Economic Impacts

A report on the economic impact of invasive species in Ireland and Northern Ireland was published in 2013. You can access the report from the link below but the summary findings are:

  • The current estimate of the annual cost of invasive species to the Irish economy is  £161,027,307 (€202,894,406).
  • The current estimate of the annual cost of invasive species to the Northern Ireland economy is  £46,526,218 (€58,623,034).
  • The current estimate of the combined cost of invasive species to Ireland and Northern Ireland is £207,553,528 (€261,517,445).
  • The current estimate of the annual cost of invasive species to the UK economy is £1.8 billion (€2.3 billion). This estimate is based on the work done by Williams et. al. (2010) for Great Britain and the 2013 report.
  • The current estimate of the annual combined UK and Ireland cost is £2 billion (€2.5 billion). This estimate is also based on the work done by Williams et. al. (2010) for Great Britain and the 2013 report.
