Sažetak
Aim of the paper is to present stability of Douglas fir provenances in continental part of Croatia. Its durable, disease-resistant wood, rapid growth make it ideally suited for rapid reforestation and flexible forest management options. The aim of the research is to explore the success of different provenances in continental part of the country and to give the recommendations for forest establishment activities. Productivity of Douglas fir was evaluated on the basis of height and diameter growth. Volume production is analysed for 41st and 46th year after trial establishment. Research on basic structural parameters (DBH, total height, volume) was conducted on "Slatki Potok" locality. In each repetition, 25 seedlings (5x5) were planted, i.e. a total of 100 seedlings per provenance. Acquired data were statistically analysed with STATISTICA software. The most productive provenances originate from the lower altitudes of the Washington, Hvidilde (Denmark) and Shipka (Bulgaria). Provenance Castle Rock shows extremely low wood volume, which is result of its low survival, while the poorest wood volume shows provenance Shady Cove from Oregon. As results point to good success in comparison to forest cultures in the area of its natural distribution, there is a need of further research in Croatia.
