Abstract

This study is to analyze the relationship between diameter at breast height ( dbh), height, and volume of standing Shorea dasyphlla, Shorea parvifolia, Shorea ovata, and Shorea leprosula tree species. The study was conducted at Phase 1, UPM -IlSE joint rehabilitation project, Bukit Nyabau Forest where the measurement was taken from different tree species. There were three stages involved in this research; first stage was building a one sampling plot in the Phase 1. Then second stage was the measurement and data collection within each plot. Fifteen standing trees in each species were randomly measured the diameter at breast height ( dbh) for all the species. All the collected data have calculated to find basal area of each tree in meter square (m2) and volume sectionals in meter cubic (m3). The volume was calculated using the Smalian's formula to find the taper volume of Shorea dasyphlla, Shorea parvifolia, Shorea ovata, and Shorea leprosula. Regression analysis was conducted to find the regression equation which could explain the relationship between volume, diameter, and height of the tree. Result showed that there has been a relationship between the volume diameter and height of a tree. By using the regression equation we could find the whole volume of a tree by only measure a dbh on the ground.
