計畫資料
Junkerdalsura nature reserve is known for its species rich pine and birch forests. Norway spruce was planted in parts of the reserve between the 1920s and 1960s. Restoration measures were therefore initiated to restore the native forest with its associated vegetation. Logging with timber extraction was carried out in two spruce plantations in 2018 and 2019, respectively, and a third spruce plantation was "veteranized" in 2021. The veteranisation aimed to damage the spruce trees so they would die gradually, providing dead wood to the area while at the same time allowing the native forest to regenerate. Vegetation analyses were conducted in these three former spruce plantations, as well as in adjacent control areas, in summer 2022.

取樣方法
Vegetation analyses were conducted in a total of 107 1x1 m plots placed randomly along 31 transects in both former spruce plantations and adjacent control areas. Each transect included 3-4 plots. The transects were placed approximately 20 m from other areas to avoid edge effects and, where possible, 10 m from other transects.
