dc.description.abstract | Aim: Plant invasions pose a serious risk to biodiversity, and living collections in botanic gardens are recognized as a potentially important source of alien plant introductions. However, it is not yet known how the risks from botanic gardens compare with other socioeconomic and environmental factors in influencing the regional distribution of alien plant introductions. Location: China. Time period: 840–2018. Major taxa studied: All vascular plants. Method: We compiled a dataset of the locations of first records and introduction pathways for 454 plant species naturalized in China and used boosted regression trees to evaluate the roles of the number, size and age of botanic gardens, local climate, native species richness and trade on the total number of first records of alien plants at both city and province level. Results: Botanic gardens with large living collections played the most important role in influencing the total number of first records of alien plant species at both city and province scale. However, the importance of botanic gardens depended on the introduction pathway of naturalized species. The first records of alien species introduced for horticulture were more influenced by the attributes of botanic gardens. Moreover, the first records of alien species introduced for agriculture were associated with climatic variables, and the first records of alien species introduced accidentally were strongly shaped by trade. Main conclusions: Our results highlight the importance of botanic gardens in facilitating alien plant introductions across a continent. Given the rapid rise in the number of botanic gardens in Asia since 1950, our results point to these as potential hotspots for future plant invasions. Botanic gardens should implement screening procedures to assess the risk of invasion arising from species in their living collections and undertake systematic surveys of their plantings for evidence of plant naturalization. | |
