Trunk diameter (D, cm) and tree height (H, m) growth curves were produced for 49 timber tree species from planted forests in West Java, Indonesia. Data were available covering a period of more than 40 years. The D and H of all trees of various ages were measured and coefficients of the Gompertz growth function were determined for each tree species. The tree species were then classified according to their wood production potential, on the basis of the relationship between their potential growth rate k, and asymptotic maximum carrying capacity A. The relationships between k and A, for both D and H growth curves of the tree species investigated, were negatively correlated (p < 0.05). Tree species of the Dipterocarpaceae exhibited a variety of growth characteristics with respect to D. In contrast the H growth characteristics for this family tended to be similar, with lower k values and higher A values than other tree species. These growth performance data for specific timber tree species will be useful to aid in the selection of tree species to plant, and in facilitating the establishment of forestry systems with long-term rotations (30 to 50 years) in the humid tropics.
