ContextAlien plant invasions challenge biodiversity conservation and ecological restoration. The transdisciplinary nature of plant invasion prevention and management requires a holistic and spatially explicit perspective, to which landscape ecology can contribute.ObjectivesWe aimed to understand how landscape ecology approaches have been applied to investigate the causes, processes, and impacts of plant invasion. Based on this analysis, we synthesized the current research opportunities and challenges in applying landscape ecology approaches to plant invasion studies.MethodsWe followed RepOrting standards for Systematic Evidence Syntheses (ROSES) to conduct the article search, screening, and analysis. We then synthesized the findings through the lens of landscape ecology-based research approaches, theoretical foundations, and methods.ResultsResearch has disproportionately focused on explaining plant invasion patterns in landscapes with landscape structure (patchiness) often used...
