to manage them sustainably.

Reduce your own ocean impact

• Reduce single-use plastics
• Choose reef-safe sunscreen that’s free of the chemicals that harm corals and marine life
• Prioritize sustainable seafood or reduce seafood consumption
• Respect wildlife and abide by local rules and social expectations

Choose sustainable tourism operators

When visiting reef areas, choose eco-certified dive shops, snorkeling operators, and companies that follow sustainable and responsible practices, such as maintaining minimal physical contact with reefs, supporting reef monitoring, and contributing to local conservation efforts.

Eco-tours and community-led marine tourism reinvest a percentage of their revenue into coral reef-friendly practices, collaborate with the coastal communities, and implement measures that safeguard marine biodiversity.

Advocate for sustainable fishing

Decades of unsustainable fishing, poverty, and poor law enforcement have caused significant damage to coral reefs, mangrove forests, and seagrass beds. Supporting organizations and policies that promote sustainable, small-scale fisheries helps to protect marine resources and support coastal communities. To start advocating for sustainable fishing, you can:

• •  Support organizations that work directly with local fishers to manage coral reefs sustainably, as Rare does
  • Support seafood policies with conservation in mind
  • Empower restaurants and retailers to use sustainably sourced seafood

Make a difference by supporting multiple types of coral reef conservation charities

Supporting several of the best coral reef conservation charities and organizations is one of the most effective ways to make a real difference.

Although many charities and nonprofits are doing excellent work, opt for those that: 

• • Address multiple aspects of the problem, including restoration, sustainable fisheries, education, and habitat protection
  • Report measurable results through reports, data, and transparent and regular evaluation 
  • Work with coastal communities, especially in the most vulnerable areas 
  • Partner strategically to advance scientific solutions 

Rare distinguishes itself through its community-led approach to conservation. The organization focuses on protecting biodiversity, securing food systems, promoting equity in conservation, and directing public and private capital toward sustainable, community-based, and people-centered environmental solutions. Rare represents a strong and credible option, particularly for donors and individuals interested in behavior change, people-centered solutions, and scalable conservation outcomes.
