A successful coral transplant gives scientists hope for the Great Barrier Reef


Coral was raised in a part of the Great Barrier Reef that was successfully transplanted into another area, Australian scientists said on Sunday, in a project they hope will restore damaged ecosystems around the world.

In a trial on Garza Island on the reef On the east coast of Australia, researchers collected large numbers of eggs and coral offspring late last year, turned them into larvae and then transplanted them to damaged reef areas.

When they returned eight months later, they found juvenile coral that had survived and "The success of this new research not only applies to the Great Barrier Reef, but has potential global significance," said lead researcher Peter Harrison of Southern Cross University.

"It shows that it can begin to restore and repair damaged coral populations where the natural supply of coral larvae has been compromised."

Harrison said that his larval restoration approach in mbad contrasts with the current method of "coral gardening" to break the healthy coral and stick healthy branches on the reefs with the hope that they will grow back, or grow coral in nurseries before transplanting.

He was optimistic with his approach, which was successfully tested in the Philippines in a highly degraded reef area by blasting fishing could help the reefs recover on a larger scale.

"The results are very promising and our work shows that adding higher densities of coral larvae leads to a greater number of successful coral recruits," he said.

The Great Barrier Reef, the largest living structure on Earth, falters after a second consecutive year of coral bleaching due to warming sea temperatures linked to climate change.

The chief scientist of the Great Barrier Reef Marine Park Authority, the government agency that administers the area, said it was necessary to make such efforts amid the accelerating impacts of climate change.

"The success of these The first trials are encouraging: the next challenge is to incorporate this into a larger-scale technology that makes a difference in the Reef as a whole," said David Wachenfeld.
