About ROD (Rapid ʻŌhiʻa Death)
A new fungal disease is currently attacking and killing ʻōhiʻa (Metrosideros polymorpha), the most abundant native tree in the state of Hawaiʻi. On Hawaiʻi Island, hundreds of thousands of ʻōhiʻa have already died across thousands of acres from this fungus, calledCeratocystis fimbriata. 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 the South Hilo, Puna, Kaʻū and Kona districts of Hawaiʻi Island and has the potential to kill ʻōhiʻa trees statewide.
