About Unit

IUFRO Working Party 1.01.08 Silviculture of Norway spruce deals with all aspects of silvicultural practices for forest types which include Norway spruce, ranging from pure, even-aged plantation forests to more diverse, natural or near-natural forests with Norway spruce as a more-or-less significant component.

WP 1.01.08 was founded during the IUFRO World Congress in Brisbane, Australia during 2005 as a continuation of a previous working party which focused on a European series of thinning experiments in Norway spruce. Future activities will include a large range of silvicultural issues as well as a broader geographical coverage.

At the IUFRO World Congress in 1961 in Vienna, G. Hellinga, Wageningen, addressed the silvicultural issues arising from increasing difficulties in marketing small-diameter trees. Subsequently, several IUFRO units focused their attention on this issue and numerous reports were presented in 1967 at the World Congress in Munich Following a proposal by J. Pardé, Nancy, Working Party 1.05.05 was established at this congress. P. Abetz, Freiburg im Br. was appointed the first leader of the working party.

The objective of the working party was to develop an experimental research program on thinning in even-aged Norway spruce stands and to establish and coordinate throughout Europe field experiments according to this program. The research program was well received by forest research institutions in those parts of Europe where Norway spruce is of major economic importance, and scientists were fascinated by the task of implementing the program.
