Coral reefs benefit from reduced land-sea impacts under ocean warming.

Coral reef ecosystems are being fundamentally restructured by local human impacts and climate-driven marine heatwaves that trigger mass coral bleaching and mortality. Reducing local impacts can increase reef resistance to and recovery from bleaching. However, resource managers lack clear advice on targeted actions that best support coral reefs under climate change and sector-based governance means most land- and sea-based management efforts remain siloed.

Coral taxonomy and local stressors drive bleaching prevalence across the Hawaiian Archipelago in 2019.

The Hawaiian Archipelago experienced a moderate bleaching event in 2019-the third major bleaching event over a 6-year period to impact the islands. In response, the Hawai'i Coral Bleaching Collaborative (HCBC) conducted 2,177 coral bleaching surveys across the Hawaiian Archipelago. The HCBC was established to coordinate bleaching monitoring efforts across the state between academic institutions, non-governmental organizations, and governmental agencies to facilitate data sharing and provide management recommendations.
