摘要：
A model was developed to estimate the stable timber output from shade stands of Cordia alliodora in coffee farms. The model predicts, for stand densities between 120-290 trees/ ha, timber yields of 9-24 and 6-15 m3/ha/yr of total and commercial overbark volumes, respectively. Current harvest rates in four sample farms are below these figures. The model is used to describe the transient trajectory (in terms of timber output over time) of Cordia alliodora stands with different initial DBH distributions. Practical recommendations are derived as to how farmers should manage their trees to achieve stable timber outputs in the shortest time possible. © 1990 Kluwer Academic Publishers.
