摘要：Little is known about the variability of ecosystem service values at spatial scales most relevantto local decision makers. Competing definitions of ecosystem services, the paucity of ecological andeconomic information, and the lack of standardization in methodology are major obstacles to applying theecosystem-services approach at the estuary scale. We present a standardized method that combines habitatmaps and habitat–faunal associations to estimate ecosystem service values for recreational and commercialfisheries in estuaries. Three case studies in estuaries on the U.S. west coast (Yaquina Bay, Oregon), eastcoast (Lagoon Pond, Massachusetts), and the Gulf of Mexico (Weeks Bay, Alabama) are presented toillustrate our method's rigor and limitations using available data. The resulting spatially explicit maps offisheries ecosystem service values show within and between estuary variations in the value of estuarinehabitat types that can be used to make better informed resource-management decisions
