  1. Module 5 Prevention

  2. What is Prevention? • Minimizing the risk of moving alien species to countries or ecosystems where they may become invasive

  3. Why is Prevention important? • IAS are a serious problem • urgent attention to the IAS problem is needed • prevention is better that the cure • prevention is most cost-effective (cheapest!)

  4. IAS are a serious problem • You have seen the impacts IAS have on the • economy • environment • human health

  5. Pacific Ocean shipping routes 2003-2003 Urgent attention to the IAS problem is needed • The risks of transferring IAS to new locations increases as more people are travelling and amount of freight is increasing.

  6. Prevention is better that the cure • Once an IAS has established in a new location it can be very difficult, expensive and environmentally damaging to remove.

  7. Prevention is most cost-effective (cheapest!) • The costs of an efficient and effective prevention system are far less than those of dealing with established IAS populations. • Prevention is the first and best line of defence

  8. Where can Prevention be applied? • Pre-border (before it leaves a country) • At the border (before it enters a country) • Post-border (within a country)

  9. Principles of IAS Prevention (see workbook)

  10. Approaches and Tools to IAS Prevention • Legal and Institutional Requirements • Coordination • Collating and Sharing Information • Education and Awareness

  11. Approaches and Tools to IAS Prevention • Risk Analysis • Authorization Procedures • Species List • Quarantine and Border Control • Treatment

  12. Legal and Institutional requirements • These include: • International conventions • Treaties • National laws • Internal policies • Protocols

  13. Coordination • Coordination at international, regional and local levels is essential to develop solutions to common problems.

  14. Collating and Sharing Information • Information needs to be collected and collated to identify potential IAS. • Countries and regions should share information that may impact their neighbors.

  15. Training people to prevent and control invasive species Education and Awareness • Public education is critical in the fight against IAS because human activity is the main cause of the problem.

  16. Risk Analysis • Risk analysis is the process of identifying unwanted species introductions, their associated impacts and management strategies.

  17. Risk Analysis • Applied to species or pathways • Three main components: • risk assessment • risk management • risk communication

  18. Risk assessment steps • 1. Identify the proposed species or pathways Then assess: • 2. Likelihood of IAS being introduced • 3.Likelihood of it establishing • 4.Consequences of establishment Continued…

  19. Risk assessment steps • 5.Level of risk posed without management • 6. Feasibility of managing spread • 7.Feasibility of managing incursions • 8.Any residual threat posed

  20. Risk Management • From the assessment decide whether risk management is required and the treatments required.

  21. Risk Communication • Clearly communicate to stakeholders information on risk assessment and management options. • This leads to better understanding and decisions

  22. Authorization Procedures • Permits and licences are important tools for controlling the movement of alien species between and within countries.

  23. Species List • To filter the intentional introduction of invasive species, a list system should be applied: • Black list = bad • White list = good • Grey list = unknown

  24. Quarantine and Border Control • It is vital to improve procedures to intercept IAS at the border and prevent their spread within a country or ecosystem.

  25. Pre border • Certification • Inspection • IAS proof packaging • Treatment • Pre-quarantine for live plants and animals

  26. Airport quarantine bin Border • Certification • Treatment • Visual inspection • Remote inspection - x-ray - sniffer dogs - cameras • Post-entry quarantine for live plants and animals

  27. Post border • Public awareness • Surveillance - active trapping - public surveillance  Pre-planned response programmes  Pre-planned management programmes

  28. Treatment • Many commodities need to be treated to prevent IAS being introduced.

  29. Summary • Prevention is the first, best and cheapest line of defence. • Prevention approaches and tools can be implemented either: - Pre-border - Border - Post-border • Different organisation and groups of people need education to aid in preventing IAS. • A comprehensive risk analysis on any species is essential. If in doubt keep it out!
