The guiding principles on invasive species adopted by the prioritize management actions (see MedPAN Draft IAS
Convention on Biological Diversity (2002) and the Strategy, 2012)
Guidelines for Protected Areas (Tu, 2009) reflect these
findings: prevention should be the priority, followed by
early detection, rapid response and possible eradication
when prevention fails. Following these recommendations,
the Draft Marine Invasive Alien Species Strategy for the
MedPAN Network provides a framework for common and
individual management actions for MPAs (MedPAN Draft
IAS Strategy, 2012).
Each MPA management plan should have an IAS strategy
integrated into the overall plan. The plan should cover all
stages, from developing and implementing specific
management plans for high-priority invasive species in
vulnerable sites, to identifying opportunities to help
prevent new invasions and the spread of established
invaders (Fig. 13). Moreover, it should also focus on
increasing awareness among the general public and
specific groups, building collaboration programmes to
address solutions with research and stakeholder groups, Fig. 13. Management strategy against invasive species. From
