As a result of rapid climate change, forest ecosystems are transforming, leading to insect outbreaks, such as the large pine weevil (Hylobius abietis L.). In Europe, the pine weevil is considered one of the most significant pests of coniferous trees, causing substantial financial losses estimated at around € 120 million annually. To limit or reduce the impact of this pest, it is essential to take preventive measures; otherwise, in unprotected stands, the extent of damage can reach 60–80%. Damage caused by the weevil in forest stands leads to premature thinning of trees, which can significantly affect carbon accumulation in the forest stand, depending on the remaining stand density.
To determine how stand density affects the amount of accumulated carbon in Scots pine and Norway spruce stands, a mathematical model was developed. This model calculates carbon accumulation in the forest stand, taking into account both natural disturbances and forest management activities. In the model, stand density is gradually reduced by 5% increments up to a damage intensity of 60%, with the initial tree density being 2200 trees per hectare for pine and 1800 trees per hectare for spruce. The results show that the amount of accumulated carbon in the forest stand varies depending on the intensity of the damage. Therefore, it is essential in the future to also assess the economic benefits after final felling to determine whether significant financial losses are incurred, depending on stand density. The aim of this study is to determine how carbon accumulation in forest stands changes in response to varying damage intensities. |
