TWQ research used to set global restoration challenge

posted in: News | 0

A review of coral restoration methods by Tropical Water Quality Hub researchers has helped set the parameters for one of the world’s most high-profile challenges with millions of dollars up for grabs. The ‘Saving Coral Reefs’ Challenge by XPRISE Ocean Initiative is offering a combined $18 million prize to teams that can demonstrate successful large-scale coral replanting and juvenile coral survival outcomes. Lisa Bostrom-Einarsson at James Cook University is the lead author on a technical report published under a NESP TWQ Hub project to summarise and evaluate coral restoration techniques worldwide. Lisa met with representatives from XPRISE Ocean Initiative at theReef Futures Conference in Florida to help set the parameters for the Saving Coral Reefs challenge, providing vital data on the size and success rates of coral restoration and planting projects around the world. The project studied and evaluated 329 cases of coral restoration from 52 countries, including many only featured in the grey literature, identifying ten different categories of restoration intervention. The technical reports finds that while survival rate for restored corals are quite high (between 60 and 70 per cent), most projects are small and short, with many problems in design, scalability and reporting to be solved before the techniques can be applied on a large scale. The review was co-funded by and conducted in partnership with the Reef Restoration and Adaptation Program. The XPRISE Saving Coral Reefs challenge is expected to launch later in 2019.
