A new study has found that corals in the Keppel Islands off the coast of Queensland, Australia, have shown remarkable resilience following a severe bleaching event in 2016.

The study, published in the journal _Coral Reefs_, found that coral cover on the Keppel Islands increased by an average of 14% between 2016 and 2019. This increase was driven by the recruitment of new corals and the regrowth of damaged corals.

The researchers believe that the resilience of the Keppel corals is due to a number of factors, including:

* High levels of genetic diversity: The Keppel Islands are home to a wide variety of coral species, which means that there is a greater chance that some corals will be able to tolerate bleaching than others.

* Low levels of human activity: The Keppel Islands are relatively isolated from human activity, which means that they have been less affected by pollution and other stressors.

* A healthy ecosystem: The Keppel Islands have a healthy ecosystem, with a high abundance of fish and other marine life. This helps to support the corals and provide them with the resources they need to recover from bleaching.

The study's findings are encouraging and suggest that coral reefs can recover from severe bleaching events. However, the researchers caution that coral reefs are still facing a number of threats, including climate change, pollution, and overfishing. It is important to take action to protect coral reefs and ensure their long-term survival.
