The Canadian poplar in the secondary school car park on Palmenweg is more than 90 years old. His condition has been a cause of concern for a long time. An investigation by an independent tree expert revealed a definite rot in the stem and root body, which seriously affects the stability of the tree, especially when exposed to wind.

In addition, individual parts of the crown and branches are not supplied and are prone to breakage. The life of the tree cannot be extended by care measures, which are critically short and relatively costly.

Following an assessment and recommendation by the Nature Commission, which also had to determine the desolate status of the Canadian poplar, the city council decided to harvest in the winter months for safety reasons. There are no plans to plant a substitute in the same location, with views of neighboring cedar stock in front of the triple gym.
