We present two databases and six spatial layers recording biodiversity information of the six species of ivies (Hedera L., Araliaceae) native to W Europe (Hedera azorica, H. canariensis, H. helix, H. hiberncia, H. iberica, H. maderensis). Each database covers the entire native distribution of each species. Therefore, the databases document the distribution and occurrence of all the European Hedera taxa except for H. pastuchovii subsp. cypria which is a restricted endemic of the south-west of the island of Cyprus. The first database (TaxRev) includes taxonomic, geographic and habitat information from the morphological revision of 2,276 individuals from 1,280 populations. 866 of the records also included point-occurrence data. This database represents the entire native distribution and the morphological variation of each species. The second database (MixOcc) includes the spatial-point occurrence of the six species across their entire native distribution ranges. This database was compiled with the 866 records from the TaxRev database (records with high taxonomic certainty, as they all were examined by the taxonomist of the genus) plus 2,372 records from curated online databases selected from the European regions with low expected taxonomic uncertainty (C and E Europe and the Macaronesian Islands). As a result the database have high taxonomic quality (certainty and coverage) and good geographical coverage for Europe at a large-scale except for France and Ireland. The uploaded fil...
