Abstract : A small fraction of the species that inhabit the nation's fresh waters become aquatic nuisance species (ANS) when they significantly degrade services provided by water resources. Government agencies, utilities, and other water resource managers incur substantial costs controlling ANS and repairing damage to restore service performance to desired levels. National costs of and benefits from ANS management appear to be increasing, but neither is particularly well documented (e.g., Lovell and Stone (2005)). Meanwhile, competition for federal funding continues to grow and to require ever stronger evidence of net benefit from management measures in order to justify program budgets in the annual ANS management cycle (Figure 1).
