Sustainable-yield model and displayed the results as a table you can inspect. Key assumptions I used:
• Harvest cycle = 5 years (so ~20% of the eligible pool is harvested each year).
• Retain 15% of trees permanently for resilience/genetic diversity.
• Annual mortality = 5% (compounded over the 5-year cycle → ~22.6% cumulative loss).
• Oil yield = 2.5 ml per kg chips (average).
• Scenarios: planting densities 400 / 800 / 1000 trees/ha; chip yields 200 / 350 / 500 g/tree.
Summary of outputs shown (examples pulled from the table):
- At 800 trees/ha and 350 g/tree, eligible pool ≈ 499 trees → ~100 trees harvested/yr → ~34.9 kg chips/ha/yr → ~87.3 ml oil/ha/yr.
- At 1000 trees/ha and 500 g/tree, eligible pool ≈ 624 trees → ~125 trees harvested/yr → ~62.4 kg chips/ha/yr → ~156 ml oil/ha/yr.
