Outline of Final Research Achievements

We assessed socio-ecological aspects of ecosystem services with special reference to biodiversity in a forest-agricultural landscape in West Java, Indonesia, with the aim of identifying suitable landscape management practices for ensuring the delivery of multiple ecosystem services. The results show that both local people's perceptions of ecosystem services and the functional biodiversity of birds and insect pollinators generally decreased from the remnant forest to human-modified ecosystems. Among the human- modified ecosystems, mixed-tree agroforests exhibited the highest biodiversity and were perceived as sources of various ecosystem services. Therefore, to conserve the diversity of birds and pollinators as well as to preserve services, protection of forests should be a priority. Moreover, the expansion of agroforests in buffer zones around the forest could reduce human pressure on the remnant forest while enhancing biodiversity by establishing them close to the remnant forest.
