Resilient Reefs of Jamaica

100 miles surveyed

1-2°C hotter than other islands

>98% mortality in 2023

375 survivors found since

3rd biggest island in the Caribbean

The 2023 bleaching event eradicated >98% of Jamaica's remaining Staghorn and Elkhorn corals, the Caribbean's formerly dominant, reef-building species. We have since continued to identify, rescue and grow surviving, climate tolerant colonies across Jamaica. Our response has been to meticulously scan over ninety miles of fringing reef (over one quarter of Jamaica's coastline) in search of every last remaining survivor. This has led to the inventorying of 300 surviving wild stands, of which 222 have been rescued, banked and undergone asexual propagation in a series of coral nurseries our team has established along the coast through a triad of contracts, engaging and financially incentivising local fisherfolk to care for them on a regular basis.

Webinar hosted by the Atlantic and Gulf Rapid Reef Assessment with participation from White River Fish Sanctuary starting at 52:03 minutes. Here, research lead, Felix, describes early bleaching response and survivor mapping efforts.
TVJ Smile Jamaica
Research Lead at White River Fish Sanctuary, Felix Charnley, describes early resilient coral mapping efforts in the first six months after the 2023 bleaching crisis on Smile Jamaica TV.
Gleaner Interview 2024
Felix Charnley explains what the 2023 coral bleaching event meant for Jamaica and the response subsequently led by the White River Fish Sanctuary with the Gleaner.
TVJ Interview 2024
Research lead, Felix, describes the status of the White River Fish Sanctuary's coral programme 15 months since the devastating extinction-level event. So far that's 119 miles of coastline swum, 276 survivors inventoried island-wide and 99 donors in culture between 2 sites in the Ocho Rios Marine Park, with over 1,500 clones in total.
TVJ Interview Dec 2025
Research lead, Felix, discusses Trelawny’s coral reefs which showed unexpected resilience after Category 5 Hurricane Melissa, recording a 100% survival rate in nurseries.

THE SCIENCE

Mainland Jamaica is the Caribbean's third largest isolated land mass. Sourcing these corals over such a vast sampling range stands to scale locally managed genetic diversity beyond most recorded genotype numbers within Caribbean restoration programs.

Global sea surface temperature data has suggested Jamaica to be 1-2 degrees hotter than much of the Caribbean. Corals to have persisted under such challenging thermal regimes may possess some of the most favourable traits for climate adaptation, making our efforts relevant for reef resilience in Jamaica and beyond.

Our survivors constitute the base broodstock from which to most meaningfully and most effectively render assisted fertilization, symbiont assimilation for thermal tolerance, assisted gene flow and assisted migration in the long term, among other interventions listed as key to ensuring species level survival.

With the effectiveness of coral gardening being questioned against the backdrop of accelerating reef decline, selective measures to curb the imminent collapse of keystone taxa, the creation and safeguarding of new breeding populations, and maximizing genetic diversity in nurseries on far greater scales than before, have become crucial for future restoration.

CALL TO ACTION

Support the cause

In light of compounding threats to these already at-risk species and habitats such as prospective offshore oil drilling within the Walton-Morant block, we aim to expand on our database and extend this system of underwater coral safehavens to the south coast, including Jamaica's outer banks and priority areas still unsurveyed since Hurricane Melissa, to combat the impending extinction of these species.

THE GENE BANK

Trelawny coral rescue initiative

4 critically endangered keystone species

70+ parent colonies

3,000 clones

8 km surveyed

100% survival post-Hurricane Melissa

3 local fishers-cum-coral farmers

3 local female graduate staff

Ours is the first coral reef conservation project in the northern parish of Trelawny, growing extremely rare corals in underwater nurseries in the waters off Duncans/Silver Sands. Our team regularly visits the reserve to propagate and clone these climate smart corals with a view to re-establishing new, reproductive, heat adapted populations at this important site towards the reprisal of their ecosystem role in the long-term.

BORN IN THE COMMUNITY

The Silver Sands project's inception was the result of conversations between our team and stakeholders from the local fishing community inspired to become coral farmers. The program is staffed by two local divers, two regular spearfishers-cum-coral farmers, two University of the West Indies marine biology graduates, and regularly engages 2-3 local boat captains.

HOW DOES IT WORK?

Corals are re-fragmented asexually in order to produce micro-sized headstarts three to four times annually and left to grow throughout the year. Variably after two years, mature corals can be affixed to grow permanently in their natural environment, providing habitat for fishes and other marine life, generating structural complexity within the ecosystem and adding vibrancy to the underwater surroundings.
