Effect of different silviculture treatments on growth performance of Kapur Bukit (Dryobalanops beccarii) at Gunung Apeng Forest Reserve, Sarawak

A study on the effect of different silviculture treatments towards 10, 9, 8 and 7 years-old of Kapur Bukit (Dryobalanops beccarii Dyer, J. Bot) was planted as enrichment planting in Gunung Apeng Forest Reserve, Sarawak. Silvicultre treatments that have been applied to the plots were (i) line slashin...
