Management objectives panels A and B show the generalized invasion curve without management and the expected changes 
in the trajectory of the invasion curve with appropriate management actions in (A) terrestrial and closed water systems (including 
lakes and coastal systems such as salt marshes) and (B) marine and connected water systems (including rivers). Post-establishment 
management actions (such as containment and control) are not shown in panel B as they are generally not achievable in such 
systems. In a management context, the first detection (introduction point), lag phase and exponential spread phase are important 
points at which to implement an early detection and rapid response management plan. This figure is conceptual, and the curves do 
not represent actual population dynamics of invasive alien species. In the Management target panels, the white boxes indicate 
the optimal management options at each stage of the biological invasion process. The colour gradient of the managing pathway, 
managing species, managing site and managing ecosystem boxes show how the relative importance of each changes as a biological 
invasion progresses (managing ecosystems is not applicable in marine and connected water systems). In the Actions to achieve 
objective panels, the white boxes indicate the typical management actions needed to achieve each management objective.
