A collaborative initiative involving scientists from the University of Miami, the Florida Aquarium, and Tela Marine in Honduras is underway to transplant crossbred coral species, aiming to bolster the resilience of Florida's reefs against climate change.

Elkhorn corals, essential for reef health and coastal protection, have seen a dramatic decline, with over 95% lost due to coral bleaching and rising sea temperatures.

On July 1, 2025, divers began planting these corals, marking a significant milestone in a lengthy process led by marine biology professor Andrew Baker.

Currently, more than 200 baby corals are being nurtured in tanks at the research center, with some being transported to Miami for planting.

The transplantation site was strategically selected due to prior coral bleaching that occurred two years ago, highlighting the need for action against rising ocean temperatures.

The corals were secured on small concrete bases in a specific arrangement to facilitate monitoring of their performance compared to native Florida corals throughout the summer.

The team will assess the thermal tolerance of the transplanted corals in comparison to native species, with performance studies planned for the summer.

Healthy corals act as nature's seawall, reducing wave action and protecting coastlines from erosion, which is increasingly vital as the Florida Reef faces severe habitat loss.

Studies indicate that 70% of the Florida Reef, the only living coral barrier reef in the continental U.S., is experiencing significant erosion, impacting the diverse marine life that depends on it.

The transplanted Honduran corals are expected to reproduce and pass on their heat and pollution tolerance, potentially aiding in the restoration of the elkhorn population.

Similar coral breeding efforts are also taking place in Hawaii, where scientists are working to develop 'super corals' that can withstand the effects of global warming.

While introducing corals from other regions carries risks, the genetic link between Honduran and Florida elkhorns, facilitated by ocean currents, may enhance the success of this transplantation effort.
