UH: Honu emerge as reef defenders against invasive algae in Northwestern Hawaiian Islands

Hawaiian green sea turtles (honu) have been documented for the first time actively grazing on Chondria tumulosa, an aggressive invasive red alga that has spread rapidly across reefs among three of the northernmost atolls in Papahānaumokuākea Marine National Monument (PMNM).

For the first time, nuisance Chondria tumulosa red alga detected beyond Papahānaumokuākea

A red alga first found by University of Hawaiʻi at Mānoa researchers smothering coral reefs in Papahānaumokuākea Marine National Monument has been detected for the first time by the team outside of the marine monument and more than 2,000 miles away.

Scientists have confirmed the presence of Chondria tumulosa, a nuisance alga that can overgrow coral reefs, within the Papahānaumokuākea Marine National Monument, raising concerns about its impact on Hawaiʻi’s coral reef ecosystems.

The team’s mission was to study ways to mitigate the spread of a newly-identified and fast-growing nuisance alga, named Chondria tumulosa, that they say is posing a serious threat to native species.
