The financial cost of non-native species has been published in a new report. "The Economic Cost of Invasive Non-Native Species (INNS) to the British Economy" suggests that invasive species cost 1.7 billion pounds every year. The research was conducted by the international scientific organization CABI for the Scottish Government, Defra and the Welsh Assembly Government and breaks down the effect on each country. It indicates that the economic cost of INNS can be wide ranging and can result in the loss of crops, ecosystems and livelihoods. The cost to the agriculture and horticulture sector alone is estimated to be 1 billion pounds across Britain. See Great Britain Non-native Species Secretariat - Reports for the full report and supporting document.
