The updated Global Naturalized Alien Flora (GloNAF 2.0) database.

Area of Science:

• Ecology
• Botany
• Biodiversity Science

Background:

• Biological invasions pose significant ecological and economic challenges globally.
• Understanding the patterns and drivers of plant naturalization is crucial for conservation and management.
• Existing databases require regular updates to reflect new data and taxonomic changes.

Purpose of the Study:

• To present GloNAF 2.0, an updated and expanded global database of alien naturalized vascular plants.
• To detail the major improvements in taxonomic standardization, data completeness, and geographic coverage.
• To align the GloNAF database with FAIR data principles for enhanced accessibility and reusability.

Main Methods:

• Compilation and curation of vascular plant inventories from global geographic regions.
• Standardization of taxonomic names using the World Checklist of Vascular Plants (WCVP).
• Inclusion of new records and removal of outdated data to enhance database accuracy and scope.

Main Results:

• GloNAF 2.0 contains 16,429 taxa, a substantial increase from previous versions.
• The database now covers 31% more geographic regions compared to GloNAF 1.2.
• Significant additions of 117,229 new records, increasing naturalized taxa by 26%.

Conclusions:

• GloNAF 2.0 is a comprehensive and accessible resource for studying biological invasions.
• The updated database facilitates research on the drivers and consequences of plant naturalization.
• Adherence to FAIR data principles ensures the long-term utility and impact of the GloNAF dataset.
