Introduction
Back in September 1990, the restoration and rehabilitation of degraded tropical forest were my specific interest. What to plant and how to plant were the main questions when dealing with restoration and rehabilitation of degraded forest. So that why the phytosociology, actual and potential natural vegetation were used as a basic in this early stage of species selection.

Sprouting ability is highly variable among different tree species. In many cases, there are trade-offs in carbon allocations between growth and storage in seedlings. However, this trade-off is likely to change with growth stages from seedling to mature plant because carbon investments in reproductive activities and/or risk of disturbance also chang...
