The natural world or The great outdoors or The environment - Adverse weather conditions could benefit forests by harming bark beetles.
Heavy rains over the past few weeks have pushed back the start of the beetle season for the pine processionary moth, providing some relief to forest owners. Friedrich Louen from Landesbetrieb Wald und Holz NRW explained, "Pine processionary moths thrive in stable, warm environments. The wetter it is, the more challenging it becomes for them." With the ground being so damp, spruces are now better equipped to fight off the pest compared to previous years.
Although optimistic, it's too soon to be carefree, as we must monitor the weather patterns to ensure there's no rain during summer, and no passing storms which could hinder our efforts in sorting out affected trees.
Since 2018, 143,000 hectares of forest have been affected by the interplay of pine processionary moths, storms, and drought - of which, around 40% of the spruces remain standing.

The heavy rains in Bonn, a city located in North Rhine-Westphalia (NRW), have positively impacted the forest ecosystem by delaying the bark beetle season. The wet conditions make it harder for pine processionary moths, which are known to thrive in stable and warm environments, to survive in the forest. As a result, the spruce trees in the forest, typically vulnerable to the pest, are now better prepared to ward off the attack. However, forest owners must remain vigilant, as unpredictable weather patterns such as summer rain or passing storms could still pose a threat.
