Pests or pathogens that affect trees have the potential to fundamentally alter forest composition, structure and function. Throughout the last six years, large areas of otherwise healthy ‘ohi‘a (Metrosideros polymorpha) trees have been dying rapidly (typically within weeks) in lowland tropical wet forest on Hawai‘IiIsland, USA. This mortality is quite distinct from previous well-documented ‘ohi‘a dieback episodes driven by cohort senescence. Assessing spatial distribution, stand impacts and rate of Ceratocystis fimbriata inducedʻōhiʻa (Metrosideros polymorpha) mortality in a tropical wet forest, Hawai‘i Island, USA.
