title: Survival and growth rate of several climax species of tree in tropical rains forest Ulu Gadut West Sumatra Indonesia.
abstract: Long-term study of the growth of a forest stand is needed in order to conserve tropical forests. We have been monitoring the survival and growth of six species of climax (Cleistanthus glandulosus, Hopea dryobalanoides, Mastixia trichotoma, Microcos florida, Nephelium juglandifolium and Swintonia schwenkii) in Ulu Gadut tropical rain forest, West Sumatra, 32-year period (1981-2013). The average of Relative Diameter Growth Rate (RDGR) for six species ranged from 000 1-0028 cm year(-1) with a survival rate of 46.15-86.67%. There was a significant difference in the growth of each species (f = 2,613; p < 0.05, Scheffe post-hoc test). Growth of Trichotoma mastixia and Microcos florida were faster than other species. This indicated that the second species was the determinant of the sustainability of tropical rain forests in Ulu Gadut in the future.
