This study aimed to measure the growth performance of Shorea macrophylla trees that were planted in 2012 by line planting method at Gunung Apeng Forest Reserve Sarawak. This species is well-known for its valuable timber, major source of illipe nuts and other benefits that had been discovered yet. However, S. macrophylla had listed under IUCN Red List as a threaten species. The objectives of the study were i) to determine the best requirement of light intensity for S. macrophylla to grow well, ii) to determine effect growth or survival percentage of S. macrophylla under different treatments and, iii) to evaluate the potential of commercial species in the study area. S. macrophylla planted under line planting method with 100 m length and 50 m width with three different silvicultural treatments which are control, line slashing and line slashing with tree girdling. Each treatment has two subplots and every subplots have 30 trees. Each tree was measured its diameter at 30 cm above ground, tree total height and light intensity under each tree. The results indicated that the line slashing treatment has the highest survival percentage, diameter and tree total height among these three treatments. Apart from that, all potential commercial species within study plot was enumerated and crown layout is determines to indicate the light intensity percentage in the study plot. It was shown that Alstonia scholaris is most dominant species and Treatment 2 (line slashing and girdling) has highest percentage of area covered by commercial plant’s crown.
