Coral reefs, often referred to as the “rainforests of the sea,” are among the most diverse and valuable ecosystems on Earth. They provide critical habitats for marine life, protect coastlines from erosion, and support the livelihoods of millions of people worldwide. However, these vibrant underwater worlds are under severe threat from climate change, pollution, and overfishing. In response, numerous innovative and impactful coral conservation projects have emerged globally. These initiatives aim to restore damaged reefs, promote sustainable practices, and educate communities about the importance of preserving these natural treasures.
Here, we explore some of the world’s top coral conservation projects, showcasing the remarkable efforts being made to safeguard these essential ecosystems for future generations.
1. Grenada Artificial Reef Project
Founded in 2013 by Grenada’s dive community, this project aims to combat climate change, storm damage, and overfishing. They install pyramid-shaped artificial reefs made from breezeblocks on barren sea floors. Last year, there were about 80 pyramids with 14 species of coral. Located just off Grand Anse Beach, they are easy to reach by snorkeling from the shore. Volunteers help by counting species, cleaning and maintaining the pyramids, and transplanting coral. Visitors, including children as young as 10, can participate in snorkeling or scuba-diving sessions, which typically run from May to December.

2. Grenada Coral Reef Foundation
This charity collaborates with Grenadian communities. It provides education for aspiring marine biologists and establishes coral nurseries. They also do restoration work and research projects. Additionally, they offer courses on reef restoration and artificial reef technologies. Both locals and scuba-qualified tourists can volunteer.
3. Molinere Underwater Sculpture Park
The Molinere Underwater Sculpture Park is famous for its art and conservation. It now has about 100 sculptures spread over 800 square meters of the Caribbean seabed. Artist Jason deCaires Taylor created it in 2006, two years after Hurricane Ivan hit the area. Last year, around 30 new figures were added to the park. Visitors can see the sculptures by scuba diving, snorkeling, or from a glass-bottomed boat. Corals slowly cover the figures, which helps protect nearby natural reefs. Another underwater sculpture park is planned for the island of Carriacou.
4. Reef conservation in North Queensland
The Forever Reef Project in northeast Australia is the world’s first living coral biobank. It collects a specimen of each coral species for a ‘coral ark’ to repopulate reefs in the future. This acts as an insurance policy against rising ocean temperatures and coral bleaching. So far, 179 of the Great Barrier Reef’s 415 hard coral species have been collected.
Dreamtime Dive & Snorkel, a locally owned tour operator, offers Reef Recovery Days. During these days, science-minded travelers help marine biologists attach coral fragments to Reef Stars to aid regeneration. Cultural guides provide insights into the region’s 60,000 years of traditional ecological reef management.
Citizens of the Great Barrier Reef recruits armchair scientists worldwide to identify corals in thousands of images. This helps scientists and reef managers in their work.

5. The Red Sea, Saudi Arabia
As part of The Red Sea project, AI helps preserve and protect one of the world’s largest coral reef systems. Scientists use AI robotics to monitor over 300 coral sites. This technology allows them to analyze the sites 92% faster than usual. They have discovered new corals that can survive rising sea temperatures. This discovery supports preservation and restoration efforts both locally and globally.
6. Central Caribbean Marine Institute, Cayman Islands
The Central Caribbean Marine Institute (CCMI) studies the reef system of Little Cayman. Their goal is to learn how corals can recover and become more resilient to stress. This research is possible because the reef remains healthy. The island has a small human population, no commercial fishing, and successful conservation efforts. Government initiatives protect key reef species like Nassau grouper and the wider ecosystem.
CCMI works to improve coral restoration techniques and understand how depth, heat, and disease affect coral reef resilience. They use DNA testing to identify the most resilient corals. Visitors can tour the institute, and qualified divers can help collect data by counting and photographing coral.

7. Embratur, Brazil
Many sustainability efforts in the tourism industry are not visible to the public. One example is a policy by Embratur, Brazil’s national tourism board. They give non-material gifts at international events. Instead of swag bags with pens or notepads, visitors receive certificates. These certificates make them ‘coral reef tutors’ and sponsor the regrowth of broken coral pieces.
The reef fragments are nurtured and then replanted onto the Brazilian coast’s barrier reef. This effort is a partnership with a local start-up, authorities, fisherfolk, and their families. By the end of 2024, 800 corals are expected to be transplanted back into the reef off Porto de Galinhas, 60 km south of Recife.

8. Sunlife Coral Restoration, Mauritius
Sunlife, a small group of five sustainably designed luxury resorts in Mauritius, has started coral restoration projects at its Long Beach and La Pirogue properties. They offer hands-on environmental education for kids and adults.
The La Pirogue Marine Research Center uses a micro-fragmenting technique to encourage faster coral growth in its land-based nursery. The results show corals healing 25 to 40 times faster than naturally. Since 2020, more than 2,000 fragments have been replanted. Guests can also learn about coral and other marine life and participate in Sunlife’s ‘Adopt a Coral’ initiative.
9. Coral Gardeners, French Polynesia
Coral Gardeners’ Adopt-A-Coral program is great for encouraging kids to engage with conservation. You can sponsor the rehabilitation of a climate-resilient coral fragment. After naming your baby coral, you will receive a digital card and real-time email updates on its progress in the nursery before it is transplanted onto a reef.
Since its launch in 2017 on Mo’orea near Tahiti, over 100,000 coral specimens have been planted on 11 reefs, with 69,890 planted in 2023 alone and an 82% survival rate. In 2023, Coral Gardeners also opened its first international branch in Fiji, employing five Fijian gardeners and planting over 11,000 corals. Local tribal leaders have given their permission and blessing to the project.

10. Chemical Sunscreen Bans, various, worldwide
Many sunscreens have ingredients like oxybenzone and octinoxate that are toxic to corals, plants, and fish. Unfortunately, ‘reef-safe’ labels are not regulated, so it’s important to read the ingredients list before buying sunscreen. Sunscreens with these chemicals are banned in places like Palau, Hawaii, Aruba, Bonaire, the US Virgin Islands, and some ecotourism reserves in Mexico. To choose reef-safe sunscreens, look for non-nano mineral-based products with zinc oxide and titanium dioxide. These are also good for sensitive skin.
