WOODIV v2, more occurrences, functional traits, and a time-calibrated phylogeny for Euro-Mediterranean trees

The WOODIV v1 database provided occurrences at 10 km spatial resolution, traits and phylogenetic data for all 210 species (and 35 subspecies, totalling 245 taxa) in the Euro-Mediterranean Basin. While this reliable and readily accessible database has been of crucial help to investigate macro-ecological and biodiversity conservation questions, important knowledge gaps remained. To fill these gaps, we present an updated and extended version of the WOODIV database. (i) Occurrence data were updated from sources already considered in v1, three additional sources and an intensive field work campaign in Italy where occurrence data were scarce in v1, allowing to highly increase spatial coverage and data completeness. (ii) Besides increasing taxonomic coverage of traits already considered in v1, the traits data set has been extended to 15 new functional traits encompassing morpho-anatomy, reproduction and phenology, using new traits measurements from the field and data compilation from botanical literature not available in other databases. (iii) Finally, a new time-calibrated phylogeny for all 210 tree species was built and made available.
