Wetland protection in the Upper South East (USE) of South Australia yields a range of private and social benefits. The profit motivation for private wetland owners to supply private benefits is clear whilst the provision of purely social benefits by private suppliers has no similar incentive. One potential for the provision of social benefits from private lands arises when a private benefit is jointly supplied with a social benefit. Such is the case of nature-based recreation activities such as duck hunting. In this paper, the results of a study investigating the extent of the benefits enjoyed by duck hunters in the USE are reported. The travel cost method was employed in a survey of those participating in a weekend duck hunt. The extent of the private recreation benefits so estimated is assessed in terms of their potential to stimulate the provision of wetlands for both private and social benefits.
