Analysis of optimum age and maximum increment of forest stands for developing community forests

The community forests are one of the main suppliers of wood needs in the future. They require careful attention to the wood type to be planted, preferably choosing plants that have a short cycle. The demand for wood for the community is increasing, while the supply of timber from state forests to the wood processing industry is decreasing. This research aimed to analyze the optimum age and maximum increment of community forest stands and which species were more profitable. This research was done in a community forest with tropical environmental type. This research was quantitative, calculating the maximum volume cycle and Mean Annual Increment (MAI) values in community forest stands. The results show that the maximum volume increment was found in jabon (Anthocepalus sp) stands, namely at the age of 8 years, with a total of 600 trees/ha, an average diameter of 30 cm, an average height of 13 m, a total volume of 330.64 m3/ha, and a mean annual increment (MAI) of 41.33 m3/ha/year. Jabon stands at the age of 8 years were suitable for harvest because they reached the maximum volume increment in the soil types of Hapludults Dystrudepts, Haplustepts Haplustalfs, and Endoaquepts Udifluvents
