bark beetle infestation in the spruce forest
Forest dieback, amid hundrets of dead spruces after bark beetle infestation and long periods of drought, grows a small group of living green spruces in the Hevetal, Arnsberger Wald, Sauerland, NorthRhine Westphalia, Germany. How do they survive ? Is it another type of spruces, maybe resistant against the bark beetle ? A question for the experts. The spruces died because of the bark beetle infestation, the deciduous trees are alive and green. Forest dieback is a condition in trees or woody plants in which peripheral parts are killed, either by pathogens, parasites or due to conditions like acid rain and drought. Two of the nine tipping points for major climate changes, forecast for the next century, are directly related to forest diebacks.
