Research led by the University of Hawaiʻi at Mānoa Hawaiʻi Institute of Marine Biology (HIMB) has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.

Using ecological and marine environmental conditions, the Multi-Factor Coral Disease Risk product predicts the risk of two diseases across reefs in the central and western Pacific and along the east coast of Australia. An article introducing the new tool was published in Ecological Applications.

The tool can be accessed through the U.S. National Oceanic and Atmospheric Administration (NOAA) Coral Reef Watch program, and can help end users detect early changes in the environment and better protect coral reef ecosystems.

“Partnering with NOAA Coral Reef Watch, our team developed ecological forecasts to predict the times and conditions when coral disease outbreaks are most likely to occur,” said NASA-funded Principal Investigator and HIMB Interim Director Megan Donahue.

“We are really excited about this new tool,” said lead author, Jamie Caldwell, of High Meadows Environmental Institute at Princeton University. “Users can employ this tool to make decisions about how to manage coral health, similar to how we use weather forecasts to decide how to pack for an upcoming trip.”

More than half a billion people depend on Earth’s coral reefs, and ensuring their resilience in the face of many threats is an ongoing challenge for managers. Tools like this help ensure these vital ecosystems survive.
