Future of saving coral: Legacy Reef Foundation showcasing quest to regrow valuable ocean life force

KAILUA-KONA — Hawaii native Bill Coney and his partner Dr. Susanne Otero are on a mission to save the coral reefs in their home state and around the world.

Located at the end of Makako Bay Drive in the Natural Energy Lab of Hawaii Authority’s Hawaii Ocean Science and Technology Park, their nonprofit Legacy Reef Foundation has launched a project aimed at propagating coral and packaging the process for easy shipment and protocols to places such as Fiji and New Guinea.

And they want to educate people to the importance of our reefs and how we can save them.

One of the ways they wish to teach others about the importance of our reefs is providing a tour including a lecture on coral, a visit to the coral nursery and dive to identify corals and their state of health.

“A few years ago, I realized that the reefs around Hawaii — where I grew up swimming, sailing and diving — were no longer as full of life as they had been just a few decades before,” Coney states on the foundation’s website. “To ensure that my grandchildren will enjoy what I experienced as a child, I dreamed of restoring some of the local reefs.”

That dream became a reality when he met Dr. Susanne Otero.

Together, they created the Legacy Reef Foundation, whose mission it is to restore and conserve coral reefs in Hawaii and around the world and to ensure critical food security for future generations.

That vision is taking giant leaps forward.

What’s at stake

An important first step is understanding what they are.

At an educational lecture on Friday, Lab Manager Andrea Ehlers explained coral is an animal that needs other organisms to live within them and on them in order for all the organisms to survive.

Ehlers provided slides of different corals that are found in Hawaiian waters and explained their unique characteristics. Some common corals in Hawaii include cauliflower, pork chop, antler, popcorn, lobe, finger, rice and mushroom.

She explained that corals are both autotrophic, which means they produce their own food and heterotrophic, meaning they need to get their food from another source.

Algae that live on the coral photosynthesize and consume the carbon dioxide produced by the coral. The algae gives the coral sugars and oxygen.

But coral reefs are in danger because of bleaching events and stressing.

Coral bleaching is when the symbiotic algae leaves the coral. The coral expels it because it thinks it’s going to die because it is in water that is warmer than usual.

Minimizing stressors

Ehlers said resilient corals have survived stressful events and are ideal for collection because it is known they are resistant to those events. They want to propagate their genetics and eventually put them back out on the reef.

Factors that stress coral are global and local.

“As we pump more carbon dioxide into the atmosphere, the world is getting warmer. Additionally the ocean is the biggest sink for carbon dioxide. So it’s taking everything we put into our atmosphere, absorbing it and then it is acidifying,” she explained.

Local stressors include coastal development, runoff and sedimentation.

When there’s not enough plants to hold the sentiment on the land, it will runoff into the ocean.

This creates a big problem in Hawaii, especially with the number of wild ungulates.

“We have a lot of goats here which are also removing the plants and causing the sedimentation to runoff into the ocean,” she said.

Another local stressor is pollution.

Ehlers said abandoned fishing gear comprises 46% of the ocean’s plastic. Once it is abandoned, it keeps on fishing and attaches to the coral. When a big storm comes it will rip the coral up and then use that coral to smash other corals.

Chemical pollution, including sunscreen is another local stressor.

Teaming up

“Our mission here at Legacy Reef Foundation is to establish partnerships with coastal communities,” said Director of Operations Sandra Romer.

“We would like to put everything you need to start a coral nursery in a container and send it off to islands in the Pacific that need reef restoration and then they would re-establish their own reefs and educate their community to keep the reefs from degrading further.

“We are trying to get a real simple system,” she added, “as cheap as you can get that you can put in shipping containers and take to places who don’t have as many resources,” she said.


On the tour, tanks growing coral harvested with an educational permit from Department of Aquatic Resources are showcased. The coral was quarantined, fragmented and put on ceramic or clay tiles to grow.

In their lab, the foundation uses a process called micro-fragmentation meaning the parent colony is cut into small pieces — less than one centimeter square — and glued onto tiles. Since they are exact clones, they grow faster and fuse together when put next to each other.

Romer plans on lectures being held four times a week at the NEHLA Hale Iako building and is hoping to engage school groups as well as locals and visitors.

Two of the weekly tours will include a dive off the coast to identify and observe local coral in various states of distress.

“To remain sustainable in the long-term, I believe funding for LRF will continue to be a mixture of all things but, of course, we would love the tours to take off in 2020 and provide a regular source of income to cover costs. Also, we will be launching Adopt-a-Coral on our website for $20 per month and also, I will be looking for sponsorship for more tanks in the lab,” said Romer.
