Direct seeding is used mainly for Scots pine and the regeneration results are mostly good; especially compared to natural regeneration. Looking at the results from the seed consumption point of view (seedlings per sown germinable seeds), the outcome in direct...
The posters are loaded with interesting and easily understood information about the use of trees and the importance of their genetic variation. The posters are made in cooperation with the Norwegian Centre for Science Education. They are in Norwegian, and...
In the Nordic region we are used to a simple and non-bureaucratic exchange of forest genetic resources between countries. This valuable exchange secures access to seeds and breeding material. The report ”Seeking appropriate legislation regulating access and exclusive rights to...

2006 was a good year for seed production, and the Swedish seed orchards for spruce produced almost twelve tons of seeds. This is enough for 1.2 billion plants that can regenerate 450 000 hectares. However, good years for seeding occur...
By Egbert Beuker, Finnish Forest Research Institute Evoltree includes 44 partners from 15 European countries, and it links four major disciplines (genomics, genetics, ecology and evolutionary studies). One of the sites chosen for intensive study is located in Punkaharju in...
By Mari Mette Tollefsrud, Norwegian Forest and Landscape Institute In Northern Europe only one main genetic main group is found, compatible with expansion out of one refugium which was in the southern part of Russia. In Central and Southern Europe,...
What can be done? Without knowing the basic biology of the fungus it is difficult to take appropriate actions against the disease, it is like fighting an invisible enemy. Some governments have decided to put restrictions on transfer of seeds...
