1. Module 6 Early Detection and Rapid Response

2. Learning outcomes By the end of this module you should be able to: –Understand the role of early detection and rapid response (ED/RR) –Understand the principles of ED/RR –Know the components of ED/RR and associated issues

3. Module structure Setting the scene Early detection and reporting Assessment Response / action Other issues

4. Management of IAS PREVENTION Early detection & Rapid Response (ED/RR) ERADICATION CONTROL First line of defence Second line of defence

5. What is ED/RR? Early Detection and Rapid Response (ED/RR) = preventing establishment and/or spread of invasive alien species No prevention system in the world can ever be 100% effective, all the time A second line of defence

6. Time Impacts If an IAS is introduced, the chances of eradicating it are best soon after arrival ….

7. A rapid response can minimise environmental and social impacts It can also save money (e.g. the cost of management) e.g The rapid response team for Mimosa in Kakadu, Australia: $2/hectare/year Late response in other area, using biocides: initially $220/hectare/year, plus ongoing maintenance

8. Main components of ED/RR DETECTION & REPORTING ASSESSMENT RESPONSE

9. ED/RR can be applied at: Country borders State or Province borders Protected Areas Offshore islands ‘Mainland islands’ Political boundary Ecological or practical boundary

10. Early detection and reporting 1.SURVEYS Types of Surveys What to look for Networks 2.IDENTIFICATION 3.REPORTING

11. Surveys – why? To become familiar with your environment To notice change To protect biodiversity and livelihoods through rapid response But also: To facilitate exports by being able to certify the absence of certain invasive alien species To fulfil international obligations (e.g. prompt reporting of animal or plant disease) To develop Import Health Standards etc. under IPPC or OIE

12. Surveys General surveys Site specific surveys –Port facilities –End of tunnel??????? –Airport –Protected area Species specific surveys –Brown tree snake –Rats –RIFA

13. What species to look for? species from "black list", "unwanted organisms" list etc. potential invasive alien species that have been introduced in the past, but were successfully eradicated potential invasive alien species that arrived previously but did not establish alien species that are known to have an impact on biodiversity, livelihood, economy or health elsewhere in the world, and for which a pathway into your country may exist However, also look for the UNKNOWN !!

14. Detection networks Active surveillance: people are tasked to look in specific places for specific things Passive: people can spot potential invasions whilst they are doing something else

15. Looking after networks Identification of interested people Encouragement Training

16. Collection & identification Develop collection guidelines –For professionals –For public Ensure IAS are not inadvertently spread while collecting Need access to identification expertise

17. Reporting Professionals: mandates should be clear and known Ensure that public knows where to report suspected sightings Make sure such reports are followed up Give feedback to detection networks Address introduction pathway

19. A new IAS has been detected – what do you do next? Find out more about the situation on the ground Take steps to contain the incursion (as appropriate) Implement Contingency plan (if there is one) Assess the risk Assess the costs and benefits of different options Decide on actions to take

20. Assessment of risks Assess: Probability of establishment, probability of spread Impacts on environment, primary sector, human livelihoods and health etc….

21. Assessment of risks Aim is to assess the species as 'low risk" or "high risk" Be careful with conclusions of "low risk" - apply precaution When assessing potential impacts on biodiversity, invasiveness elsewhere is an important factor

22. DECISION : to act or not to act? Remember: eradication is most feasible and least costly (to environment and finacial) if it can be achieved soon after introduction. A rapid response will cost money…. but not as much as responding too late

23. Response Lead agency Response team (and training) "Operational control centre" Integrating different agencies Support: Technical advisory group, community outreach, "officials" committee, …

24. Contingency plan Where there is high risk, consider preparing a contingency plan Assessment before actual arrival of species This allows action immediately upon detection Requires clarity of mandates & funds

25. As part of response: Provide feedback to strengthen prevention! Give feedback to detection networks Address introduction pathway

26. Associated issues Legal and Institutional issues Funding! Public awareness: more support & more eyes kept open Information sharing

27. Summary Prevention is the first line of defence against biological invasion Early Detection and Rapid Response (ED/RR) is the second line of defence The best opportunity to eradicate is soon after the arrival of a new IAS ED/RR minimises ecological & economic impacts
