The first joint Scandinavian variety testing for lawn (mowing height 25 mm), sport turf (mowing height 35, regular wear) and fairway (mowing height 15 mm) was carried out from 2005 to 2008 (http://www.scanturf.org/). The Nordic counties were divided into one northern (mostly continental, NZ) and one southern (mostly coastal, SZ) climatic zone with four and three test sites, respectively. Besides control varieties, 28 and 24 varieties were tested in NZ and SZ, respectively. Based on these trials the following varieties are candidates to be added to Nordic turfgrass cultivar guide for at least one climatic zone and at least one are of use (lawn, fairway and/or sport turf; control varieties are indicated in parantheses): Festuca rubra ssp. commutata: Bargreen, Greensleeves, Legende Margret, Rosetti 1 and Wagner 1 (Center) Festuca rubra ssp. trichophylla: Seabreeze (Barcrown) Festuca rubra: ssp. rubra, SZ: Celianna, Shadow II (Pernille, Frigg) Poa pratensis: Kaitos, Mozart 1 and Ravel 1 (Conni, Limousine) Lolium perenne: Vesuvius (Bargold) Agrostis capillaris: Leirin (Bardot, Nor)

In September 2009, a group of forest managers and researchers from Scotland, Sweden and Norway took part in a five day study tour in Norway. The tour focused on Scots pine forest management, timber processing and utilisation. It included visits to Scots pine forests, timber processing and manufacturing plants and the Norwegian Forest Extension Institute, which provides training to woodland owners and the wider forestry sector. The management and utilisation of Scots pine in the Northern Periphery area part of Norway was strongly influenced by a long tradition of family-owned farm forests (integrated with other land uses), local processing and widespread use of timber in construction. A key focus was the need to add value locally through secondary processing such as off-site construction methods for houses, preservative treatment of material for outdoor uses, and defect cutting and profiling for joinery.

The success of weed management aimed at depleting the regenerative structures of perennial weeds depends largely on the sprouting activity of rhizome and root buds. Seasonal variation in sprouting of these buds on Cirsium arvense, Sonchus arvensis and Elymus repens was studied for plants collected from Denmark, Finland, Norway and Sweden. At 2-week intervals from July to October, 5-cm fragments of roots or rhizomes were cut from plants grown in buckets and planted into soil in pots, half of which were placed immediately into growth chambers at 18 degrees C for 4 weeks. The other half of the pots were initially placed in a dark room at 2 degrees C for 4 weeks before being transferred to the same growth chamber, also for 4 weeks. During the growth chamber period, the numbers of emerged shoots in each pot were counted weekly. The sprouting activity of C. arvense and E. repens was relatively uniform during this period and bud dormancy was not apparent. In all ecotypes of S. arvensis, innate bud dormancy developed during the latter part of the growing season. For all three species, differences in sprouting readiness were found among ecotypes. The results imply that C. arvense and E. repens are more likely to be controlled by mechanical measures in autumn than S. arvensis.

In Norway, Nordmann fir (Abies nordmanniana) and subalpine fir (A. lasiocarpa) are the dominant Christmas tree species, and noble fir (A. procera) the dominant bough plant species. To determine if fungi found to cause diseases on fir in Norway might be seed borne, samples from twelve seed lots, including Nordmann fir from Austria, Georgia and Russia, subalpine fir from Canada and Norway and noble fir from Norway were tested using agar plate methods (PDA and WA). The most important finding was that Sydowia polyspora was present on seed from all firs from all countries (nine samples infected, 0.5 - 85 % infected seeds). Recently, it has been demonstrated in Norway that this fungus is the cause of current season needle necrosis (CSNN), which is considered a major disease in the Christmas tree and bough production both in Europe and USA. Sirococcus coniguenus was found in a Norwegian A. procera seed lot (31% infected seeds), which to our knowledge is the first report of this pathogen on fir seeds. Caloscypha fulgens was detected on subalpine fir seed from Canada. In addition the following fungal genera were detected: Acremoniella, Acremonium, Alternaria, Aspergillus, Botrytis, Chaetomium, Cladosporium, Diaphorte, Dictyopolyschema, Epicoccum, Fusarium, Genicularia, Mucor, Neonectria, Penicillium, Phoma, Rhizopus, Sordaria, Trichoderma, Trichothecium, and an unidentified fungus.

In Norway, Nordmann fir (Abies nordmanniana) and subalpine fir (A. lasiocarpa) are the dominant Christmas tree species, and noble fir (A. procera) the dominant bough plant species. Several fungal shoot and foliage diseases may reduce their marketability. To determine if fungi found to cause diseases on fir in Norway might be seed borne, samples from twelve seed lots, including five Nordmann fir (from Austria, Georgia and Russia), four subalpine fir (from Canada and Norway) and three noble fir seed lots (from Norway) have been tested using agar plate methods (PDA and WA). The most important finding was that Sydowia polyspora was present on seed from all firs from all countries. Recently, it has been demonstrated in Norway that this fungus is the biotic cause of cause current season needle necrosis (CSNN), which is considered a major disease in the Christmas tree and bough production both in Europe and USA. Sirococcus conigenus, causing shoot blight of several conifer species, was found in a Norwegian A. procera seed lot (31% infected seeds), which to our knowledge is the first report of this pathogen on noble fir seed. Caloscypha fulgens, the seed or cold fungus, was recorded at low levels on subalpine fir from Canada. In addition 20 fungal genera and an unidentified fungus were recorded. Species within some of these genera are known pathogens in nurseries and production fields.
