ABSTRACT: Optimal ways of management forward eelgrass beds areas are different in each area, because of their ecosystem and their culture. So, it is important to take the difference of the property in each eelgrass beds into account when we manage eelgrass beds and coastal town around eelgrass area. We investigated the structure of the interests around eelgrass beds areas in Notoro Lake and Osakikamishima Island in Hiroshima as typical objections to compare their structures. Each ecosystem services have regional difference, and there are some competitive relationship with other stakeholders in both of two areas. Many stakeholders used food supply service of the eelgrass beds in Notoro Lake area, and there are many stakeholders using various services of eelgrass beds in Osakikamishima Island area. In addition, there are weak conflicts between stakeholders in Notoro Lake, because of the strong management regime by fisher mainly for fisheries resource conservation (spawning/nursery ground, sheltering). On the other hand, there are relatively strong conflicts between stakeholders in Osakikamishima Island because of its weak management regime. We concluded the optimal ways of management forward eelgrass beds are different between north and south area.
