• Native plant invasions can occur within political boundaries under human disturbance and climate change. • Invasion impacts should be assessed by ecological effect, not only by biogeographic origin. • Distinct ecological processes underlying native and alien invasions require differentiated management strategies. • Native invaders reshape local ecosystems through above- and belowground interactions. • Restoring resident biotic resistance may help suppress native invaders with lower invasion risk.
