Rapid ‘Ōhi‘a Death
What is ROD: Rapid ʻŌhiʻa Death (ROD) is newly identified fungal disease currently attacking and killing ʻōhiʻa on Hawaiʻi Island. This fungus clogs the tree's vascular system, depriving the canopy of water, and may kill ʻōhiʻa very quickly. ʻŌhiʻa is the keystone species in Hawaiian forests, and ROD has the potential to cause major ecosystem disturbances that will negatively impact watersheds, cultural traditions, natural resources, and quality of life.
Where is ROD: ROD is found only on Hawai‘i Island. In the park, ROD infected trees have been confirmed in the lower elevations of the Kahuku unit, in the Ka‘ū District. More recently, infected trees have been identified in Kīpuka Puaulu, ‘Āinahou, and Chain of Craters Road near Ko‘oko‘olau Crater. Hundreds of trees have been sampled throughout the park. ROD has not been found in the rainforests surrounding the Kīlauea Visitor Center nor throughout the summit area including Volcano House, Jaggar Museum, and Thurston Lava Tube. It is important to note, patches of dead trees are found throughout the park, and these do not appear to be caused by ROD.
