Diameter growth of acacia mangium willd. in planted forest zone, Bintulu

Acacia mangium Willd. is one of the fast-growing species that can tolerant very well of varied site conditions. It has been chosen for forest plantation in Malaysia including Sabah and Sarawak. The objective of the research is to detennine the growth rate of A. mangium in Planted Forest Zone in Bintulu in tenns of diameter and height different ages as well as the mean annual increment (MAl). Data collected include diameter and height for various ages. Data analysis will also be done where the best fonnula will be used to calculate the diameter and height of the trees. The results expected in this research are the data on diameter and height as well as fonnula to be used to describe the growth rate ofA. mangium
