Rapid ʻŌhiʻa Death is a serious disease affecting the native Hawaiian tree, ʻŌhiʻa lehua. It is caused by two invasive fungi, Ceratocystis huliohia and Ceratocystis lukuohia, which infect the tree's vascular system, leading to rapid wilting and death. This disease poses a significant threat to Hawaii's forests and ecosystems, as the ʻŌhiʻa tree is a crucial species for biodiversity. The disease was first identified in 2014 and has since spread across the Hawaiian Islands. Efforts to combat Rapid ʻŌhiʻa Death include research on disease resistance, public awareness campaigns, and strict regulations to prevent the spread of the fungi. Protecting the ʻŌhiʻa trees is vital for preserving Hawaii's unique environment.
