1. You shall every year inform in writing the municipalities affected about the field trial. A copy of the information shall be sent to the Board of Agriculture by 15 March every year,
2. You shall give the people who carry out the field trial careful written instructions on how the trial shall be carried out and cared for. A copy of the written instructions shall have come to the Board of Agriculture by 15 March 2018. You shall even send a copy if you make any changes in the instructions.
3. From the third week in February until two months after the leaves have opened, inspections are to be made every other week to discover if flower buds and disposition for forming flower buds has developed.
4. If you should find flower buds on the hybrid aspens during the field trial, you shall immediately report this to the Board of Agriculture, If trees are removed because it has been observed that flower buds are developing, the trees’ root systems should be removed or killed.
5. Within a 10 meter broad zone around the trial, vegetation should be held back by cutting at least once during the growing season. Within this zone, the presence of root shoots should be held back (not permitted).
6. Within a surrounding zone of 50 meter from the trial, wild growing aspens should be removed and controlled. The control should be chemically or mechanically at least once per year. Trees or shoots, where control measure have been started but where the plant is still alive, shall be marked so that is is clear that control measures are being taken.
7. The experimental plants in the trial shall be killed when the trial is ended.
8. If the Board of Agriculture requests it, you shall make maps or something similar available, that show where hybrid aspens and aspens with the different constructions are planted.
9. During the years that the pace is monitored for root shoots, cultivations that may take place on the field must be composed of plants that allow monitoring.
10. Test material from the trial and plants that is taken away shall be taken care of in a way that spread does not occur.
11. The place for the trial, including the protective zone of 50 meters around the trial, shall after clearing be monitored annually for the presence of root shoots, for a minimum of 3 years. Root shoots, if found, should be destroyed. For every year that you find root shoots, the monitoring will be extended for two years.
12. By 31 December every year that the trial is ongoing, you are to turn in a report. The report format that you are to use, is on the website of the Board of Agriculture. The report for the last year shall be a final report using the same format.
13. Reports of the results of the monitoring shall even be sent in the year following the area inspections for the presence of root shoots. Reposts on root shoot do not need to be given on any special form.
In addition: You have proposed a number of protective measures.
- The area is enclosed by a about 2 m high fence.
- The trees will not be allowed to flower. Control/inspection of the formation of flower buds will be made with inspections once a month from January until and including July. During the period from when the trees come into leaf and two months after, the inspections will be made every other week to discover if flowers could be formed in other places than normal. The Board of Agriculture has made this condition stricter so that the inspection should be made every other week from then middle of February. If a sign of swelling is noted on some plants the buds are to picked and opened to see if they are developing leaves or flowers. If it is development of flowers, all trees of that genotype are to be removed,
- The presence of root shoots is to be inspected during the vegetation period and held back. When the trial is ended, the hybrid aspens are to be cut down. The Board of Agriculture has defined this condition so that it is equivalent to the earlier approvals for permission.
