Natural regeneration potential of Shorea pinanga Scheff and Shorea platyclados Slooten ex Endert. in Gunung Dahu research forest, Bogor-West Java

Abstract Natural regeneration potency is important component that ensure replenished of trees as older trees are died or harvested. Natural regeneration drives the change of stand structure by time. The objectives of this research were to analyze the potential and natural regeneration of S. pinanga and S. platyclados stand, and to analyze environmental factors that affect the natural regeneration of both species in Gunung Dahu Research Forest (GDRF). Natural regeneration potantial of S. pinanga was very low, only 4 seedlings were found in 2 observation plots, while natural regeneration potential of S. platyclados was higher that had total number of 1874 seedlings observed. Environmental conditions such as slope and elevation were sufficiently support regeneration of S. platyclados at the seedling level.
