The climate change is becoming more and more noticeable in the forest: The increasing drought weakens the trees – which in turn are more susceptible to pests. According to the federal government, the amount of damaged wood in Germany has more than doubled in the past two years.
The amount of damaged wood decreases in SH
In the forests in Schleswig-Holstein, however, things look better. While more and more dry trees are attacked by the bark beetle and are dying in Hesse, North Rhine-Westphalia and Baden-Württemberg, the amount of damaged wood in Schleswig-Holstein is even decreasing. In the most densely forested district in Schleswig-Holstein – the Duchy of Lauenburg – there were 30,000 cubic meters of damaged wood two years ago, according to Kreisforsten – this year there are only 7,000.
Humidity compensates for a lack of rain
The main reason for the development was the cool and wet weather in spring, says Marcus Deinert from the district forests of the Duchy of Lauenburg. He explains: “ Up here in Schleswig-Holstein we always say: From a climatic point of view, we live on the island of the blissful. That has to do with our very strong ice-age structures in the soil. They are very well supplied with moisture and nutrients.” In addition, the location between the North Sea and the Baltic Sea leads to a relatively high level of humidity, which compensates for some of the lack of precipitation. However, there are also problems with dry soils in Schleswig-Holstein – especially in the sandy geest areas.
