Coral reefs sustain life for 1 billion people around the world, but 90% will be extinct by 2050 if we don’t find a solution now.
The coral reef ecosystem, that takes up less than 1% of the seafloor, sustains the livelihoods of up to one billion people and 25% of Marine life.
By 2050, less than 30 years away, over 90% of the world's reefs are projected to die.
That's why a small group of scientists are growing coral 50 times faster and more resilient than in the wild. If they get this right, there will be coral reefs for future generations.
Coral gardening is a conservation technique aimed at restoring and rehabilitating coral reefs, which are critical ecosystems threatened by climate change, pollution, and other human activities. The process involves several steps:
Coral Cultivation: Marine biologists or conservationists grow coral fragments or larvae in nurseries. These nurseries can be underwater structures or land-based facilities where conditions are carefully controlled to promote coral growth.
Coral Transplantation: Once the coral fragments or larvae reach a suitable size, they are transplanted onto degraded or damaged reef areas. This can involve attaching corals to artificial substrates or directly to the reef substrate.
Monitoring and Maintenance: After transplantation, the newly established corals are monitored to ensure they are growing well and to assess the overall health of the reef. Maintenance may include removing algae, repairing damaged structures, or addressing other threats.
Community Engagement: Coral gardening often involves educating and involving local communities in reef conservation efforts. This can help build support for reef protection and sustainable practices.
Coral breeding programs are specialized initiatives aimed at propagating and restoring coral populations, particularly for species that are threatened or endangered. These programs often involve the following steps:
Coral Selection and Collection: Coral species are selected based on their ecological importance, genetic diversity, and resilience to threats. Coral gametes (eggs and sperm) are collected from healthy coral colonies during spawning events.
Spawning and Fertilization: In controlled environments, coral gametes are fertilized to produce larvae. This can be done in laboratory settings or in specially designed coral nurseries.
Larval Rearing: Coral larvae are raised in tanks or other controlled environments where conditions such as water quality, temperature, and light can be carefully managed to promote their development into juvenile corals.
Settlement and Growth: Juvenile corals are encouraged to settle on substrates that mimic natural reef conditions. They are monitored for growth and health as they develop into mature corals.
