Abstract

Dipterocarp species are the mainstay of forest products in the form of carpentry wood. Preserving the Dipterocarpaceae species of Dipterocarp Forest Plantation is important. This study aims to determine the percentage of optimal canopy cover for the growth of D. lanceolata. Furthermore, primary data were obtained by measuring and observing the growth of D. lanceolata in the form of diameter at breast height, tree height, the percentage of canopy, and environmental conditions (temperature and humidity). Meanwhile, secondary data, which was in the form of initial growth data when D. lanceolata, was newly planted and the general condition of the study site. The relationship between the percentage of canopy cover and growth in diameter and height of D. lanceolata aged 5 years growing in KHDTK Haurbentes has a significant effect but it has a low correlation. In addition, D. lanceolata can grow in the canopy cover percentage range of 40% - 65%.
