Overall, 27 trees were selected for inclusion in the study. Six were inoculated with Ceratocystis lukuohia and three were not inoculated and acted as controls, at each of three study sites. The purpose of this dataset is to uniquely identify individual trees included in the study and provide information relating to location, treatment type, date treated and diameter. These data can be associated with data provided in the other six data files. 20190110 20190624 observed Complete None planned East side, Island of Hawaiʻi -155.3838 -154.9525 19.7525 19.4044 ISO 19115 Topic Category biota None Rapid Ohia Death fungal disease Ceratocystis Ambrosia beetles USGS Metadata Identifier USGS:67d3177cd34e1acf3979ceed None Island of Hawaii None Metrosideros polymorpha Ceratocystis Ceratocystis lukuohia Domain Eukaryota Kingdom Plantae Subkingdom Viridiplantae Infrakingdom Streptophyta Superdivision Embryophyta Division Tracheophyta Subdivision Spermatophytina Class Magnoliopsida Superorder Rosanae Order Myrtales Family Myrtaceae Genus Metrosideros Species Metrosideros polymorpha TSN: 27259 Kingdom Fungi Subkingdom Dikarya Division Ascomycota Subdivision Pezizomycotina Class Sordariomycetes Subclass Sordariomycetidae Order Ophiostomatales Family Ophiostomataceae Genus Ceratocystis TSN: 181740 None.

We also thank Dustin Swan of the Big Island Invasive Species Committee for felling and sectioning trees. J.B. Friday and Susan Miyasaka generously provided laboratory space at the University of Hawaii at Manoa Komohana Research and Extension Center. Hawaii Department of Land and Natural Resources invertebrate collection and state forest access permits were issued by Cynthia King and Steve Bergfeld, respectively. We thank Craig Blaisdell for his continued support of ROD studies and access to the Keaukaha Military Reservation. This study was supported by U.S.D.A. Forest Service, Hawaii Division of Forestry and Wildlife, and the U.S. Geological Survey Biological Threats and Invasive Species Program. Windows 10, Excel 365 ProPlus Tree locations were determined using at handheld Garmin GPS device. Datum used was WGS 94. Device accuracy was within approximately 15 m. The diameter of each tree was measured at using a tape measure meant for this purpose.. All data are logical, consistent, and fall within expected ranges. All data were checked for duplications and omissions. The dataset is complete and represents results obtained at the three study sites on the Island of Hawaii during 10 January 2019 - 24 June 2019. NA NA At each of the three study sites, six asymptomatic ohia of similar size to other ohia within the site were selected and randomly assigned to be either inoculated with C. lukuohia or left untreated and monitored as controls. Inoculation of these nine trees (three trees per site) took place on 10 January 2019. Subsequently, a second set of three asymptomatic ohia trees was inoculated with C. lukuohia at each site on 24 June 2019 for a total of six inoculated trees per site. These additional trees were also similar in size to other ohia at each site. 20190110 Robert Peck physical
