Type | Parameter | Default value | Short description |
|---|---|---|---|
Diameter limits | Harvesting diameter | 52.5 cm | Lower limit for target trees harvesting, upper limit for thinning |
Thinning diameter | 27.5 cm | Lower limit for aggregates harvesting, thinning, and dead trees harvesting | |
Cutting quantities | Minimum quantity to cut | 4 m2/ha | Lower basal area to cut (profitability limit) |
Standard quantity to cut | 6 m2/ha | Standard basal area to cut (mean increment) | |
Maximum quantity to cut | 8 m2/ha | Upper basal area to cut (for destocking) | |
Cuttings proportions | Harvesting proportion | 33 % | Maximum ratio of basal area to cut, over total basal area designed for harvesting operation |
Thinning proportion | 10 % | Maximum ratio of basal area to cut, over total basal area designed for thinning operation | |
Probability weightings | Species proportion power | 0 | Probability weighting power for species proportion |
Local density power | 10 | Probability weighting power for local density | |
Spatialization | Aggregation area | 0 m2 | Maximum cutting aggregation area for harvesting operation |
Buffer distance | 5 m | Minimum distance between 2 cut trees | |
Biodiversity conservation | Minimum species proportion | 0 % | Threshold to allow cut of the species, in % of total basal area |
Large trees preserved | 0 | Number of large trees preserved for biodiversity | |
Dead trees harvesting proportion | 0 % | Maximum proportion of dead trees allowed to be harvested, over total fresh dead wood basal area |
