A BBC story on the restoration of the southern Belize reef after Hurricane Iris.When Hurricane Iris hit southern Belize in 2001, the country's magnificent corals were destroyed. But within 10 years, a radical restoration project brought the reef back to life.
With the caye split into two and corals smashed into rubble, the underwater world at Laughing Bird Caye National Park off the coast of Belize looked nothing like the vibrant and colourful place that had thrived with life before Hurricane Iris swept across it in 2001. The storm left the water murky and muddy, while rotting dead creatures washed ashore.
When Lisa Carne first visited the island in 1994, there were so many large, bright reddish-orange interlocking elkhorn corals that she could hardly swim through or around them. The reef was abundant in fish, corals, lobsters, crabs, sponges and sea turtles. But after the hurricane all of this was destroyed. With only a few surviving corals, the scene looked more like a graveyard.
It was not the first time Carne had seen a dead reef. In 1995, she moved full time to Belize from California, and volunteered as a research assistant at Carrie Bow Cay, a Smithsonian field station. She witnessed the effects of the first coral bleaching event in Belize, home to the second longest barrier reef in the world. Bleaching events leave the structure of corals intact, but strip it of the algae that live in an endosymbiotic relationship with the coral polyps. Some coral recover from such events as the algae returns, although many die.
Hurricane Iris was catastrophic in a different way. It not only killed corals but uprooted their structure too, making recovery even harder.
Carne immediately wanted to start replenishing the reefs by planting corals, but it took many years to convince any funders that her idea was viable. People argued, and still do, that without solving the problems that cause corals to die, putting them back on the reef made no sense.CLICK HERE to read the story...
