The two Norway maples were apparently knocked over by heavy equipment. Based on the tire tracks and the nature of the damage, it can be assumed that the trees were struck by a large vehicle or a piece of heavy machinery. The trunk circumferences of the two trees are approximately 50 and 65 centimeters, respectively, and they were planted about ten to twenty years ago.

In addition, the bark of an older, tall poplar was significantly damaged at a height of about two meters over an area with a diameter of approximately 50 centimeters. Given the height of the damaged area and the scrape marks present, it is also likely here that the damage was caused by a large vehicle or machine.

The damage to the two Norway maples was discovered on September 17 and 18, 2026. The second instance of damage was still fresh at the time of discovery and had therefore occurred within a period of less than 20 hours. The damage to the poplar was discovered on September 21, 2026, and is believed to have occurred between Friday and Monday morning.

“What shocks me most is that, based on current assessments, the damage patterns on all three trees indicate the deliberate—or at the very least, non-accidental—use of heavy equipment,” said Janina Steinkrüger, head of the environmental department. “The increasing periods of drought and heat are putting our trees under considerable stress. And then there are people who willfully damage trees for no apparent reason—that leaves me speechless.”

Not only is the ecological loss significant, but the preliminary estimate of financial damage to city property also amounts to approximately 6,000 euros. This is just one reason why the department head hopes that passersby can provide information about the perpetrators.
