Summary:

Two novel species of the fungal genus Ceratocystis have spread rapidly across humid and mesic forests of Hawaii Island, causing widespread mortality of the keystone endemic canopy tree species, Metrosideros polymorpha (common name: Ohia). The process, known as Rapid Ohia Death (ROD), causes browning of canopy leaves in weeks to months following infection by the pathogen. We combined field studies of leaf spectroscopy with laboratory chemical studies and airborne remote sensing to develop a spectral signature for ROD. Our results provide the spectral–chemical basis for detection, mapping and monitoring of the spread of ROD in native Hawaiian forests.
