6. Super rich biodiversity
About three-fifths of the country is covered with virgin tropical rainforest and another one-fifth is under secondary forest.
The undisturbed rainforest consists mainly of hardwoods of the Dipterocarpaceae family.
most of which are of commercial value.
Large expanses of freshwater and peat swamps are found in the poorly drained lowlands of the Belait and Tutong rivers,
while mangrove swamps are common along the lower riverine reaches and sheltered coastal areas.
The complex vegetation of the rainforest provides niches for a rich variety of animals, including proboscis monkeys, leaf monkeys, pigtail macaques, gibbons, sun bears, sambar deer, pangolins, bats, and many other mammals.
Among Brunei’s most notable birds are its argus pheasants and hornbills.
Numerous species of reptiles, including the large reticulated python, inhabit the country’s swamps and woodlands.
