New Reef Biodiversity Metrics Framework Aims to Scale Up Coral Restoration

Wire Brief
  • A team led by James Cook University's Morgan Pratchett proposes a new biodiversity accounting framework for coral reefs, published in the journal One Earth.
  • The framework recommends six metrics: hard coral cover, functional diversity, structural complexity, algal composition, fish biomass, and fish feeding diversity.
  • The goal is to create high-integrity, outcome-based biodiversity credits that can attract private investment in reef restoration.
  • The Great Barrier Reef Foundation partnered on the research as part of a broader initiative to unlock new funding for reef restoration.
  • Researchers note roughly half a billion people worldwide rely on coral reefs for daily protein.

To encourage new investments in more effective reef restoration activities, Australian scientists are recommending a new way of measuring biodiversity on coral reefs. A team of Australian environmental scientists led by James Cook University’s distinguished professor Morgan Pratchett proposes a more rigorous and transparent framework in a paper published in the journal One Earth.

Biodiversity credits, such as those associated with the New South Wales government’s Biodiversity Offsets Scheme, are intended to facilitate investment in environmental restoration projects that deliver improvements in biodiversity.

“There’s a massive shortfall in conservation funding, but there is also a clear demand for biodiversity credits … to allow for nature-positive investment by a range of organizations,” Pratchett said.
