This paper builds on findings from the recently finalised work package 3.9 of the EU Indisputable Key project. Three institutes cooperated in developing intricate models spanning from the standing tree to the dispatch yard of a Swedish window manufacturer. Numerous timber properties were assigned to RFID tags, applied to the log at felling by a specially adapted harvester head. Logs were allocated to each of seven sawmills according to their timber properties using an LP based optimisation procedure. Simulation was then used to compare the fate of traced timber throughout the production lines of one of the sawmills and its downstream manufacturers.....

Cone and seed insects reduce seed production in seed orchards by feeding on cones and/or seeds and thus cause a lack of seedlings for reforestation. One of the most serious pest species in conifers is the spruce cone worm, Dioryctria abietella. Since 2007, we have used pheromone traps to monitor the flight of this species in Denmark, Finland, Norway and Sweden (and Estonia from 2009). In addition to monitoring, all countries have measured air temperatures in the vicinity of the traps. It is thus possible to correlate flight activity with temperature and temperature sums (accumulated day degrees >5°C). In Sweden cone development has also been registered throughout the monitoring period. Our results show that D. abietella has an extended flight period in Northern Europe, which lasts from late May to late September. Further research is needed to determine if late flying individuals oviposit on shoots or in cones. Increased knowledge about the flight period of D. abietella and how it coincides with temperature and cone development may help us develop better control measures against this important pest.
