Description: In this chapter, we evaluate nonnative invasive plant species of the urban-rural-natural area gradient in order to reduce negative impacts of invasive plants on native species and ecosystems. This evaluation includes addressing (i) the concept of urban areas as the primary source of invasive plant species and characteristics of urban nonnative plants, including their documented impacts on associated native plants and biodiversity along the urban-rural-natural area gradient, (ii) the most vulnerable land uses and potential barriers to invasion along the urban-rural-natural area gradient, and (iii) possible mitigation of invasions and urbanization using restoration or rehabilitation. Finally, we introduce three possible solutions: (i) use of spatially explicit land use planning and management that places invasion barriers between the urban core and the rural-natural area interfaces, (ii) increasing native and exotic species interactions within the urban core and rural-natural area interface, thereby increasing the number of pathogen and enemy interactions or the loss of novel weapons, and (iii) changing the horticultural trade and people’s behavior, such that propagule pressure is kept below threshold levels required by growing invasive plant populations.
