Mixed forest areas
Locally adapted, mixed forests reduce the risk of deficiencies such as those resulting from storms or the proliferation of pests. In addition, they are helpful in adapting to climate change.
Under the Forest Policy 2020, the percentage of mixed forest areas should increase by 10% (NFI13 basis); however, this threshold value has not yet been achieved. Nevertheless, pure coniferous forests are not as heavily represented as they were in the 80s. The percentage of deciduous forests and mixed deciduous forests has risen, primarily at the lower altitudes, where deciduous forests are better adapted to the conditions.
The mixture of trees is sampled in forests, subsequently modelled and calculated for the entire forest area and producing regions.
