DATASAPROX: standardised dataset from protocolled sampling of saproxylic beetles in continental France and Corsica

As part of the DATASAPROX project, we created an occurrence dataset of the saproxylic beetles from continental France and Corsica focused on protocolled data from flight interception traps. For this, we solicited the main national data producers and collected their raw data as well as the associated trapping metadata (e.g. type of trap). Once retrieved, all data went through selection and reformatting steps, including the removal of duplicates between datasets and the standardisation of taxonomic information according to the TAXREF v.18 format. We considered data from specific aerial interception traps: crossed window (©Polytrap, ©Pimul, ©Crosstrap, ©Portrap), multi-funnel (Lindgren) and window (single glass) traps. We aggregated a dataset constituting 675,525 records from 21 data producers and providers, including 485 identified projects. This dataset includes a total of 71 families, 153 subfamilies, 738 genera and 2039 species of saproxylic beetles. Data points encompass all 96 counties from continental France and Corsica for a total of 8969 geographic points and 66,202 samples. This new standardised dataset on saproxylic beetles offers new opportunities for ecological studies and conservation applications.
