ʻŌHIʻA ARE HAWAIʻI'S FOUNDATION 

ʻŌhiʻa (Metrosideros polymorpha), the most abundant native tree in the state of Hawaiʻi, are dying from a new fungal disease. On Hawaiʻi Island, hundreds of thousands of ʻōhiʻa have already died from this fungus, called Ceratocystis. Healthy trees appear to die within a few days to a few weeks, which is how the disease came to be called “Rapid ʻŌhiʻa Death.” This disease has killed trees in all districts of Hawaiʻi Island and has the potential to kill ʻōhiʻa trees statewide.

Updated February 2019

 

Currently, the disease is found on the Islands of Hawaiʻi and Kauaʻi. Ceratocystis huliohia, the less virulent of the two fungal pathogens causing Rapid ʻŌhiʻa Death, was detected on Kauaʻi in May 2018. Ceratocystis lukuohia, the more virulent fungal pathogen causing ROD, was detected on Kauaʻi in December 2018.

WHAT CAN WE DO?

Help prevent spreading Rapid ʻŌhiʻa Death by practicing these five things:

1. Avoid injuring ʻōhiʻa.  

2. Don’t move ʻōhiʻa wood or ʻōhiʻa parts.

3. Don’t transport ʻōhiʻa inter-island.

4. Clean gear and tools, including shoes and clothes, before and after entering forests.

5. Wash the tires and undercarriage of your vehicle to remove all soil or mud.
