his is the most dominant forest type in the hill forest of Brunei, composing at least 41% of all forest in the country.
It is also the most uniform but the most complex forest type. The uniformity lies in itsw structure and physiognomy - a dense, multi-storied high forest with an uneven canopy.
Its complexity by its great floristic richness.
Lowland Association |
Includes mixed Dipterocarp found in the low terrain of labi Hills, Ladan Hills, Andulau Forest Forest Reserve, and Temburong forests. This type is typically low-density,
particularly on alluvial soils, through not freshwater swamp. |

Hill Forest |
This makes up the predominant forest type in the whole Brunei Darussalam. It has similar distribution as the lowland type except that the main concentrations of the
Dipterocarp are found in the hills of Labi, Ladan, Andulau, and Temburong areas. |
The highland mix is found in the high mountain ridges at Retak and Tudal, with an altitude of over 800 meters above the sea level. Tree canopy height is about 30 to 40 meters. Trees are generally medium-sized but with some large emergents occurring singly or in group.
Dipterocarp predominate the upper canopy. On the ridges, massive trees ofShorea flaviflora are frequent, and on the slopes are yellow meranti trees (mainlyShorea faguetiana ).
There are no kapurs and selangan batu trees here. Red meranti (primarilyShorea ferruginea ) trees do not attain large size. Parashorea parviflora , which is generally rare in other mixed Dipterocarp forest, is well representated here. Non-dipterocarp trees include Koompassia malaccensis , Alseodaphne bancana , and Melanorrhoea macrocarpa , which are rarely found in the mixed Dipterocarp in this group is about 1000 meters.
