Moreton Bay Coral Discovery

Scientists have discovered and mapped out new parts of the coral reef system in Moreton Bay with the hope the work will help inform decisions to better protect it.

The area’s secret spots were revealed during the most detailed reef mapping ever done of the south-east Queensland coastal region.

“On Goat Island, not far from where the ferry travels to go to North Stradbroke Island, there’s quite a lot of coral there which most people would be really surprised to know,” Reef Check Australia’s Jennifer Loder said.

She said the mapping project, that also involved the Healthy Waterways organisation, provided the clearest picture so far of what was beneath the surface of the busy boating playground.

“You’re looking at these sites on a map going, maybe there’s something there. Then you dive over the side to have a look and all of a sudden are greeted with these coral habitats that you totally didn’t expect,” she said.

The region hosts more than 60 species of coral — more than some of the world’s most popular dive sites.

‘You will see hard corals, soft corals, branching and massive’

The volunteers handed their diving data to mapping experts at the University of Queensland (UQ) who used existing maps and new, clearer satellite images to detail what was living where.

“In some places you will see mud. But in other places you will see hard corals, soft corals, branching and massive,” UQ’s Chris Roelfsema said.

“South-east Queensland reefs are impacted by sediment and nutrients and fishing pressure, as well as acute events such as floods.”

Scientists hope the mapping will help inform conservation decisions to protect the small but important reef system.
