forest resource in
most European countries, with a strong
potential in contributing to building up a sustainable forest
pre-commercial thinning, which primarily creates cost but
no income because the felled trees are left on the ground. The
main reason behind why the SDS potential in Europe is
largely unexploited is the low harvesting productivity and
high operating costs, together with a low current market price
for small diameter wood. Even though there are some
commercial products designed for multi-tree harvesting of small
trees, as well as combined harvesting and chipping of small
trees on the market, research clearly shows that there is a strong
need for a development of these techniques, as well as for the
associated work methods and procurement systems, in order
to provide a feasible production chain. If more efficient
harvesting techniques and systems could be developed, the
potential SDS volume to harvest would lie in the range of 20-30
million m3 per year only in Sweden and Finland.

forest owners, forest contractors, Forest practitioners, general public
- Conventional thinning stands with small diameter trees.
- Traditional coppice stands.
- Areas for forest fire prevention with small trees or bushes.
- Linear cleaning areas like roadsides, power line corridors and strips just outside agricultural farm land.
- Improve the techniques and work methods up to the level where a profitable business can be built on SDS management and utilization.
- Develop strategies for SDS management that is sustainable, with a positive environmental profile, and long-term added values for a number of actors in the society.
- Multi-tree harvesting technique combined with the working method “Boom corridor Thinning”
- Combined harvesting and chipping technique
