Description

The present project was focused on digitizing the data on plant distribution on Dokdo Islands, collected between 1947-2018 by botanists taking part in occasional expeditions to the islands. These data are expected to contribute to the biodiversity management and conservation of these highly inaccessible island ecosystems.

Sampling Description

Study Extent

The Dokdo Islands are the most inaccessible islands in Korea, located at 37°14'26.8'' N and 131°52'10.4'' E, belonging to an administrative district that includes the Ulleung islands.

Sampling

The vascular plant occurrence data treated in this study come from fieldwork from 2012 to 2013 and the botanical legacy papers from 1947 to 2018. Herbarium surveys were conducted in two herbaria, including SNUA (Seoul National University, College of Agriculture, herbarium acronym following Thiers 2018) and KH (Korea National Arboretum). In addition to the authors’ collections, the datasets scattered over different manuscripts in a heterogeneous format were also digitized for the vascular plant occurrences in Dokdo islands (Lee, 1952, Lee and Joo, 1958, Lee, 1978; Sun et al, 2002; Hyun and Kwon, 2006; Lee et al., 2007; Park and Lee, 2008; Park et al., 2010; Song and Park, 2012; Jung et al., 2014; Kim and Lee, 2015; Park et al., 2016; Park et al., 2017; Park et al., 2018). References to the published literature, from which data were obtained for the occurrence data compilation, are presented in the bibliography section of the metadata.

Quality Control

The occurrence dataset for the Dokdo islands was digitized manually from scanned documents of the original papers. The quality control procedures in biodiversity data management were based on Chapman’s (2005) Principles of Data Quality. Scientific names and locality names in the digitized datasets were kept the same as in the original paper. The authors determined the species names given according to the Provisional checklist of vascular plants for the Korea Peninsula Flora (Chang et al., 2014). All scientific names were cross-checked and taxonomically updated using the taxonomic module of BRAHMS (Pouwer et al., 2008); more details on the digitization steps, the structure of the data, and the quality control measures are given below

Method steps

1. The content providers reviewed carefully individual floristic publications to manage the irregularity in the format of the historical papers. All occurrence records were merged into a spreadsheet, and a record of occurrence data holds original species names found at the location. In this stage of the digitization process, obvious typographic errors were corrected. Accepted taxon names and taxonomic classification, as derived from the local checklist (Chang et al., 2014), were included in the spreadsheets. The outcome of the above digitization steps was 843 records with 25 columns containing occurrence data of 108 vascular plant taxa. 2. The layout of the BRAHMS database was made using MS ACCESS. All specimen and occurrence information was captured in the BRAHMS (Botanical Research and Herbarium Management System) database of T.B. Lee herbarium. 3. In literature data, we frequently encountered several uncertain dates for field works, for example, July 13, 2017, September 26, 2017, April 17, 2018, June 19-20, 2018, September 18, 2018, for 68 collections by Park et al. (2018). When the collection date was written as “several dates,” we transcribed the last dates of field works on day, month, year, or their equivalent in eventDate field and the rest of the general information in the verbatimEventDate field. Park and Lee (2008) and Park et al. (2017) published the floristic list of Dokdo islands with many vascular plants pictures. Because these authors have not provided the collection information, we use the publication year as the year of events.
4. All occurrence records were georeferenced, either from the coordinates provided in the paper or from the geographic description of the localities. The coordinate uncertainty in meters for each occurrence was estimated according to the algorithm described by Chapman (2005).
5. Occurrence data in Brahms could be easily exported in various formats, including Darwin Core for uploading to the EABCN IPT. The Darwin Core standard was applied to the BRHMS extract/query file structure to accommodate the relevant information extracted from the publications.
