Published as: Interspecific hybridization may provide novel opportunities for coral reef restoration | Technique: Coral Gardening - Hybridization | Disturbance addressed: General degradation | Genera: Acropora | Method: Crossed two Acropora species pairs from the GBR and examined several phenotypic traits over 28 weeks of exposure to ambient and elevated temperature and pCO2. | Survival of transplants reported by the source: 31.0625% | Post-restoration monitoring: 6.4 months | Authors' conclusion: While elevated temperature and pCO2 conditions negatively affected size and survival of both purebreds and hybrids, higher survival and larger recruit size were observed in some of the hybrid offspring groups under both ambient and elevated conditions. Further, interspecific hybrids had high fertilization rates, normal embryonic development, and similar Symbiodinium uptake and photochemical efficiency as purebred offspring. | Lessons reported: While the fitness of these hybrids in the field and their reproductive and backcrossing potential remain to be investigated, current findings provide proof-of-concept that interspecific hybridization may produce genotypes with enhanced climate resilience, and has the potential to increase the success of coral reef restoration initiatives. | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work.

Published as: Community Reef Restoration Efforts | Technique: Coral gardening - Transplantation | Disturbance addressed: yes | Method: Outplanting coral fragments grown in nurseries (see above record) | Authors' conclusion: MPAs now have 500% more live coral cover and 50% greater species richness of coral than adjacent fished areas, little to no seaweeds, and 30% more food fish, 50% more species of food fish, and 500% more biomass of food fish than the adjacent fished areas, LCC, Species richness, fish abundance and biomass | Lessons reported: Simple asexual coral propagation methods can be quickly learned and effectively implemented by community members for coral restoration efforts. Corals in the genus Acropora, though often utilized in restoration efforts, have been those that are most susceptible to disease and predator damage. Propagating a variety of genera intermixed throughout the nursery helps reduce predation and improves ove… | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work.

Published as: Holistic approach to reef protection (HARP). Phase III: Impacts of bleaching & establishment of coral nurseries. Dhigu (South Malé Atoll) and Kihavah (Baa Atoll), Maldives. | Technique: Coral Gardening - Nursery Phase | Disturbance addressed: yes | Genera: Acropora | Method: Corals of opportunity were transplanted either onto rope nurseries, metal tables, and some fragments were transplanted directly onto degraded areas. These were Acropora fragments cable tied to nails hammered into dead reef. | Survival of transplants reported by the source: 96% | Post-restoration monitoring: 4 months | Authors' conclusion: A dedicated staff member is needed to maintain nurseries, including removal of snails and crown of thorns starfish from frames/corals, cleaning sediment from corals and removing algae. Nurseries need weekly maintenance to survive and thrive. 96% survival on ropes, 87% survival on tables | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work.

Published as: Marine Savers with Four Seasons Resorts | Technique: Substrate addition- artificial reef, Transplantation - fragments | Genera: Pocillopora | Method: Creating coral growing frames (small domes) as substrate for sandy and rubble dominated areas. Cable tie fragments to metal structure | Authors' conclusion: The overall health of the House Reef has been decreasing, with digitate coral species becoming scarce, making coral collection for our frames more difficult. Most remaining Pocillopora colonies are diseased and partly covered in algae, making our Reefscapers work more important as colonies must be collected and propagated to reduce disease mortality. Species of ‘massive corals’ are showing scars from parrot fish feeding, and suffer from crown of thorns predation. | Lessons reported: Channel may be too dynamic a location due to sand movement burying the frames (requires weekly maintenance). Many frames are 'recycled' but not sure if this is due to mortality of attached corals requiring the frames to be reused. Ltd species diversity, and appears to be poor overall | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work.

Published as: Coral Growing - Reef 'Biscuits' and bottle nurseries | Technique: substrate addition - artificial reef, transplantation - fragments | Disturbance addressed: yes | Genera: Mixed | Method: We start by collecting broken coral fragments, which we plant in concrete bases that we call biscuits. We take these to our underwater nursery to grow them into established corals. Once grown, we harvest them and bring them back to our reef, which has been badly damaged by dynamite fishing. We plant them in a bottle reef, where they continue to grow to create a brand new coral reef. | Lessons reported: Our biscuit nursery is the north tip of the island, where the prevailing ocean current arrives at Pom Pom bringing rich nutrients, which is a great environment for promoting coral growth. We lay the biscuits out on the sea bed and tie them down to prevent them drifting away. Over time, the coral grows around the biscuit. When the coral is well-established on the biscuit, it is ready to be harvest… | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work.

Published as: Building Reefs | Technique: Substrate Addition - Artificial reef | Disturbance addressed: yes | Genera: Mixed | Method: Bottles are planted in a concrete base and lowered onto the seabed. They are secured to stop them moving away. Our coral growing project gives us a supply of new coral on small concrete tiles, called biscuits. These are wedged between the bottles. These corals slowly spread across the bottles and incorporate the bottles into the coral skeleton. The bottles slowly disappear and become the invisible reef skeleton. | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work.

Published as: Step Reefs, rubble nets | Technique: Substrate Stabilisation | Disturbance addressed: yes | Method: We stabilise our slope to prevent our regeneration work slipping away. We are stabilising the rubble with soft coral nets, which slows the rubble movement and which the turtles do not destroy. We then plant soft corals and sponges on the nets to hold the rubble together. We also build rubble cages at the top of the slope, which are wire baskets attached to the ground. We fill these with coral rubble and like the nets, plants sponges and corals over the basket to help hold the rubble to the seaf… | Authors' conclusion: Pom Pom Island has a steep slope from the reef crest to the deep water drop off at a depth of around 50 m. All this slope has been seriously blasted in the past by bomb fishermen. All that is left of the original reef are the rubble fragments on a seriously sloping reef. The structures we build are difficult to stabilise. | Lessons reported: Aimed to create small reefs on the steep slopes. These look great initially but too many of them are unstable and deteriorate rapidly. While the corals grow and the fish live on the step reefs we create, unfortunately the slope continues to erode and a beautiful series of steps fixed solidly to the seabed becomes a tumbled mess after turtles scratch and fish dig. | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work.

Newest first, by the date the record was entered here. Records marked from a published source were compiled from the literature and have not been confirmed by whoever did the work — the organisation can claim one as its own. Measured on its own material means the figures describe what the project planted, which is a biased sample of the ecosystem around it.
