Abstract

This report covers some of the work done on the mechanised harvesting of young oak stands for the production of whole tree chips as a bioenergy feedstock. Two thinning methods, a double row thinning and a combined single row and selection thinning were tested. Results showed overall production costs of roughly 7 € GJ-1 delivered into containers at roadside, with a difference of about 1 € GJ-1 between the two methods. As the production cost equated to the maximum delivered sales price, the mobilization of this feedstock would need to be incentivized.

Abstract

A trial combining a 7th row and selective thinning was conducted in a young spruce stand. The small trees resulted in a high unit volume price, but the cost is somewhat offset by the saving of relocating both harvester and chipper twice. Results showed that it was possible to carry out the early thinning at no net cost to the forest owner.
