Dipterocarp forests in Southeast Asia exhibit unique reproductive phenology known as general flowering (GF).This forest is known for the supra-annual synchronization of flowering among diverse plant taxa. Prolonged drought and low temperature have been suggested as the trigger of this phenomenon, but the debate continues because information on the relationship between spatiotemporal patterns of GF and climatic conditions is surprisingly limited. To address the challenge, we used MODIS from a set of Terra satellite data, to estimate climatic and vegetation variables;fPAR, GPP, LST and TA; examining relationship between these variables and GF magnitude of 81 forests in the Peninsular Malaysia over 10 years.Our preliminary study found that high values of fPAR and inexistence of fire were observed before large-scale GF in 2001, 2002, 2005 and 2010 but not before minor-scale GF in other years. However, no distinct differences in LST and GPP were observed between large-scale and minor-scale GF suggesting that fPAR and TA are possible indicators to predict GF using remote sensing application.
