Abstract:

<p>Optimal treatment schedules are presented for even-aged Shorea robusta stands using varying management objectives. The objective variables used were total wood production (WP), commercial timber production (CTP), sawlog production (SLP), forest rent (FR) and soil expectation value (SEV). A simulation- optimization system was developed based on a spatial yield model. The non-linear method of Hooke and Jeeves was used to solve the optimization problems. The treatment schedules were optimized with zero, 1 and 2 thinnings per rotation. Results on 2 dense 5- yr-old stands are presented. Irrespective of the management objective, the first thinning was conducted immediately in both the stands. When wood production was maximized the rotation length was short: 6 and 24 yr. Treatment schedules for maximal CTP and SEV were relatively similar: the rotation lengths for maximal CTP were 23 and 41 yr and for SEV 19 and 51 yr for the 2 stands, respectively. Maximizing SLP or FR required heavy thinnings and a long rotation: 57 and 85 yr for SLP and 52 and 87 yr for FR. The mean annual increments of the optimal treatment schedules were 8.5-25.1 m³ ha^-1 for total wood production, 6.5-12.1 m³ ha^-1 for commercial timber production, and 4.8-7.6 m³ ha^{- 1} for sawlogs.</p>
