REEFrame is a nature-based solution for restoring degraded coral reefs off the coast of Waikīkī Beach. The project uses innovative technology to create reef structures, called “modules”, that are shaped similar to small natural patch reefs and provide both suitable attachment surfaces for corals and habitat complexity for fish and other marine life. One hundred and fifty modules will be deployed on the seafloor in approximately 40 – 60 feet of water to establish a permanent coral nursery that will support the Hawaiʻi Coral Reef Strategy 2030. The modules were intentionally designed to mimic natural reef structure and complexity, and as a result they provide more interstitial space for shelter and foraging than conventional precast concrete structures. This distinctive feature will enhance ecological function, increase biodiversity, and improve conditions for coral growth and recovery. Each module also incorporates pre-drilled anchor points for the Hawai’i Division of Aquatic Resources (DAR) to secure their “coral pyramids” as well as corals of opportunity from surrounding areas. Once coral nursery operations and outplanting activities are complete, the modules will remain in place as a permanent artificial reef that will further contribute to the long-term resilience of Waikīkī’s nearshore ecosystem.

For generations, Hawaiʻi’s servant leaders cared for the Waikīkī ahupua’a, recognizing the vast importance of our actions on this delicate ecosystem. Once a plentiful habitat for fish and other wildlife, the coral reefs of Waikīkī are now some of the most degraded in Hawaiʻi. We hold ourselves as stewards of this place, and it is with shared kuleana (responsibility) that we as a community work to honor the legacy of the ali’i who have called Waikīkī home.

The restoration of this environmentally and culturally significant ‘āina (land) is central to REEFrame’s mission, guided by the Hawaiian proverb, e hāpai waʻa kākou – if we all help to lift and carry the canoe, we can move it forward. By asking permission to share in this crucial work in collaboration and with pono (goodness), we can once again help healthy corals flourish in the vibrant waters of Waikīkī, Our Home.

With the support of a $9 million grant from NOAA’s Office of Habitat Conservation, REEFrame is a collaborative project led by partners from Conservation International, the University of Hawai’i at Mānoa, the Hawai’i Division of Aquatic Resources, marine technology firm Natrx, marine engineering firm Oceanit, community building nonprofit ClimbHI, and archaeological consulting firm Pacific Consulting Services Inc. (PCSI), among others.

Recognizing the importance of indigenous and other local ocean and cultural knowledge to inform the project, continuous community involvement and consultation is an essential element as we design and build this project to support future generations.

REEFrame was born out of the shared desire to mālama (care for) our beloved island home and protect the ocean reefs that protect us. The hoe (paddlers), wa‘a (canoe), i’a (fish), and makau (fish hook) petroglyphs (kiʻi pōhaku) illustrate our commitment to e hāpai waʻa kākou — if we all help to lift and carry the canoe, we can move
it forward.

Just as the number four has traditionally represented a sustainable harvest from the sea, with each fish tail fitting between the fingers on one hand, REEFrame’s four petroglyphs reflect a deeply rooted passion and kuleana (responsibility) for sustaining the ocean, sea life, the land, and its people for generations to come.

Mahalo to Waikīkī cultural advisor Aunty Ku‘uipo Kumukahi and artist Rosalind Leolani Solomon of the Hawaiian Music Perpetuation Society for the inspiration provided by their music, as well as their guidance and continued collaboration.
