Tropical rain forest, in a minute scale of geographical distribution on earth comprises 7% of total land surface, functions as a biodiversity haven for 50% of terrestrial life. Amazingly, in 10 ha o{Borneo forest, 700,species of trees can be found which is equal to the whole species found in North America. Ecologically speaking, with the current situation of rain forest degradation, birds species for example, will experience the loss 0{25% 000million species before the year 0/20J5, which equals' to the 5() species a day. The major family in tropical rain forest, -Dipterocarpaceae, representing 40% of emergent trees and 30% of basal area in land and hill forest, where its forest management is a serious call for those who listen. This family has become the primary candidate for timber harvesting based on their strength and stability. The advent of timber harvesting with the introductionof Selective Logging became the first step of Malaysia towards' utilization of forest derivatives. Since then, many logging systems were introduced and improved towards sustainable production for the sake of economic productivity and biodiversity conservation. Rehabilitation and forest management play vital role in maintaining the resilience of this family yet the timber harvesting method should also need holistic amendments to sustain Dipteroarpaceae from its extinction and loses of important genetic diversity. This paper highlights the overview of D11Jterocarpaceae as the main logging sources by describing its reproductive physiology, regeneration, their journey amidst degradation, the improvements of timberharvesting method towards sustainable future as well as compiling the past and present researches to find the gap of knowledge, towards a core comprehension of this majestic family Dipterocarpceae.Keywords: Diptcrocarpaceae, Logging, Rehabilitation, Silvicalture,Regeneration.
