Abstract

A plantation covering 200 ha has been established to restore the biodiversity on denuded area in the Cat Tien National Park. Two models of plantation have been developed from a mixed composition of 25 local species of which seven are from the Dipterocarpaceae family. Preliminary results show a high mortality rate during the first two years and over for some species. This mortality is partly due to the hydromorphic condition of soil. Under these conditions, it appears that Dipterocarpus alatus, Hopea odorata, Lagerstroemia calyculata and Lagerstroemia speciosa are more resistant and Shorea siamensis non adaptable. Meanwhile, the mortality is also due to the initial conditions of establishment. Under sunshine, Shorea roxburghii, Anisoptera costata and species of Fabaceae family have difficulty to survive. Reforestation of Dipterocarpaceae forest on denuded area is difficult to achieve. Beside these results, Dipterocarpus alatus and Hopea odorata exhibited good growth performances from 2 to 8 years after planting.
