Rapid ‘Ōhi‘a Death
What is ROD: Rapid ʻŌhiʻa Death (ROD) is a disease caused by a newly identified fungus. This fungus clogs the tree's vascular system, depriving the canopy of water, and may kill ʻŌhiʻa very quickly.
What are signs of ROD: Infected ‘Ōhi‘a trees may have individual branches or entire canopies of recently dead and still attached brown leaves. The tree's sapwood may have dark and unusual staining and a fruity odor. Additional testing is needed to confirm ROD, since ‘Ōhi‘a may also die from other diseases, drought and injury.
What should I do: Please avoid contact with suspected ROD trees and surrounding areas to avoid spreading this infectious disease. If you suspect a ROD infected tree in the National Park, please complete this report form (pdf 334KB) and deliver it to any park staff or email it. Please include a photograph if possible.
