Governance Economics of Biological Invasions Selected CBA Case Studies Conclusion
Ecological Aspects of Biological Invasions (2/3)
Conceptual model by Planty-Tabacchi (1993):
introduction
colonization (settlement)
development, either destruction or integration extension
Williamson and Fitter (1996): rule of 3 times 10. In general, 1000 imported species→100 considered introduced→10 naturalized→only 1 invasive.

International laws: convention on biological diversity in 1992, and the Berne convention (also in 1992).
Amendment to the International Convention on Plant Protection (ICPP), which now includes ”pest quarantine”.
CBA is now adopted as a guide for plant protection:
recommendations of ICPP, in US, Australia and New-Zealand.
Also recommended by European Commission regarding decisions affecting biodiversity.
CBA is compatible with establishment of white/black lists in international trade
