- Red deer are increasing and spreading in Scandinavia. The species is capable of causing severe damage to Norway spruce through bark-stripping. We studied occurrence of bark-stripping on 18,000 trees in six study areas within two different regions in Sweden. The susceptibility for damage was related to morphological characters of the trees (bark thickness, branchiness, stem diameter) and whether the trees had old damage or not. In southernmost Sweden, 83, 89 and 92% of the stems were damaged in the three study areas, whereas 2, 8 and 46% was damaged in the three study areas in the region further north. Gnawing was the most common type of damage. Peeling was rare in the northern region but more frequent in the southern region. Bark-stripped trees had on average fewer branches, thinner bark and smaller diameter compared to undamaged trees. Furthermore, the risk of fresh damage was higher for already damaged trees in the northern region whereas the opposite pattern was evident in the southern region. Silvicultural measures may indirectly affect the risk of damage since it may affect branchiness, diameter and number of damaged trees left after thinning.
