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

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

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

  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

  18. 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

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

  20. 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

  21. 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

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

  23. 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

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

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

  26. 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
