“…The most common tree species in Sweden, Norway spruce (Picea abies L. Karst) is one of the species that will have difficulty coping with higher temperatures and increased risk of wind damage (Spiecker et al 1996). Douglas fir is attractive, because its commercially valuable wood (Hermann and Lavender 1999) and potentially fast growth (Karlberg 1961;Nord-Larsen et al 2009). The species also has a wide site adaptability, and capacity to adapt to changing environmental conditions (Isaac-Renton et al 2014).…”

Key message The Douglas fir provenance Three Valley was found most suitable for planting in mid-Sweden. Greenhouse tests can most likely predict how different Douglas fir provenances will perform in the field. Abstract The need for species that will grow well through ongoing climate change has increased the interest in Douglas fir [Pseudotsuga menziesii (Mirb.) Franco] in Sweden. One of the most common problems seen in plantations of Douglas fir seedlings is damage caused by late spring frost, known to be highly correlated with the timing of bud burst. The objective of this study was to investigate spring-related bud development under Nordic conditions of seven Douglas fir provenances and to compare data with a local provenance of Norway spruce (Picea abies (L.) Karst). Results from a field trial and a greenhouse-based study were compared. The interior Douglas fir provenances exhibited an earlier bud burst than coastal provenances, both in the greenhouse and in the field trial. When comparing differences within the groups of interior and coastal Douglas fir provenances, no differences could be found. The local Norway spruce, only grown in the greenhouse, showed an intermediate bud development profile similar to the interior Douglas fir provenance Three Valley. We therefore suggest that Three Valley could be planted at the same locations as the investigated local provenance of Norway spruce in mid-Sweden. To avoid spring frost damage the Douglas fir seedlings need to be frozen stored and planted late in spring. Planting under shelterwood can also help protect the seedlings from spring frost damages. As similar results for bud development patterns of Douglas fir and Norway spruce provenances were obtained from the greenhouse and field trials, greenhouse tests could facilitate selection of provenances.

“…Considered species include lodgepole pine (Pinus contorta) and Sitka spruce (Picea sitchensis), which may grow more rapidly than their native relatives Norway spruce and Scots pine, respectively (Elfving et al 2001;Kristensen 2011;Gundale et al 2013). Douglas fir (Pseudotsuga menziesii) may also grow well and produces strong, wood with numerous applications (Hermann and Lavender 1999;Karlsson 2007). Two other introduced species that grow rapidly in appropriate conditions are hybrid larch (a cross between Larix decidua Mill.…”

There is increasing interest in using introduced species in Swedish forestry in response to climate change, but it is important to assess their resistance to native pests. Thus, we compared the extent of pine weevil feeding on two dominant native conifers, Scots pine ( L.) and Norway spruce ( (L.) Karst.), the non-host deciduous broadleaf hybrid aspen ( Ã HÃ¤met-Ahti) and four introduced conifers: Douglas fir ( (Mirb.) Franco), hybrid larch ( Ã Coaz), Sitka spruce ( (Bong.) CarriÃ©re) and lodgepole pine ( Douglas ex Loudon). The extent of feeding damage on seedlings and its effect on their vitality were examined in a field study in south-central Sweden and a laboratory experiment, which gave largely consistent results. Generally, the species most heavily attacked by the pine weevil, in both experiments, were Douglas fir and Sitka spruce. In the field experiment pine weevils killed or severely damaged significantly higher proportions of Douglas fir and Sitka spruce seedlings (60%) than any other species except Norway spruce (49%). Among conifer seedlings the proportions of killed or severely damaged seedlings were lowest for Scots pine and hybrid larch (27%) and Lodgepole pine (36%). The results indicate that most conifer species planted on young clear-cuttings in Sweden need some kind of pine weevil protection, and the possibility that introducing new tree species might increase damage caused by pests must be considered. For instance, widespread use of hybrid aspen could reduce damage by pine weevils, but increase damage by other, untested pests or pathogens.Pinus sylvestrisPicea abiesPopuluswettsteiniiPseudotsuga menziesiiLarixmarschlinsiiPicea sitchensisPinus contorta

“…Franco) has been cultivated as a valuable coniferous tree species in Europe since 1827. Th e ecological and economic relevance of the species has been long paid attention all over the world due to its rapid growth and high productivity (Göhre 1958;Fenton 1967;Aussenac 1980;Binkley 1983;Oswald 1984;Hermann, Lavender 1999;Dunbar et al 2002). In recent years the interest in Douglas-fi r has been related to the established theories of climate changes and the possibilities of the species to adapt itself to predicted changes (St. Clair, Howe 2007;Martin 2011;Eilmann, Rigling 2012;Leites et al 2012;Eilmann et al 2013;Bastien et al 2013).…”

Investigation of Douglas-fir provenance test in North-Western Bulgaria at the age of 24 years

2014

A comparative analysis of growth rate and health condition of 54 Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) provenances was conducted at the age of 24 years. The provenance test was established in 1990 with 3-year-old (3+0) seedlings planted in a 2 × 2 m plot design and two replications. The provenances which were studied originated from North America and were separated into coastal, continental and Western Cascade groups. In 2011 the growth rate was studied in terms of height, diameter at breast height and stem volume. The health condition was assessed by the evidence of symptoms and degree of defoliation caused by the fungi Phaeocryptopus gaeumannii (Rohde) Petrak and Rhabdocline pseudotsugae (Syd.). The provenances Newhalem, Darrington, Idanha and Bremerton were characterized by the most rapid growth, highest productivity and lower susceptibility to both fungal pathogens. These Douglas-fir provenances were recommended for future afforestation in Bulgaria. Ten continental provenances should be excluded from future afforestation because of their lowest growth rate and productivity and high susceptibility to P. gaeumannii and R. pseudotsugae.Keywords: adaptation; Phaeocryptopus gaeumannii; provenances; Pseudotsuga menziesii; Rhabdocline pseudotsugae; tree growth Douglas-fi r (Pseudotsuga menziesii [Mirb.] Franco) has been cultivated as a valuable coniferous tree species in Europe since 1827.
