Based on their water quality, the ponds located in the Wakasakanai Sand Dune forest were classified into three categories, i. e., ponds adjacent to farmlands, ponds adjacent to road, and intact ponds. Eutrophic status and the degree of drying up of the ponds were indicated by the zooplankton and zoobenthos communities. A questionnaire survey on the attitudes of local residents in the middle reaches of a river in Kalimantan, Indonesia revealed that they use well water for daily use but utilize surface water for transportation and fishing grounds. Although they are well aware of the benefit of ecosystem services, the ongoing increase in the population after the road improvement in this area will cause problems concerning conservation of wetland environment.
