The development of invasive non-native plant populations

The development of invasive non-native plant populations (lines) and the costs of containment measures (bars) over time, shown here for no measures (red), isolated measures (blue), and concerted measures (green). Prompt, concerted containment measures clearly pay off: they effectively reduce and control the populations of invasive non-native plants over the long term.
