This article explores transnational ecosystem services in North America, provided by winter habitat for waterfowl in western Mexico coastal lagoons, and the hunting industry supported by these birds in the United States. This article shows that the number of waterfowl harvested in the United States is related to the abundance of waterfowl wintering in Mexico. On average, this flow of ecosystem services annually yields US$ 4.68 million in hunting stamp sales in the western United States. A demand curve, fitted to duck hunting licenses as a function of stamp price and previous-year waterfowl harvest, estimated US$3–6 million in consumer surplus produced in addition to governmental stamp sales revenue. This strongly suggests that waterfowl wintering habitat in western Mexico is economically valuable to U.S. hunters. Because hunters may benefit substantially from these habitats they may be willing to pay for conservation efforts in western Mexico that can result in transnational benefits received in the United States.

The results of a seven-year study of the herbaceous plant communities of five created wetlands constructed at Fort Drum, New York is presented. It details the methods used in constructing the wetlands such as an analysis of hydrology and soils; the use of cover plants including redtop (Agrostis gigantea), creeping foxtail (Alopecurus arundinaceus), and perennial ryegrass (Lolium perenne); and the use of a wetland seed bank which included 23 species of wetland plants. The evolution of plant diversity in the constructed wetlands is detailed.
