But for forestry in general, it has little significance, says Ulrika Swärd, who is the function manager for nature conservation on the County Administrative Board and whose mission is to preserve the nature values ​​of the reserve.

- Only one percent of the spruce forest found in Östergötland is in a nature reserve, so it is a very small part of all spruce if you look at a landscape perspective.

Ulrika Swärd thinks that the County Administrative Board is doing enough to combat the spruce bark drill on the basis of the laws that exist, such as setting up traps and barking trees.

But the image of doing enough to combat the spruce bark's progress in the nature reserves does not fully share Patrik Oleinikoff. He works with forest management in Östergötland, Sörmland, Västmanland and Närke.

- In their places I have understood that enough has been done, but you see examples where it is completely dead since last year, and it just continues, says Patrik Oleinikoff.

- I do not see that it is the nature reserves that cause the damage but that it is more how you do forestry and that there are actually very many monocultures of spruce and that are sometimes planted in the wrong place too, says Ulrika Swärd.

Ulrika Swärd says that the Swedish Environmental Protection Agency and the Swedish Forest Agency are now investigating whether this is possible and whether it is appropriate that compensation should be given to those forest owners who have had their forest damaged next to a reserve.
