Forest is known as a provider of ecosystem services which can be benefit to the community surrounding it. Protected areas are support system for human livelihood adjacent to them. In addition to providing ecosystem services such as hydrology and local climate, park boundary forest provided biodiversity ecosystem services such as pollination and seed dispersal which will maintain sustainable agricultural crop harvesting while preserving the integrity of forest edge at park boundary.

Megaerops ecaudatus.

The study will be carried out in Bukit Barisan Selatan National Park, in the Province of Lampung, Sumatra, Indonesia which is surrounded by human settlements and agriculture lands and thus, threatened by continuous deforestation and encroachment. The work will provide information on the status of the bird and bat community which serve as pollinating agents and seed disperser in Bukit Barisan Selatan National Park. In more detail, the data will reveal the community structure of birds and bats which use the habitat at the park boundary, edge effect, and how they affect the vegetation structure around the edge. Research will be carried out along forest edge, particularly birds and bats, as well as trees dispersed or pollinated by birds and bats along forest edge. We will select at least three sites and set up monitoring plots (transects) along the forest edge of Bukit Barisan Selatan National Park. The plots will be on the ecotone between forest edge and other ecosystem type such as agricultural fields.

The result of this work will be used to approach the community around the park on the importance of protecting biodiversity of the national park while also receiving benefits from it. Local community particularly school children can understand the function of the forest adjacent to them and its biodiversity. When biodiversity protected, the local community adjacent will also gain benefit through the increase of fruits and agricultural crops. Therefore, the information on these services will be the base for combating the deforestation.
