Population justification: The population is estimated to number 150 individuals in Malaysia (Yeap Chin Aik in litt. 2002), and up to 250 individuals in Indonesia (M. Silvius in litt. 2002), totalling fewer than 500 individuals in total (Y. Noor Rusila in litt. 2002). The population size is likely to lie between 400-500 individuals, roughly equating to 260-330 mature individuals.
Trend justification: This species's population is suspected to have decreased very rapidly, in line with levels of forest loss and fragmentation, owing primarily to logging and conversion to oil-palm plantations.
