Invasive plant species pose a global ecological challenge, exacerbated by our interconnected world and rapid population growth. These invasions interact with broader ecological shifts, amplifying their reach and impact. Invasive plants disrupt natural biogeographic boundaries, reducing native species’ diversity and abundance, elevating extinction risks, and altering genetic traits and behaviours. They also disrupt ecosystem function, trophic relationships, and native species’ interactions. However, urban ecosystems, with their unique environmental and socio-economic settings, are particularly vulnerable to such invasions. Numerous frameworks and hypotheses attempt to explain invasion success, but a thorough analysis of the hidden attributes enabling alien plants to progress through invasion stages is lacking. This chapter explores the dynamics of biological invasions within urban ecosystems, examining the ecological, socio-economic, and management dimensions. It also focuses on community-level perspectives, particularly exploring how intrinsic traits drive invasiveness and how biotic and abiotic factors influence ecosystem resistance. It examines the ways humans modify environments, at various scales, leading to plant invasions and alter future courses. Climate change’s potential impact on invasive plants underscores the need for ongoing monitoring and modelling. Managing invasive species requires caution, with demand for innovative approaches to enhance control measures. Recent studies highlight the dynamic interactions between urbanization and invasive species, highlighting the human-mediated disturbances and habitat modifications. Strategies for managing invasions in urban contexts are also discussed, providing insights into maintaining biodiversity of urban areas and ecosystem services. This chapter provides a model for understanding invasive species in forest ecosystems to guide research and conservation efforts.
