一般講演（ポスター発表） P1-104A (Poster presentation)
Peat swamp forest is one of the most unique ecosystems in Southeast Asia. While bird species diversity is considered to be low, peat swamp forests are becoming refuges for lowland forest birds, which are under great pressures from logging, hunting and development. However, the forest is now explored by local people and large-scale pulpwood (acacia) plantation. In this study, we aim to clarify the differences in bird community composition among different land use systems in peat land, including natural peat-swamp forest, planted pulpwood (acacia) forest, rubber jungle, and residential area (mostly home garden). Our study site is located in Bukit Batu district, the northern part of Giam Siak Kecil-Bukit Batu Biosphere Reserve in Riau, Indonesia. Point count was done along 1km transect in each land use. We observed 47, 15, 34, and 43 species in natural forest, planted acacia forest, rubber jungle, and residential area, respectively. Bird diversity was the highest in natural forest, and rubber jungle and residential area have the moderate level of diversity, while planted acacia forest has the lowest diversity. Community composition in natural forest was significantly different from other land uses, which means that natural forest has irreplaceable value for bird diversity conservation.
