Applies when Thinning Algorithm = Hugin.
- Deciduous/Conifers (x1)
- Parameter for adjusting thinning grade of deciduous trees versus conifers.
- x1 = 0: Same proportion.
- x1 > 0: Thinning grade for deciduous trees is relatively larger than thinning grade for conifers.
- x1 < 0: Thinning grade for conifers is larger than for deciduous.
- Range: between -1 and 1.
- Default: 0
- Spruce/Pine (x2)
- Parameter for adjusting thinning grade of spruce trees versus pine (including contorta).
- x2 = 0: Same proportion.
- x2 > 0: Thinning grade for spruce is larger than for pine.
- x2 < 0: Thinning grade for pine is larger than for spruce.
- Range: between -1 and 1.
- Default: 0
- From above/below (x3)
- Parameter for thinning form.
- x3 = 0: Uniform thinning.
- x3 > 0: Thinning from above.
- x3 < 0: Thinning from below.
- Range: between -1 and 1.
- Default: -0.2 (i.e. from below)
- Second smallest/smallest (x4)
- Parameter for distributing thinning grade over two smallest diameter classes, in each thinning species group (spruce, pine, deciduous).
- x4 = 0: For each species group, Same proportion in diameter class 1 and 2.
- x4 > 0: Higher thinning grade in diameter class 2 than in diameter class 1.
- x4 < 0: Higher thinning grade in diameter class 1 than in diameter class 2.
- Range: between -1 and 1.
- Default: -0.1 (i.e. relatively more of smallest)
- Largest/Second largest (x5)
- Parameter for distributing thinning grade over two largest diameter classes.
- x4 = 0: Uniform thinning.
- x4 > 0: Thin more of largest trees.
- x4 < 0: Thin more of second largest than of largest trees.
- Range: between -1 and 1.
- Default: -0.1 (i.e. relatively more of second largest)
