Climatechange makes it hard to care for this trees here in germany. We used this spruce as a main tree for wood production for more than 200 years. Always harvesting and planting new spruces lead to the point that our Woods were made to over 50% from the norway spruce. Now we face summers with 2 months droughts and no rainfall at all. Thats when a 5mm long beetle lays his eggs in the cambrium of the spruce and kills the trees with its larvae by cutting of the watersupply from the Trunk to the top of the tree. In such summers the beetle kills the spruces in mass and acres of trees are even if still green on top dead from inside. It is mainly caused from the dry summers cause the tree cant defend itself from the beetle when it has no water to produce sap to drown the invading bettles in.
