| Popis | Alien plant invasions have been systematically studied for more than half a century and we already have extensive scientific evidence of their negative role in the current biodiversity decline. Here we aim to draw attention to expansive plants, i.e. native plant species that exhibit similar ecological behaviour to invasive alien plants, being promoted by recent environmental changes. Some of them can also have various negative impacts on native plant communities and ecosystems. However, they have been much less studied than alien species. Our goal was to create an up-to-date catalogue of expansive species (including aggregates or subspecies where needed) in the Czech Republic, compare their functional traits and ecological strategies with non-expansive native species and provide a list of regions and habitats where they spread. We conducted a questionnaire survey, asking local experts to evaluate the expansive character of preselected species in 17 regions and 27 broadly defined habitat types (66 regional assessments). We critically revised these data and verified the distribution patterns. In total, we identified 126 expansive taxa (116 species, eight species aggregates and two subspecies, for simplicity referred to as species) from 43 families. The most represented were Poaceae (27 spe- cies, i.e. 21%, while only 7% in the native flora), Asteraceae (10 species; 8%) and Rosaceae (10; 8%). Our list comprises a heterogeneous group of plants, which tend to be taller and are more frequently polycarpic perennials than the non-expansive native species of the Czech flora. The highest numbers of expansive species were reported at middle elevations. Thirteen species were considered expansive in all regions: Aegopodium podagraria, Alopecurus pratensis, Anthriscus sylvestris, Artemisia vulgaris, Betula pendula, Calamagrostis epigejos, Dactylis glomerata, Elymus repens, Phalaris arundinacea, Poa trivialis, Rumex obtusifolius, Trifolium pratense and Urtica dioica. Expansive species were most frequently found in anthropogenic habitats, both non-forest (99 species) and woodlands (including plantations and clearings; 73), as well as in mesophilic meadows and pastures (64) and wet meadows (60). We hope that the presented list of expansive plants will trigger further research on them and their potential impacts on plant communities and other biota. |
