Abstract

Probable ages for trees in tropical semi-evergreen rain forest at Sakaerat was determined from annual or a 2-years period increment of selected trees. Increment of selected trees were determined by using dendrometer, a venier growth measuring band. Eighteen species were studied. Trees species in the upper canopy grew faster than tree species in the middle canopy and lower canopy layer. Upper canopy species, eg. Shorea henryana, Pakia sumatrana, Homalium sp. and Dialium cochinchinensis, reached 30 cm dbh at aged 78 - 144 years. Hopea ferrea was an only upper canopy species which grew slower than the others. It took 265 years to reach 30 cm dbh. The middle canopy and the lower canopy layer species, eg. Aglaia pirifera, Walsura trichostemon, Memecylon spp., and Hydnocarpus castaneus, reached 30 cm dbh at aged 165 - 453 years.
