Global Naturalized Alien Flora (GloNAF). Open access data to support research on understanding global plant invasions.

This dataset is a snapshot of the Global Naturalized Alien Flora (GloNAF) database, version 2.02.  GloNAF is a continuously updated, curated compilation of alien naturalized vascular plant inventories for geographic regions from around the world. The dataset has 16,429 unique taxa reported as naturalized or invasive and covers 1,343 regions (including 427 islands) from 336 data sources. For each region, the status (invasive, naturalized) is provided as listed in the original source.  We provide the scientific names included with the original data source, and the matching accepted name or synonym of the taxon as given in the World Checklist of Vascular Plants (WCVP) Version 12. In addition, we provide an ESRI shapefile of polygons for each region. We also provide several variables that can be used to filter the data according to quality and completeness of alien taxon lists, which vary among the combinations of regions and data sources.

NOTE: In the previous version of GloNAF, some of the taxa names listed in the 'taxa_accepted' column  of the 'glonaf_taxon_wcvp' table were not WCVP accepted names and were associated with an incorrect 'accepted_plant_name_id'. These taxa names have been replaced with the correct accepted name and accepted plant name id as provided by the WCVP version 12. Please note that species with a taxonomic status of 'Artificial Hybrid' are assigned an accepted plant name id in the WCVP. These are identified in the 'wcvp_taxon_status' column of the 'glonaf_taxon_wcvp' table .
