A planting trial of indigenous timber species on degraded land was carried out in September, 1995 in Compartment 121 of Pasoh Forest Reserve, Negeri Sembilan. Open planting technique with a planting distance of 2m x 2m was employed in this study involving ten indigenous timber species, namely, Azadirachta excelsa, Cinnamomum iners, Dryobalanops aromatic, Hopea pubescens, Intsia palembanica, Neobalanocarpus heimii, Shorea acuminata, Shorea bracteolata, Shorea leprosula and Shorea parvifolia. In this study, species survival and initial growth performance were monitored and evaluated. Preliminary results at six months after planting showed that the survival of the species planted have been encouraging, ranging between 60.7 per cent - 95.6 per cent. The most outstanding species identified with high survival rates were C. iners, A. excelsa, I. palembanica, H. pubescens and N. heimii. The highest rate was exhibited by C. iners while the lowest was recorded for D. aromatica. The results of the study indicate that the most promising growth performance were shown by A. excelsa, S. leprosula, C. iners, H. Pubescens and S. parvifolia with the basal diameter (BD) increment and total height increment (HT) exceeding 3.0 mm and 20.0 cm, respectively.
