Timber product oriented silvicultural strategies for mixed stands of beech (Fagus silvatica) and grand fir (Abies grandis).
A shortage of small dimensioned assortments of coniferous timber might hit the German timber market in near future. The fast growing grand fir, mixed with beech, could help to overcome this shortage. Product oriented silvicultural strategies for mixed stands of grand fir and beech, which were developed by the Northwest German Forest Research Station within the framework of the project "value-added chain forest-timber: beech/grand fir", are presented. The strategies are based on the results of the long-term observation of many cultivation, spacing and yield experimental plots which are scattered over a wide amplitude of forest sites. Additional data of single observations were used to complement the data set. The data were also used to extend the Northwest German version of the forest growth simulator BWINPro for grand fir in pure and mixed stands.
