The storm, named “Hurricane Per”, comes two years after Hurricane Gudrun blew down about 75 million m3 of wood.

Forestry group Södra reported about 6 million m3 of wood blown down on its members’ lands – roughly the same as the volume of trees felled by Södra in six months.

But the group said lumber prices would remain unchanged, as would requirements for timber quality and freshness. It plans to remove windthrown trees from the forest by no later than June 1.

“The time is short, but taking out the windthrown trees any later than that is not an option, given the catastrophe that could result from the proliferation of the spruce bark beetle,” the group said.
