Part of the Ecological Studies book series (ECOLSTUD, volume 140)


The coastal area of East Kalimantan, where the Bukit Soeharto Education Forest (BSEF) of Mulawarman University is situated, has a tropical rainforest climate and is known to be drier than the other parts of the island of Borneo (Whitmore 1984, Mackinnon et al. 1996, Walsh 1996b). The description of the climate in East Kalimantan is mainly based on the rainfall data recorded at several meteorological stations and there is little published information about climatic characteristics for East Kalimantan other than rainfall. In this chapter, we present some climatic characteristics, such as rainfall, solar radiation, air temperature and air humidity in the BSEF. Our data includes severe drought periods related to a pronounced El Niño Southern-Oscillation (ENSO) event in 1997–98.
