  1. 1. Invasive Alien Plants and EPPO Sarah BrunelSlovenian Plant Protection Organization 22nd of June 2012
  2. 2. European and MediterraneanPlant Protection Organization • Created in 1951 by 15 countries • Now 50 Member Countries • Under the International Plant Protection Convention (IPPC) • International cooperation in plant protection (plant quarantine and plant protection products) • Bilingual (English/French)
  3. 3. Impacts of Invasive Alien Species
  4. 4. Impact on agricultureSolanum elaeagnifolium competes withmany crops (cotton, maize, lucerne,wheat, olive, etc). In Morocco, losses ofup to 64% in maize without treatment and78% in cotton have been reported.
  5. 5. Impact on land valueAgricultural land infested with S. elaeagnifoliumloses considerable rental and resale value. InMorocco, the value of infested fields decreasedby 25%. In the USA, farms have been abandonedbecause of infestation.
  6. 6. Impact on biodiversityCarpobrotus spp. outcompete otherspecies, and threaten at least 27 plantspecies considered rare, endemic, orprotected in the South of France.
  7. 7. Crassula helmsii outcompetes manynative aquatic plants, in particular therare starfruit Damasonium alisma (oneof the rarest plants in UK).
  8. 8. Costs of controlThe management of 75 km of theGuadiana river in Spain invaded byEichhornia crassipes cost 14,680,000euros from 2005 to 2008.
  9. 9. In the UK, the estimate for control of thetotal area infested by H. ranunculoidesby herbicides is between £250,000 and£300,000 per year.
  10. 10. Impact on healthAmbrosia artemisiifolia provocksallergies. In the Rhone-Alpes region inFrance, 10% of the population issensitive to this species.
  11. 11. A German study assessed the economic impactof H. mantegazzianum to be more than 12million euros annually in the country,distributed among the health system(1.050.000 euros), nature reserves (1.170.000euros), road management (2.340.000 euros),municipal management (2.100.000 euros) anddistrict management (5.600.000 euros).

  24. 24. The EPPO prioritization process for IAPGeneral principles The EPPO process is designed: •A. to produce a reference list of IAP that are established or could potentially establish in the EPPO region. •B. to determine which Invasive Alien Plants (IAP) have the highest priority for an EPPO pest risk analysis (= quick screening tool to identify potential quarantine organisms);Brunel et al. (2010) Article freely available on request
  25. 25. Criteria to produce lists of invasive alien plants Invasiveness categories Combination of spread and impact Spread capacityImpact (highest impact recorded) Low Medium High Invasiveness High (list of IAP) Medium (observ. list) High Low (minor concern) Medium Low

  45. 45. Main elements to be included COLLABORATION4. Encourage other stakeholders inthe supply chain to commit to thiscode of conduct ACTION5. Avoid further spread of invasivealien plants
  46. 46. Main elements to be included ACTION6. Make substitutes for invasivealien plants available

  48. 48. Main elements to be included PUBLICITY9. Apply good practices forlabelling Rosa rugosa (Rosaceae) Rugosa rose, Hedgehog rose Native to Eastern Asia, invasive in Northern and Central Europe. Ensure it does not escape from gardens. Do not plant in or near dunes, where it threatens other species of plants, as well as some animals (e.g. butterflies) and modify the habitat.
  49. 49. Main elements to be included PUBLICITY10. Engage in publicity andoutreach activities
  50. 50. OutcomesCode of conduct available inEnglish, French, Spanish, Polish,etc. 12 countries report nationalinitiatives involving Codesof conduct either on-going orplanned:Belgium, Denmark, Estonia, Ireland,Liechtenstein, Norway, Poland,Slovakia, Slovenia, Spain, theNetherlands, Great Britain.
