Cost of Invasive Non-native Species – Early Eradication Lessens Impact (Dec 15, 2010)
Scottish Goverment.
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.

Great lakesAnnual Losses to Great Lakes Region by Ship-borne Invasive Species at least $200 Million (PDF | 154 KB) (Jul 2008) / More Information about the Economic Impacts of Invasive Species
Great Lakes United.
A U.S. study conducted by the Center for Aquatic Conservation at the University of Notre Dame and University of Wyoming suggests invasive species brought in by ocean-going ships may be costing the Great Lakes region more than $200 million a year in losses to commerical fishing, sport fishing, and the area's water supply.

One study estimates that the total costs of invasive species in the United States amount to more than $100 billion each year. (Pimentel et al., 2004). (PDF | 195 KB)
Invasive species impact nearly half of the species currently listed as Threatened or Endangered under the U.S. Federal Endangered Species Act. (Pimentel et al., 2004). (PDF | 195 KB)
Soybean rust damageSoybean Rust Economic Assessment
USDA. Economic Research Service.
Soybean Rust was detected in the United States for the first time in November 2004. Economic losses to U.S. producers and consumers could range from $640 million to $1.3 billion in the first year of infestation.
Purple loosestrifeOne invasive plant, purple loosestrife, can produce up to 2.7 million seeds per plant yearly and spreads across approximately 1 million additional acres of wetlands each year, with an economic impact of millions of dollars.
Glassy-winged sharpshooterThe glassy-winged sharpshooter, an invasive insect recently detected in California, carries with it the plant bacterium Xylella fastidiosa, a disease that has caused nearly $40 million in losses of California grapes. The disease poses a major threat to grape, raisin, and wine industries, as well as the tourism associated with them. Collectively these are valued at nearly $35 billion annually.
