A study was conducted within Bam River catchment in Danum Valley, Lahad Datu. The purpose of this study is to estimate throughfall and interception value in Baru River catchment area. This research also studied the effect of nearest canopy height and canopy density of two individual tree species (Shorea parvifolia and Koompasia excelsa). Throughfall measurement was carried out from 14 August to 14 December 2008 using 40 Personal designed storage gauges. Throughfall was quantified as 66.5% from the gross rainfall during three months study. The estimated interception loss was 32.1 % at the gross rainfall which is higher than the previous study. The high interception loss due to low throughfall may have resulted from the spatial variability of rainfall in Baru catchment and Danum Valley Field centre (DVFC). The weak relationship between canopy density and interception loss indicates tendency of canopy density to influence the interception loss but canopy architecture, on the other hand play more important role in the interception process. Meanwhile the height of nearest canopy does not correlate significantly with interception loss (R2= 0.00 I).
