Research Abstract

This research was organized to establish the monitoring systems and stations in tropical rainforest ecosystems, to contribute to a core-research program "Global change impact on terrestrial ecosystems in Monsoon Asia "(TEMA) of IGBP-GCTE.TEMA monitoring network across East-Asian forest belt is accomplished by the establishment of lowland tropical rainforest sites in Borneo Island. This research was carried out under the collaboration with Indonesian and Malaysian counterparts' full support.
One site in Central Kalimantan, Indonesian Borneo, was characterized by regionally nutrient poor systems, i.e.heath forest and peat-swamp forest. We established four permanent plots and one research hut on these ecosystems in Lahei site, 20-km NE from PalangkaRaya, where we carried out tree census and set litter traps and litter bags. Monitoring of the emission of greenhouse gasses was regularly carried out. To examine a lager-area characteristics of terrestrial ecosystems, preliminary land water survey was also conducted.
For coastal ecosystems, research station was established in Tabin National Park in Sabah, Malaysian Borneo, and high-altitude forest systems were monitored in Mount Kinabalu National Park in Sabah.
One symposium held in Sapporo early in February covered present activities in relation to TEMA,and four members participated in the GCTE-LUCC Conference in Barcelona in mid March, reporting the present activities.
