Ecosystem services are the specific results of ecosystem processes that either directly sustain or enhance human life (as does natural protection from the sun's harmful ultraviolet rays) or maintain the quality of ecosystem goods (as water purification maintains the quality of streamflow).

As agriculture faces documented decline in bees and other insect pollinators, empirical assessments of potential economic losses are critical for contextualizing the impacts of this decline and for prioritizing research needs. For the state of Georgia, we show that the annual economic value of biotic pollinators is substantial--US$367 million, equivalent to(More)
or programs, such as watershed ecosystem restoration, are designed to improve multiple ecosystem services and consist of multiple components or parts. The valuation of such policies or programs should address the multi-dimensionality of the problem. A hybrid of the contingent valuation method (CVM) and attribute-based analysis (Holmes and Adamowicz 2003) is(More)
