| Sumario: | This report is a thesis work for a B.Sc. in Forestry exam at the 5028,
SLU. The work was an assignment from Sydved and the aim of the work was to investigate the economical output of removing understorey trees before first thinning.
Four treatments were studied.
- no cleaning before thinning
- cleaning of all trees less than DBH 5 cm before thinning
- cleaning of all trees less than DBH 7 cm before thinning
- cleaning of all trees less then DBH 9 cm before thinning
The result shows a decrease of the cost per m3 for the harvester with about 38% if all trees less than DBH 9 cm was cleaned before thinning compared with the un-cleaned area. At the same time the total net revenue increases with about 22%. |
