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
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
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
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
- 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.
