About 7% of forests are defined as natural or close to natural old-growth forests (Finnish Statistical Yearbook of Forestry 2014). Swedish forests are primarily boreal forests, although nemoral forests are found in South Sweden (Forests and Forestry in Sweden 2017). In general, the forest landscape in Sweden is dominated by commercially managed even aged forests, and old growth or untouched forests are rare (Forests and Forestry in Sweden 2017).
