ʻŌHIʻA ARE HAWAIʻI'S FOUNDATION 

ʻŌhiʻa (Metrosideros polymorpha), the most abundant native tree in the state of Hawaiʻi, are dying from a fungal disease referred to as “Rapid ʻŌhiʻa Death.” ROD has been found on Hawaiʻi Island, Kauaʻi, Maui, and Oʻahu. ROD is comprised of two pathogens, Ceratocystis lukuohia and Ceratocystis huliohia. C. huliohia is less aggressive and has been found on each of the four islands. C. lukuohia is highly aggressive and has been identified on Hawaiʻi Island and Kauaʻi. Hundreds of thousands of ʻōhiʻa have died from this fungus on Hawaiʻi Island alone. Find out how you can help.

Updated February 2019

 

Rapid ʻŌhiʻa Death disease has been found on the Islands of Hawaiʻi, Kauaʻi, Maui, and Oʻahu. Both Hawaiʻi Island and Kauaʻi have confirmed Ceratocystis lukuohia (destroyer of ʻōhiʻa) and Ceratocystis huliohia (disruptor of ʻōhiʻa), the two fungal pathogens causing ROD. While C. lukuohia is a more aggressive fungus than C. huliohia, either species will kill ʻōhiʻa. In July 2019, a single tree infected by C. huliohia was detected on Maui and a single tree was also detected with C. huliohia on Oʻahu
