Global change is reshaping plant biogeography, with ever more plant species becoming non-native somewhere (Seebens et al., 2017). A key unresolved question is whether plants with non-native ranges also thrive in their native ranges, as often hypothesized (Paudel et al., 2024), or if their extralimital success coincides with population declines at home. The potential ‘conservation paradox’ (Marchetti & Engstrom, 2016) – where species establish populations outside their native ranges while facing threats within – has been observed in various animal groups (e.g. mammals, birds, reptiles and amphibians; Gibson & Yong, 2017; Lundgren et al., 2024), but has never been assessed globally in plants. Assessing the prevalence of this pattern adds an important dimension to how we understand non-native populations amid rapid biodiversity redistribution. Here, we examine the global extent of naturalized species (plants with self-sustaining non-native populations) that simultaneously face threats in their native ranges (Supporting Information Methods S1). We collated subglobal Red Lists for vascular plants from 103 countries and combined them with the Global Naturalized Alien Flora (GloNAF) database (van Kleunen et al., 2019), which tracks naturalizations in 176 countries. Species names were harmonized using the World Checklist of Vascular Plants (Govaerts et al., 2021). While GloNAF offers near-global data coverage, Red List data remain incomplete in parts of Africa and tropical Asia (Fig....
