Invasive Species Economics

Leading scientists in the field of invasive species have published the results of their investigations into the economic impacts of invasive species. This page lists some of these references.

March 19, 2008 [New York] - " ...the Department of Environmental Conservation (DEC) has earmarked over a half million dollars to help eradicate non-native, invasive species ... In Jefferson County, the town of Cape Vincent will receive $30,000 to remove hogweed and pale swallow-wort from several sites in the town. " (DEC Grants to Help Battle Terrestrial Invasive Species) (

March 18, 2008 [New York] - " New York recently created a state invasive species council and funded it at $5 million annually . Such funding is difficult to come by, but the cost of not addressing this problem will be far higher in the long run. " (Commentary: Everyone needs to work together on invasive species) (Doug Johnson, California Farm Bureau Federation)

March 17, 2008 [Arizona] - " The state has already spent more than $700,000 over the past two years fighting the glassy-winged sharpshooter , an insect that threatens the wineries of southern Arizona by spreading a type of destructive bacteria... Another recommendation would provide $1 million to help agencies fight harmful plants or animals as soon as they're detected . " (Panel seeks input on fighting invasive species) (Grayson Steinberg, Cronkite News Service,

March 15, 2008 (California] - " ...In California, $87 million in taxpayer funds goes to fighting invasive plants and animals every year ," Cal-HIP says. " (Home invaders: Pretty plants turn ugly fast) (San Francisco Chronicle)

March 14, 2008 [Idaho] - Legislation was introduced Thursday that would authorize the Idaho State Department of Agriculture to take action in curbing quagga mussels, an invasive species that lawmakers and officials fear could devastate south-central Idaho irrigation systems... There is currently no state law that addresses quagga mussels. Last year, the Legislature approved $4 million to invasive plants , principally milfoil, and an underwater plant that spreads rapidly.

The approximately 50,000 nonindigenous species in the United States cause major environmental damage and losses totaling approximately $137 billion per year. (Pimentel et al., 2000)

" Associated damages and costs of controlling aquatic invaders in the United States are estimated to be $9 billion annually ." (Pimentel, 2003)

" The most serious aquatic invading species based on damages and control in terms of millions of dollars per year are fishes ($5400); zebra and quagga mussels ($500); others ($3000) ." (Pimentel, 2003)
