Severe bark beetle attacks in Sweden

A comprehensive survey made by the Swedish Forest Agency indicates that spruce bark beetles have attacked and destroyed about 800,000 cubic metres of standing forest in Southern Sweden.

Not later than 15 August the storm felled timber should have been removed from roadsides in order to prevent it from becoming breeding ground for a new generation of spruce bark beetles. During August the Swedish Forest Agency has initiated investigations of storm felled timber that has not yet been taken care of.

In a press release Mr Lennart Svensson, manager of the Forest Agency's survey project, says that the situation is still serious. The cold and rainy weather this summer was favourable for the trees and unfavourable for the bark beetles, but nevertheless the beetle population is still considerable. The big amount of timber left in the forest and at roadsides after 1 July will probably constitute a risk of renewed attacks next year.

For the purpose of helping forest owners and forestry to find attacked trees the Forest Agency will conduct a helicopter inventory in August and September of certain regions in Southern Sweden. In areas where damaged forest is found forest — and landowners will be provided with maps indicating the location of the damage and written advice how to act. A follow-up of the extent of bark beetle damage will also be made in the course of the autumn.
