On Sand Island, hidden among the hustle and bustle of transport vehicles and industrial businesses, resides the Hawai‘i Coral Restoration Nursery, an organization under the state’s Division of Aquatic Resources dedicated to restoring Hawai‘i’s coral reefs.
Coral reefs, which are vital ecosystems supporting a quarter of all marine species, are under threat from rising ocean temperatures, increased storm intensity, human interaction and local pollution. These factors contribute to coral bleaching, which results from the coral becoming stressed. If allowed to continue, bleaching will lead to coral death and the devastation of local ecosystems and fisheries that depend on healthy reefs.
That is where the Hawai‘i Coral Restoration Nursery comes in. Its mission is to accelerate coral growth beyond what nature can achieve alone. Since Hawaiian corals are known for their slow growth rates, they face prolonged recovery times after disturbances. The organization provides meticulous care and monitoring throughout the growth process and rapidly grows large coral colonies that provide more ecological services, such as more habitats for fish, reduction in wave energy, higher rates of reproduction and higher resistance to water temperature changes or predation. This results in healthier reefs in our state.

This story is one of several featured as part of PBS Hawai‘i’s climate change initiative, Mauka to Makai: Our Kuleana. We are highlighting efforts to educate about and combat problems like threats to coral reefs in our climate change initiative. The initiative includes original content created by our Hiki Nō at PBS Hawai‘i students, spotlighting their views on climate change and the issues their generation faces. Our initiative also shares stories of hope, solution-based projects like this one happening in our communities and in-person events for keiki.
