Abstract
Tropical rain forest in Indonesia is increasingly degraded at the rate estimated at about 2 millions hectare per year. The Government of Indonesia has placed much emphasis on the reforestation of degraded forest. The target is to establish commercial plantation and this could be considered as one of the national priorities. In the long term future supplies of forest products will increasingly come from commercial plantations and commercial forest plantation will help Indonesia to relive pressure on and save the remaining natural forests. The ideal commercial forest plantation is to place the right species in the right site with the right growing space at each state of development. Twenty potential dipterocarp species were screened and tested in five replications by using randomized cComplete block design at test plantation. Preliminary findings indicated that the growth rate of the tested dipterocarps species could be grouped into slow medium and fast. Four out of 20 species tested in PT. Sari Bumi Kusuma Forest Company had the fastest growth rate. At twoyear-old the heights of these species are Shorea leprosula (4.64 m) Shorea parvifolia (4.58 m) Shorea platyclados (4.47 m) and Shorea johoriensis (4.10 m). These four species are now become the target species for commercial plantation in Indonesia especially in Sumatra and Kalimantan. The species with medium growth rate are Shorea artinervosa (3.50 m) Shorea smithiana (3.16 m) Shorea stenoptera (3.59 m) and Hopea grifitii (2.85 m). Those with the slowest growth rate are Dipterocarpus caudiferus (1.94 m) and Vatica oblongifolia (1.83 m).
