Douglas fir is a relevant timber species in European forestry. It grows well and produces valuable timber. The challenge for foresters is to choose those Douglas fir provenances for planting, which will perform well also in a changing climate with more drought events. In this study we take profit of large provenance trials with Douglas fir which have been established already in the 1960ies en 1970ies in the context of the IUFRO programs. Tree-ring analyses will be applied to assess the limiting effect of drought on long-term growth performance of different Douglas fir provenances to come up with concrete recommendations on suitable provenances for forest management.
The study involves fieldwork, labwork, tree-ring analyses. We seek for students who are interested in a subject on forestry with practical relevance. Co-supervision with Alterra will enable insights into collaboration between research and forestry practice. The subject is suitable to be executed in a team of 2 students!
