The strongest and most extensive mast fruiting for decades is currently underway in Sabah – and indeed over large parts of Borneo – involving numerous dipterocarp and other canopy species. Seeds of some dipterocarp species (Parashorea spp. and Dryobalanops spp. in particular) are already falling – with seed fall among trees in central Sabah (in and around Maliau Basin and Imbak Canyon) slightly in advance of those in the east at Danum and its surroundings. Unusually in the immediate period after a masting event, the weather has been extremely dry – which appears to be impacting both seed maturation and synchronicity of seed fall (and will likely affect germination and survival).
SEARRP’s Assistant Director, Dr Mikey O’Brien, is currently in the field collecting seed – so please email him if you would like further information:
