Signs of Coral Reef Recovery

Marine scientists have reported encouraging signs of recovery on a badly damaged coral reef.

Surveys carried out this spring found that new coral now covers almost a third of the reef.

Just five years ago, rising sea temperatures had destroyed much of the coral in the area.

Researchers believe that a run of cooler summers has given the reef time to recover.

However, they warn that the improvement could be reversed by another extreme heatwave.

Local authorities are now considering limits on fishing and tourist boats in the area.
