During the winter storms, many trees have fallen or been damaged by heavy snow in G\u00f6taland and Svealand. This increases the risk of infestation by the spruce bark beetle, an insect that attacks weakened trees. The Swedish Forest Agency therefore urges forest owners to remove the damaged trees to reduce the risk of new infestations.<\/p>\n\n\n\n
The spruce bark beetle, which caused at least SEK 20 billion worth of damage after the hot summer of 2018, has decreased in number in recent years. To avoid a new wave of infestation, it is important to continue monitoring and removing damaged trees.<\/p>\n\n\n\n
Snowstorms have led to snowbursts, where branches and trunks have snapped, and to blown-down trees that now need to be dealt with. The damage is spread across G\u00f6taland and Svealand, with particularly serious problems in V\u00e4rmland, G\u00e4vleborg, Uppsala, Dalsland, V\u00e4stra G\u00f6taland, \u00d6sterg\u00f6tland, Kalmar and Sk\u00e5ne.<\/p>\n\n\n\n
In V\u00e4rmland, snow and wind caused snowfall and windfalls in the south-western part of the county, mainly in S\u00e4ffle and Grums municipalities. G\u00e4vleborg was affected by windfalls after Storm Hans and snowfall in the northern parts of the county. In Uppsala, snowfall occurred along the Uppland coast. Dalsland saw scattered fallen trees in the southern parts, while V\u00e4stra G\u00f6taland was affected by blown-down trees after Storm Louis. \u00d6sterg\u00f6tland saw both snowfall and whole trees falling, especially in the south-eastern part and north of the \u00d6stg\u00f6tasl\u00e4tten. In Kalmar, the northern parts were the worst affected, and in Sk\u00e5ne there was extensive snowfall in the south-eastern part.<\/p>\n\n\n\n
To reduce the risk of spruce bark beetle infestation, it is important to vary forest management and ensure that the forest is not too monotonous. A diverse forest, with trees of different ages and species, reduces vulnerability to insect pests.<\/p>\n\n\n\n
The Swedish Forest Agency emphasises the importance of forest owners being aware of damage in their forests and taking action to prevent the spread of the spruce bark beetle. Removing damaged trees quickly is crucial to minimise the risk of new infestations and to maintain forest health and productivity.<\/p>\n\n\n\n
In conclusion, this winter's storms have caused extensive tree damage, increasing the risk of spruce bark beetle infestation. Forest owners are encouraged to remove damaged trees and consider diversifying their forests to protect against future infestations. Coordinated efforts are necessary to protect forests and ensure sustainable forest management.<\/p>\n\n\n\n
