The permissible harvesting quota depends on the total number of trees, which are assessed per species and allotment. A minimum of 20 percent of trees, which could have been harvested, are left standing to ensure seed production; the same happens with trees along waterways and those with limited accessibility.

The harvest teams always operate in the forest according to detailed instructions, which are prescribing every step in the process. If a specific tree turns out to be not usable during harvest time, it won’t be felled. This is why Precious Woods only harvests a maximum of 15 to 20 cubic metres logs per hectare during the first harvest cycle of 25 years, even though the monitored tree growth would allow a maximum of 40 cubic metres.

For quality reasons only the most valuable trees with a large diameter are harvested.
