| Popis | Alien plant species, especially those that are invasive, threaten European biodiversity, disrupt native ecosystem functions and adversely affect human well-being through their impacts on economy and health. Therefore, detailed knowledge about the composition and structure of alien floras at the regional level is essential for studying alien plants’ ecology, distribution and negative impacts. Previous attempts to compile large-scale databases covering the European alien flora (e.g. DAISIE or GloNAF database) were affected by the lack of available national and regional inventories and/or their incompleteness. In our recent overview, we combined inventories of alien vascular plants with online databases and unpublished data from our collaborators (up to 2022) for 55 European territories (i.e, countries and other territories such as large islands). We identified the main data gaps for alien flora in Europe and found inconsistencies among individual territories regarding taxonomic concepts and categorization of species origin and invasion status. This motivated us to prepare an updated and revised database of European alien flora. We compiled all available sources for each territory and harmonized their taxonomy and status. These included (i) national and regional alien plant checklists and unpublished data, (ii) records from large-scale databases (GloNAF, Euro+Med PlantBase and Plants of the Word Online) and (iii) occurrence data from the European Vegetation Archive and GBIF to add taxa not yet included in previous sources. We also added native taxa from the Euro+Med PlantBase and Plants of the World Online for each territory to avoid the confusion of alien and native status for taxa missing in available alien data sources. To revise the status of each taxon, we produced a series of distribution maps showing how it was assessed in original sources for each territory. We assigned each taxon preliminary native or alien status in each territory, for the latter distinguishing the categories of residence time (archaeophyte, neophyte) and invasion status (casual, naturalised, invasive; based on the frequency and population dynamics) and asked regional experts for additional checks. For each alien taxon, we also assigned the region of origin using the TDWG continental scheme (e.g. North America, Europe, Asia temperate). We aim to develop a critically revised and comprehensive database that will be continuously updated and made publicly accessible online within the FloraVeg.EU database . |
