T
F
It is always necessary to pre-clean the GROT harvesting site.
T
F
When estimating the available GROT volume in relation to the volume of harvested roundwood products (often used in southern Sweden), there is a rule of thumb according to which the available GROT volume is about twice the volume of harvested roundwood products.
T
F
All people involved in a harvesting project, i. e. the planner, harvester operator, forwarder operator, and trucker, should find "the golden mean" and a way how to contribute to the best possible overall economic result.
