For example, more cherries, maples and ash trees are being planted and care is being taken to promote existing trees. In principle, there has been no clear cutting in the forest for many years. Planting only takes place where larger open areas have been created by storms, snow breakage or bark beetles. Otherwise, we rely on natural regeneration, which means that the trees bear seeds and fruit from a certain age, which germinate in the ground and grow back into a stately trunk over the course of 100 to 200 years. This type of management, in which many tree species grow at different ages, not only offers ecological advantages in terms of biodiversity, but also positive economic effects in the long term.

The municipal forest has been managed naturally since 1988 and has been certified according to Naturland and FSC® (Forest Stewardship Council®, FSC® C007867) since 1999, thus combining careful management with a high standard of biotope and species protection. No pesticides are used and native tree species are planted or their regeneration promoted.
In addition, the naturally occurring tree species are already better adapted to the local conditions, so that the greatest possible diversity also supports the stability of the urban forest in the face of increasingly noticeable climate change and its consequences: The proportion of spruce is now only very low, as this tree species lacks precipitation; it no longer actually plays a role in the tree species composition.
