Abstract : Executive Order (EO) 13112 defines invasive species as non-native plant, animal, or microbial species that cause, or are likely to cause, economic or ecological harm or harm to human health. Such species have been introduced outside of their natural geographic range by intentional or unintentional human actions (VISC 2005), and have since become naturalized, establishing viable reproducing populations. The problem of invasive species (also referred to as non-native, non-indigenous, exotic, alien, noxious, weed, and pest species) continues to increase in magnitude as new invasive organisms are introduced around the globe, currently established invasive species are dispersed across the landscape-invading approximately 700,000 hectares of wildlife habitat per year in the U.S. (Babbit 1998 in Pimentel et al. 2004)-and further research manifests the negative impacts to native ecosystems that arise from their presence. Researchers calculate that invasive species threaten the existence of somewhere between 35 and 50 percent of endangered and other protected species (Wilcove et al. 1998, Westbrook et al. 2005). Beyond degradation to ecological communities, invasive species can threaten human health and cause significant economic losses related to decreased productivity in croplands and interference in commerce (e.g. clogged waterways and industrial pipes) (Vitousek et al. 1996 in Mack & Lonsdale 2001). Pimental et al. (2004) estimated that the negative effects and cost of management for invasive species totals more than $120 billion/year in the U.S., a number that will surely increase as new invasive species are introduced and the geographic ranges of existing species expand.
