Moderate thinning increased hair lichens, while heavy cuts reduced them in Sweden‎

By using clearcutting, industrial forestry has caused a large-scale decline of hair lichens in Sweden's forests. In a large-scale field-experiment, researchers from Umeå University, University of Northern British Columbia, Canada, and Norwegian University of Life Sciences have shown that partial cutting can increase the abundance of hair lichens. The study is published in Forest Ecology and Management.
