Importance of topography and soil physical properties on the growth of shorea macrophylla under reforestation at Sampadi Forest Reserve

Shorea macrophylla are characterised as one of the Dipterocarp indigenous trees that exhibit a fast growing ability. This species is said to be favourable on clay riparian alluvium and locally abundant on damp soil on hillside by river and streams habitat. Several studies reported that S. macrophy...

Study plots with the size of 50 m x 50 m were constructed at reforestation areas planted with S. macrophylla at various age stands from 1996 (SM96), 1997 (SM97) and 1998 (SM98).

The findings showed that in relation between soil physical properties and topographical characteristics, S. macrophylla shows strong adaptability across all range of elevation and other soil physical properties. However, the presence of stagnant water and interruption of pioneer species in between the planting lines greatly resulted in poor growth performance and survivability of S. macrophylla.
