Tapang Tree in Semban Village,Sarawak.

The Koompassia excelsa tree is among the tallest trees in the world, and also one of the most prominent trees in the tropical rainforests of the Sunda Shelf. It is found in Sumatra, Borneo, South Thailand, and Peninsular Malaysia. The grey, whitish bark of the tree, large bole, and often handsome crown makes it stand out amongst the other trees (usually). It is known by different names in different regions – Mengaris in Brunei and Sabah, Tualang in Peninsular Malaysia, Sialang in Indonesia, and Tapang in Sarawak. The name tualang comes from the Malay words of tua – old, and helang – eagle. More info The Tualang Tree or Koompassia Excelsa
The tapang tree is a revered tree for the indigenous people of Sarawak. There is a taboo in Sarawak against cutting down the tapang treee. Only naturally felled tapang trees (usually by an unusal storm or a  landside which might be natural or even unnatural) can be used. Furthermore Ibans do not cut their tapang tree in their temuda (farm) because it is a valueable source of honey and a home for the Great Kenyalang or Hornbill. Hornbills on the other hand control the snake population in Sarawak and Borneo. Without the hornbills our habitat may become dangerous actually...(sources from Sarawakiana@2)..Thank You credit to Sarawakiana@2 & Jungle Dairy.
