| Abstract | Reliable data on the growth and yield of logged-over forest to determine sustainable cutting cycles are widely missing for the tropics.We used the process-based model FORMIND2.0 to analyse the growth and yield of logged-over forest in Venezuela under different logging scenarios over a period of 240 years and compared results with unlogged stands. The performance of the model was evaluated with a detailed stability and sensitivity analysis.In the absence of further logging, the logged-over stand approached the stand structure of mature forest in terms of bole volume and basal area after about 50-100 years.Thirty-year cutting cycles with conventional logging methods and net extraction volumes of 45 and 60 m3ha-1cycle-1 did not provide sustainable yields under either of two minimum felling diameters (35 or 50 cm) that were applied. Only the 60-year cutting cycle provided sustainable yields under conventional and reduced-impact logging with the different minimum felling diameters and a range of net volumes extracted (30-60 m. 3ha-1cycle-1 With the longest cutting cycle (60 years), bole volume recovered to levels similar to the mature unlogged stand, but the species composition was very different.Scenarios with reduced-impact logging provided a significantly higher timber volume than under conventional logging. The conservation of forest resources will only be possible with long cutting cycles (at least 60 years) in combination with reduced-impact logging. |
