Damage costs by non-indigenous species to Southeast Asian countries ($ million).

1Calculation based on the proportional mean value to the agricultural production value which was averaged over 10 years (2001–2010) [26].
2Calculation based on the proportion of pesticide usage in Malaysia, Myanmar and Thailand over 2006–2008 [26].
3Rodents damage to rice production and rodenticide cost, the former was calculated as proportional to the value of rice production of each country, average over 10 years (2001–2010); the latter was calculated for three countries (Malaysia, Myanmar, Thailand) proportionate to their average usage [26]. Damage to cocoa, oil palm and coconuts could not be quantified.
4Damage by the golden apple snail (GAS) to rice production.
5Damage by the White Spot Syndrome Virus (WSSV) calculated as proportional to the production value of aquaculture shrimp species susceptible to the virus in each country averaged over 10 years (2001–2010) [37], susceptible species are banana shrimp (Penaeus merguiensis), blue shrimp (P. stylirostris), giant river prawn (Macrobrachium rosenbergii), giant tiger prawn (P. monodon), Kuruma prawn (P. japonicus), whiteleg shrimp (P. vannamei)[86].
6Damage by the avian influenza virus to the poultry industry was calculated based on the mean loss proportional to the poultry population of the countries infected in the 2003–2004 epidemic. The poultry population was averaged over 10 years (2001–2010) [26].
7Damage by foot and mouth (FMD) disease.
8Losses due to damage by feral cats were calculated as proportional to the land area of each country.
9Losses due to feral pigeons were calculated as proportional to the human population of each country.
10Project cost was not included since detailed budget allocation to beneficiary countries was unavailable.
11Relative economic burden caused by non-indigenous species expressed as a proportion of the national GDP (except for Myanmar where GDP data are unavailable) [81].
