The tree species in the Dipterocarpaceae family dominate many tropical forest formations in Southeast Asia (see Figure 1). The Philippines is home to more than 50 dipterocarp tree species, of which 25 cannot be found anywhere else on Earth. About 97% of the Philippines' tropical forest have been subjected to logging activities, and are often converted to other land uses such as for agriculture. Hence, many of these important and unique tree species are under severe threat. Apart from this, climate change may further threaten the survival of these tree species as environmental conditions become increasingly inhospitable, driving potential shifts in their population ranges.
