This study, carried out with the support of the GBIF Secretariat and co-authored by researchers from the University of Navarra and GBIF Spain, presents a comprehensive analysis of the biodiversity data hosted by the Spanish node of GBIF on behalf of several institutions in the country. The authors argue that having sufficiently large datasets that are fit for use in science is necessary to effectively understand and cope with the current biodiversity crisis. Assessing the primary biodiversity records served through GBIF Spain, the study concludes that the error level is generally low, and that the available data have the potential to enhance biodiversity research, both locally and globally. However, it notes that many records lack data elements such as georeferencing or taxonomic levels, and that although the remaining information is ample and fit for many uses, improving the completeness of the records would likely increase their usability for science and decision-making.
