Performance of Douglas-fir provenances on the crossroads of Central and Southeast Europe – growth, historical aspect, contemporary silviculture and adaptation possibilities

Douglas-fir is a species of increased importance in reforestation activities in Europe due to its higher potential for coping with predicting climate change in respect to declining Norway spruce. It has become important non native tree species in European forests. Provenance selection is essential for climate change adaptation of newly planted forests, both including afforestation and reforestation activities. In this respect, we stress the importance of long-term studies concerning introduced tree species since those are expensive and sensitive to ever changing managerial decisions. We discuss advantages and disadvantages of the use of 26 Douglas-fir provenances in continental and coastal area placed on the crossroads of Central and Southeast Europe (case studies from Croatia), both from historical aspect and contemporary silvicultural aspect. Study provides review on the research activities, which include 26 Douglas-fir provenances tested in the last 60 years. The intent of this review is to provide a synthesis of what is known about Douglas-fir provenances on the study area, to facilitate decision making on which provenance to use in afforestation and forest restoration programs. It tracks the performance of different provenances, providing insight into provenances with best and lowest survival and wood production. Review includes management and legislative legacy as well as state of the art of contemporary silvicuture. Since present legislative restrictions may omit the successful use of this tree species in Southeast Europe, special consideration is given to forest and nature conservation acts.
