Rapid Ohia Death is a serious disease affecting ohia trees, which are native to Hawaii. This disease is caused by two invasive fungi, Ceratocystis huliohia and Ceratocystis lukuohia, that infect the trees and lead to their rapid decline and death. The disease spreads quickly through contaminated tools, soil, and water, posing a significant threat to Hawaii's unique ecosystems. Efforts to manage and control the spread include public awareness campaigns and research into resistant tree varieties. Protecting ohia trees is crucial for maintaining the health of Hawaii's forests and the wildlife that depend on them.
