How much does it cost to restore coral reefs?
Coral reef restoration is expensive, with costs estimated from $1,717 up to $2,879,773 USD per hectare (Bayraktarov et al., 2015). This enormous range is due to the different phases of restoration and various methods employed where research suggests that current costs outweigh benefits (De Groot et al., 2013).

“To replant the Great Barrier Reef by planting fragments that cost $5 a piece to grow in the aquaculture facilities across 40,000 km² of the Great Barrier Reef would cost $200 billion,” Professor Hoegh-Guldberg said.
Are restoration projects enough to save our coral reefs?
Researchers Say Current Measures Are Not Enough to Save Reefs. Terry Hughes, a prominent coral reef researcher believes that current measures are insufficient.
What methods do scientists use to improve coral reefs?
One option is to create more marine protected areas—essentially national parks in the ocean. Scientists say creating marine refuges, where fishing, mining, and recreating are off limits, make the reefs healthier, and so more resilient.
What are methods that scientists use to improve coral reefs or to control the factors responsible for the deterioration of coral reefs?
Raising larvae in the lab, scientists are crossbreeding species to become more heat tolerant. This can also be done by raising coral in hotter water. Another technique is to focus on algae, which coral rely on for oxygen and other nutrients.
Is coral Restoration expensive?
While the median reported cost over all observations is around 400,000 US$ to restore one hectare of coral reef habitat, costs reported for the techniques most commonly applied ranged between 6,000 and 4,000,000 US$ per hectare.
Is coral farming expensive?
“When we expose those corals to really warm temperatures, they are even performing better [than before],” he said. But Banc-Prandi said there are also limitations to coral farming on land. It is very expensive and great care must be taken to prevent transplanted corals from being destroyed by natural hazards, he said.
How much is coral reef worth?
By one estimate, coral reefs provide economic goods and services worth about $375 billion each year.
Is Coral Restoration effective?
Overall, coral restoration projects focused primarily on fast-growing branching corals (59% of studies), and report survival between 60 and 70%.
Is Coral Restoration working?
Mote Marine Laboratory scientists have restored 100,000 corals to Florida's Coral Reef—an exciting milestone. In 2020, several of our restored corals spawned, engaging in sexual reproduction to produce new generations of corals.
In what ways could damage reefs be saved and rehabilitated?
Conserve water. The less water you use, the less runoff and wastewater that will eventually find its way back into the ocean. Volunteer in local beach or reef cleanups. If you don't live near the coast, get involved in protecting your watershed.
