“…Infested and non-infested areas used in this study had been so since at least 1996. Euphorbia esula is a Eurasian perennial that invades mixedgrass prairie in rangeland and natural areas throughout the northern Great Plains and causes extensive environmental and economic damage (Bangsund et al, 1996(Bangsund et al, , 1999Trammell and Butler, 1995). Aerial photography in 1991 indicated approximately 1620 ha of Euphorbia in the South Unit of TRNP, with the distribution closely aligned with watercourses and drainages.…”

“…Estimates exist, for instance, for annual control costs for the screw worm fly, Chrysomya bezziana, and a range of weeds in Australia (Anaman et al 1994, Watkinson et al 2000; the impacts of knapweed and leafy spurge on the economy of several American states (Bangsund et al 1999), and the impacts of the green crab, Carcinus maenas, on the North Pacific Ocean fisheries (Cohen et al 1995); damages to North American and European industrial plants from the zebra mussel, (Khalanski 1997); and losses in the Black Sea fishery due to the comb-jelly, Mnemiopsis leidyi (Knowler and Barbier 2000). There are also estimates of the benefits from clearing a number of alien species from Fynbos ecosystems in South Africa (Higgins et al 1997).…”

ABSTRACT. We postulate that the causes of the problem of invasive alien species are primarily economic and, as such, require economic solutions. Invasive alien species are of increasing concern for four reasons. First, introductions are increasing sharply, while mechanisms for excluding or eradicating alien species have been either withdrawn or progressively weakened. Both trends are due to the liberalization of and increase in international travel and trade, an economic phenomenon. Second, the costs of invasions are rising rapidly due partly to increasing human population density, and partly to increasing intensity of production in genetically impoverished agricultural systems. Third, biological invasions are associated with a high degree of uncertainty both because they involve novel interactions, and because invasion risks are endogenous. Actual risks depend on how people react to the possibility of invasions. Fourth, the exclusion and control of invasive species is a "weakest-link" public good. This places the well-being of society in the hands of the least effective provider. We argue that an economic solution to the problem of invasive species has two components. One is to use incentives to change human behavior so as to enhance protection against the introduction, establishment, and spread of invasive behavior. The other is to develop institutions that support the weakest members of global society, converting a "weakest-link" to a "best-shot" public good.

“…Although comprehensive economic analyses exist at a state or regional basis for leafy spurge (Euphorbia esula L.), saltcedar (Tamarix spp. ), and some knapweeds (Hirsch and Leitch 1996;Bangsund et al 1999;Zavaleta 2000), other species have not been studied. Agricultural costs, including loss of grazing value, have been quantified for some species, but environmental and societal costs are typically not included in the analyses.…”

Nonindigenous invasive weed species can have substantial negative impacts on the quantity and quality of outdoor recreational activities such as fishing, hunting, hiking, wildlife viewing, and water-based recreation. Despite the significance of impacts on recreation, very little research has been performed to estimate the corresponding economic losses at spatial scales such as regions, states, and watersheds. This is true primarily because in most jurisdictions the data necessary to estimate recreational impacts are scarce and incomplete. Because of the challenges involved in measuring recreational losses precisely, we illustrate a method that can provide indications of the ranges in which the true economic losses likely lie. To reflect underlying uncertainty in parameters such as the number of acres infested in a jurisdiction and the rate at which wildlife-related recreation decreases as a function of increasing weed infestation, we developed a range of estimates using lower, medium, and higher scenario combinations of parameter and variable values. Our case study jurisdiction is a western state (Nevada) in which nonindigenous weed infestations on public lands have expanded rapidly in recent years. Under conservative assumptions, the negative economic impacts stemming from the adverse influence of nonindigenous weeds on wildlife-related recreation in Nevada likely range from $6 million to $12 million per year. Using the most conservative findings for annual recreation losses, the predicted discounted stream of negative economic impacts over a future time horizon of 5 yr ranges from about $30 million to $40 million in Nevada, depending on actual future expansion rates of weeds.
