Trees have been felled at the entrance to the Forest Mullet trail in Tveta, Sweden. The trail is a walking trail where children can be challenged at different stations.
Parents have been worried that there is a risk of the damaged trees falling, says Henrik Skoglund, vice chairman of Södertälje-Nykvarn orienteering. Children learn about the spruce bark beetles in a preschool group at Grusåsen preschool, where the trees are part of the teaching.
