Relationships between diameter at breath height and total height of trees in Kaeng Krachan forest complex, Thailand

Abstract

The study aims to find the correlation between the tree diameter at breast height (DBH) and total height. This equation is useful for estimating both tree height in forest inventory and tree diameter in carbon sequestration assessments. Secondary data from 4 sites in permanent sample plots in Kaeng Krachan Forest Complex were utilized to conduct this research. The data were collected by the Phetchaburi National Parks Research Center, using reliable tools to measure tree diameter and height. The results show that there is a logarithmic correlation between diameter and height of trees. The values of the equation constant as well as the relationship level of the equations are specific for each tree species.
